Answer:

Force in the x component = 303.1[N]

Force in the y component = 175[N]

Explanation:

For the force of 350[N], we have the following components according to the angle.

[tex]F_{x}=350*cos(30) = 303.1[N]\\ F_{y}=350*sin(30) = 175[N]\\[/tex]

The components of the 350 N force acting on a box at a 30° angle are approximately 303 N horizontally and 175 N vertically, calculated using trigonometric functions.

To find the components of the force being applied to a 45 kg box that is pulled by a rope at an angle of 30 degrees, we can use trigonometric functions. Given a force of 350 N, we can break this force down into horizontal (x-component) and vertical (y-component) components. The horizontal component (Fx) is found using cosine function, and the vertical component (Fy) is found using sine function.

The horizontal component (Fx) is:
Fx = F × cos(θ) = 350 N × cos(30°)

The vertical component (Fy) is:
Fy = F × sin(θ) = 350 N × sin(30°)

Next, we calculate these values:

Therefore, the components of the force are:

As a truck rounds a curve, a box in the bed of the truck slides to the side farthest from the center of the curve. This movement of the box is a result of inertia.

Explanation:

We can answer this question by using Newton's first law of motion, also known as law of inertia, which says that:

"When an object is moving with constant velocity (or it is at rest), it will keep moving with same constant velocity (or it will remain at rest) unless acted upon an unbalanced force"

We can apply this law to the box in the bed of the truck. At first, the truck is moving in a straight line, with constant velocity: and so, the box is having the same motion.

However at some point, the truck begins the curve. If we neglect the friction between the box and the bed of the truck, then there is no other  force acting on the box in the horizontal direction: this means that the box will keep its horizontal motion, so it will continue moving forward with constant velocity, and therefore we will see the box sliding to the side farthest from the centre of the curve.

I got it right on the quiz! Good luck.

The second crewman should pull with an amount of force calculated through splitting the forces into components along and perpendicular to the direction of motion, and solving for the conditions that have to be met so that the net force is in the forward direction.

The subject at hand involves the calculation of forces in static equilibrium. A crucial concept used in this problem is the summation of forces both in the forward direction and perpendicular to it to ensure the net force is towards the forward direction. We add the forces like vectors, meaning we should take into account both their magnitudes and their directions.

Step 1: Calculate the y-component (perpendicular to forward direction) and x-component (forward direction) of the forces applied by the first crewman. The x-component equals force * cos(angle), and the y-component equals force * sin(angle). For the first crewman, x1= 130 cos(34) and y1 = 130 sin(34).

Step 2: The second crewman should pull such a way that his force's y-component neutralizes the first crewman's force's y-component and generates the same x-component to ensure the net force is in the forward direction. Hence, the forces for the second crewman should satisfy x1 = x2 and y1 = - y2. Therefore, for the second crewman, x2 = 130 cos(34) and y2= -130 sin(34).

Step 3: Use the Pythagorean theorem to calculate the force of the second crewman, which equals sqrt(x2^2 + y2^2). This will give you the magnitude of the force the second crewman should apply to ensure the net force is in the forward direction.

https://brainly.com/question/14215609

#SPJ3

The force exerted by the second crewman can be found by calculating the components of the forces involved, and requiring that they balance out to result in a net force in the forward direction only. This involves calculus and vector resolution in Physics.

The situation you're describing relates to vector resolution and addition in Physics. To find the force exerted by the second crewman, we'll need to use trigonometry. First, we can calculate the horizontal component of the force exerted by the first crewman, which is 130 N cos(34°), and the vertical component, which is 130 N sin(34°).

Since the net force should only be in the forward direction, the vertical component of the second crewman's force should exactly cancel out with the vertical component of the first crewman's force. Therefore, it should be equal to -130 N sin(34°). Given the angle of 45°, we can then express this force as F sin(45°) and solve for F.

So, if we set F sin(45°) = -130 N sin(34°), we can solve for F to find out the force that the second crewman should exert. This principle of resolving forces into components and adding them can be applied to a plethora of Physics problems, such as calculating the net force exerted on a barge by tugboats or the rate of acceleration of skiers towed by a boat.

Explanation:

The dependent variable is the thing that is measured when the independent variable is changed by us.

The independent variable would be the type of disinfectant so after you use the disinfectant you would measure the amount of bacteria meaning the answer would be D

The most logical dependent variable for Mario's experiment to determine the best disinfectant for killing kitchen bacteria is the number of bacteria that survived after disinfectant application.

In the experiment that Mario is planning, to determine which disinfectant is best for killing bacteria often found in kitchens, the most logical dependent variable would be option D, the number of bacteria that survived using the disinfectant. This is because the dependent variable is what the researcher measures to determine the effect of the independent variable, which in this case would be the type of disinfectant being tested. It's important to accurately measure the number of surviving bacteria to assess the effectiveness of each disinfectant.

Moreover, several factors can influence the effectiveness of a disinfectant, such as the concentration of the disinfectant, the temperature at which it is used, the types of microorganisms present, and the presence of organic material that can interfere with the disinfecting process. The goal is to choose conditions that optimize the contact between the disinfectant and the bacteria to achieve a satisfactory level of microbial control.

Volume = 20 x 10 x 5

Volume = 1000m³

Density = mass ➗ volume

Density = 150kg ➗ 1000m³

Density = 0.15kg/m³

I hope this was helpful, Please mark as brainliest  

Final answer:

The density of the substance is calculated by dividing its mass by its volume. With a mass of 150kg and volume of 1000m³, the density is 0.15 kg/m³.

Explanation:

To find the density of a substance, you need to divide its mass by its volume. The given mass of the substance is 150kg, and the dimensions provided are 20m by 10m by 5m. First, you have to calculate the volume by multiplying these dimensions together:

Volume = length × width × height = 20m × 10m × 5m = 1000m³.

Now, you can calculate the density using the formula:

Density = mass / volume = 150kg / 1000m³.

Therefore, the density of the substance is 0.15 kg/m³.

The acceleration is [tex]-3.1 m/s^2[/tex]

Explanation:

The acceleration of an object is the rate of change in velocity of the object.

Mathematically, it is given by

[tex]a=\frac{v-u}{t}[/tex]

where

u is the initial velocity

v is the final velocity

t is the time taken for the velocity to change from u to v

For the car in this problem, we have:

u = +20 m/s

v = 0 (because the car comes to a stop)

t = 6.5 s (time taken)

Therefore, the acceleration is

[tex]a=\frac{0-(+20)}{6.5}=-3.1 m/s^2[/tex]

Where the negative sign means that the direction of the acceleration is opposite to the direction of the initial velocity.

1.358 J is the kinetic energy of the car driven by Mrs. Waid.

Explanation:

Given data:

Velocity at which Mrs. Waid drives her car = 80 mph

In order to convert mph (meter per hour) into mps (meter per second),

         [tex]\frac{80}{3600}=0.0222 \mathrm{m} / \mathrm{s}[/tex]

Car weighs 2500 lbs, means mass of the car, m = 2500 lbs

I kilo gram = 2.20462 pound

Therefore, 1 pound (lb)=  0.45359237 kilograms (kg).

To converting pounds into kilogram,

               [tex]\frac{2500}{0.45359237}=5511.55 \mathrm{kg}[/tex]

As we know, the kinetic energy can be defined as directly proportionate to the object’s mass (m) and square of its velocity (v). The expression can be given as below,

               [tex]\text { kinetic energy }(K . E)=\frac{1}{2} \times m \times v^{2}[/tex]

By substituting the given values, we get

Answer:

13 m/s

Explanation:

Momentum is conserved, so initial total momentum = final total momentum.

m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂

Since Car B is originally not moving, u₂ = 0.

m₁ u₁ = m₁ v₁ + m₂ v₂

Since the cars stick together, they have the same final velocity, so v₁ = v₂ = v.

m₁ u₁ = m₁ v + m₂ v

m₁ u₁ = (m₁ + m₂) v

Given that m₁ = 1800, m₂ = 1500, and v = 7.1:

1800 u₁ = (1800 + 1500) 7.1

u₁ = 13

Car A was travelling at 13 m/s.

Using the heat conduction formula, we determined that 432000 joules of heat flows through the slab in one day, given the thermal conductivity, area, temperature difference, time, and thickness of the material.

Explanation:

To calculate the amount of heat flow through the slab, we use the heat conduction formula: Q = (k*A*ΔT*t)/d, where:

k is the thermal conductivity,

A is the cross-sectional area,

ΔT is the temperature difference,

t is the time, and

d is the thickness of the material.

Giving us the following values to use in the formula: k = 0.1 J/s.m.ºC, A = 100 cm2 (or 0.01 m2 when converted to square meters), ΔT = 100 ºC, t = 1 day (or 86400 seconds), and d = 2 cm (or 0.02 m).

Q = (0.1 J/s.m.ºC * 0.01 m2 * 100 ºC * 86400 s)/0.02 m,
Q = (0.1 * 0.01 * 100 * 86400)/0.02,
Q = 432000 J.

Therefore, 432000 joules of heat flows through the slab in one day.

The amplitude of oscillation is 0.33 m

Explanation:

Amplitude is the measure of change in distance occurred during oscillation. As oscillation is a to and fro motion, so amplitude consists of influence of angular frequency and maximum velocity.

It is known that velocity is maximum when the spring is in equilibrium. And angular frequency of spring is determined as the square root of spring constant divided by mass.

[tex]angular frequency=\sqrt{\frac{spring constant}{Mass} }[/tex]

Angular frequency =[tex]\sqrt{\frac{18.9}{0.250} }=8.69[/tex]

And amplitude is

Answer:

A low frequency sound (say, 50 hz) might sound like a low rumble, while a high frequency sound (say 12,000 hz), might sound more like a "sizzle". ... The higher the frequency, the shorter the distance between each successive compression (or rarification) in the incoming sound wave. This distance is called the "wavelength".

Explanation:

The number of cycles per second (Hertz) (abbreviated as, hz) of anything that oscillates is called the "frequency". The electricity of an AC wall outlet is said to have a frequency of 60 Hertz as it cycles negative then positive 60 times each second.

Sound is an oscillating wave, but it has a broad range of frequencies. A low frequency sound (say, 50 hz) might sound like a low rumble, while a high frequency sound (say 12,000 hz), might sound more like a "sizzle". A person with normal hearing can hear all the way up to about 20,000 hz.

Sound is actually more like "compression" waves, rather than waves on the ocean. When something makes a sound, the air is compressed or rarified in waves that travel out from that source in all directions. When those compressed or rarified areas of air hit your eardrum, it vibrates in sympathy with those compression waves in the air and allows you to hear.

The higher the frequency, the shorter the distance between each successive compression (or rarification) in the incoming sound wave. This distance is called the "wavelength". Sound travels at about 750 miles/hour, so the compression waves between 100 hz and 20,000 hz have wavelengths that range between several feet (for the 100 hz sound) to a fraction of an inch (for the 20,000 hz sound).

Speech also has a range of frequencies, but it mostly limited to the range between a hundred (or so) hz and 8,000 (or so) hz. The frequencies that make up vowel sounds are typically lower frequencies, while the consonant sounds (at least the parts that help us hear which consonant sound was spoken) tend to be higher frequency sounds.

People with even moderately good hearing up to about 3,000 hz can understand speech fairly well. Wired telephones typically do not transmit sound above 3,500 hz.

When people have a hearing loss, they usually have less ability to hear some frequencies than to hear other frequencies. This creates a distortion that can make it difficult to understand speech. Usually, people with hearing loss have poorer hearing in high frequencies than in low frequencies, but some people may lose lower frequencies, or even middle frequencies, while having less loss in other frequencies.

Hearing aids now have the ability to be tuned to amplify different frequencies by differing amounts, so that it fills in where you need the amplification without giving you too much sound in frequencies where you hear better.

The low frequency wave has longer wavelength and less energy compare to high frequency waves.

The frequency of a repeated event is its number of instances per unit of time. It differs from angular frequency and is sometimes referred to as temporal frequency for clarification. The unit of frequency is hertz (Hz).

A wave's wavelength and frequency are inversely proportional. Accordingly, waves with high frequencies have a short wavelength, whereas waves with low frequencies have a longer wavelength.

Very, very short wavelengths characterize light waves. While blue and purple light have even shorter waves with wavelengths around 400 or 500 nanometers (nm), red light waves have wavelengths about 700 nm. With wavelengths ranging from millimeters to kilometers, radio waves, another kind of electromagnetic radiation, have far longer waves than light.

Answer:

The frequency would double.

Explanation:

Given:

Speed of wave (v) = constant.

Frequency of wave initially (f₁) = 2 Hz

Initial wavelength of the wave (λ₁) = 1 m

Final wavelength of the wave (λ₂) = 0.5 m

Final frequency of the wave (f₂) = ?

We know that the product of wavelength and frequency of the wave is equal to the speed of the wave.

Therefore, framing in equation form, we have:

Wavelength × Frequency = Speed

[tex]\lambda\times f=v[/tex]

It is given that speed of the wave remains the same. So, the product must always be a constant.

Therefore,

[tex]\lambda\times f=constant\ or\ \\\lambda_1\times f_1=\lambda_2\times f_2[/tex]

Now, plug in the given values and solve for 'f₂'. This gives,

[tex]1\times 2=0.5\times f_2\\\\f_2=\frac{2}{0.5}=4\ Hz[/tex]

Therefore, the final frequency is 4 Hz which is double of the initial frequency.

f₂ = 2f₁ = 2 × 2 = 4 Hz

So, the second option is correct.

Answer:

The answer is C The frequency would double.
