Nitrogen -13 has a half life of 10 minutes how long will it take for a sample of 500 g to be reduced to 62.5 g?
Answers
Answer:
30 minutes
Explanation:
Use half life equation:
A = A₀ (½)^(t / T)
where A is the final amount, A₀ is the initial amount, t is time, and T is the half life.
A = A₀ (½)^(t / T)
62.5 = 500 (½)^(t / 10)
0.125 = ½^(t / 10)
t / 10 = 3
t = 30
It will take 30 minutes.
Final answer:
To find the time it takes for a 500 g sample of Nitrogen-13 to be reduced to 62.5 g, we can use the equation for radioactive decay. The time is approximately 40 minutes.
Explanation:
To solve this problem, we can use the equation for radioactive decay: N = N0 * (1/2)(t/t1/2), where N is the final amount, N0 is the initial amount, t is the time passed, and t1/2 is the half-life. In this case, we have N = 62.5 g, N0 = 500 g, and t1/2 = 10 minutes. Substituting these values into the equation:
62.5 g = 500 g * (1/2)(t/10)
Now, we can solve for t by taking the logarithm of both sides and rearranging the equation:
t = 10 * log2(62.5/500)
Using a calculator, the value of t is approximately 40 minutes.
How Far East have you traveled if you ran 80 meters northeast
Answers
The student has traveled approximately 56.57 meters east.
In this case, the student has traveled 80 meters in a northeast direction. To determine how far east the student has traveled, we need to find the eastward component of their displacement.
Since the northeast direction can be broken down into equal north and east components, we can use trigonometry to determine the eastward displacement.
By using the sine function, we can find that the eastward displacement is approximately 56.57 meters.
A body that goes a distance and then returns to its starting point has the same beginning and ending points. In this case, the displacement is zero, but the distance travelled is not. It is possible to have zero, negative, or even positive displacements.
Therefore, the average velocity is usually 0 when the overall displacement is zero. To gain a better understanding, keep in mind that a body's displacement is a vector, meaning it depends on its direction. Its precise definition is the object's position change rate in a given direction.

B.
Stars in the sky appear to move slowly from north to south.
C.

D.

Answers
"Stars in the sky appear to move slowly from east to west" is true about the movement of stars in the night sky.
Answer: Option D
Explanation:
The Sun, Moon and stars all are understood to wake up in the East and set in the West direction, as every 24 hours the Earth rotates on its axis in the reverse direction from West to East. Consequently, the acceleration we witness is not their action, but ourselves as we go zipping onto the Earth's surface to the North, and these gravitational anomalies fly over us. For illustrating this point, the North Star named as Polaris in Ursa Minor is useful.
Stars in the night sky seem to move slowly from east to west due to the Earth's rotation.
Stars in the sky appear to move slowly from east to west. This apparent motion is due to the rotation of the Earth. As the Earth rotates from west to east, the stars appear to move in the opposite direction.

A bowling ball rolling at a certain speed has a kinetic energy of 12 J. What will be its new kinetic energy if it now rolls at 3 times the old speed?
Answers
The new kinetic energy of the bowling ball is 108 J,
Answer:
Explanation:
Any object in motion will experience an amount of kinetic energy. So the kinetic energy is directly proportional to the product of mass and square of velocity of the object. In the present case, the bowling ball is experiencing a kinetic energy of 12 J.
So, K.E. = 12 J = [tex]\frac{1}{2}mv^{2}[/tex]
As the ball will be having same mass, so when the velocity is increased three times of old velocity, so new speed will be 3v, where v is the old speed. Then the new kinetic energy will be as below:
New kinetic energy = [tex]\frac{1}{2}m(3v)^{2} = \frac{9}{2}mv^{2}[/tex]
Since we know that [tex]\frac{1}{2}mv^{2}[/tex] = 12 J, substitute this in new kinetic energy equation and we get
New kinetic energy = 9 × 12 J = 108 J.
Hence the new kinetic energy of the bowling ball is 108 J, when the new speed is three times the old speed,
The deepest mine ever drilled has a depth of 12300 meters. suppose you drop a rock with a mass of .12 kilograms down the shaft of this mine. What would the rock's kinetic energy be after falling 3200 meters? What would the potential energy associated with the rock be at that same moment? Assume no air resistance and a constant free-fall acceleration. (please show the equations used and why you used these equations.) Thank you.
Answers
Answer:
Correct answer: Ek = 384,000 J = 0.384 · 10⁶ J = 0.384 MJ
Ep = 1,092,000 J = 1.092 · 10⁶ J = 1.092 MJ
Et = 1,476,000 J = 1.476 · 10⁶ J = 1.476 MJ
Explanation:
The total energy at all times is equal to the sum of kinetic and potential energy.
Et = Ep + Ek
We will take the bottom of the mine as a reference point
We can solve this problem combined with the help of kinetics and energy conservation laws, or just with energy conservation laws, which I will do.
Before we drop a rock the potential energy is maximum and the kinetic energy is equals to zero.
The formula for calculating potential energy is:
Ep = m g h , we will take that g = 10 m/s²
This is the maximum potential energy (or total energy)
Epmax = Et = 12 · 10 · 12,300 = 1,476,000 J = 1.476 · 10⁶ J = 1.476 MJ
After a fall of 3,200 m the rock will be on height of 9,100 m and its potential energy will be:
Ep = m g h₁ = 12 · 10 · 9,100 = 1,092,000 J = 1.092 · 10⁶ J = 1.092 MJ
The difference between the maximum potential energy (or total energy) and the potential energy at height h₁ is actually kinetic energy.
Ek = ΔEp = Et - Ep = 1,476,000 J - 1,092,000 J
Ek = 384,000 J = 0.384 · 10⁶ J = 0.384 MJ

if a star 100 light years from earth is beginning to expand into a giant star how long will it take for astronomers to observe this development explain
Answers
Final answer:
If a star 100 light-years away begins to expand, it will take 100 years for astronomers on Earth to observe the event, as light from the expansion will take that long to travel the distance to our planet.
Explanation:
If a star 100 light-years away from Earth is beginning to expand into a giant star, astronomers will observe this development after 100 years. This delay is because the light from that event will take 100 years to travel the distance from the star to Earth. As light is the fastest thing in the universe, moving at over 186,000 miles per second, it is the speed at which we receive information from the cosmos. So, even if the star began to expand today, we would not be aware of it until 100 years later - when the light showing the star's expansion arrives here. This concept is similar to observing galaxies through the universe, which allows us to see them as they were when the light left them, essentially looking back in time.

which formula is used to calculate the change in an object's momentum
Answers
Answer:
The change in momentum of an object is its mass times the change in its velocity.
The formula to calculate the change in momentum of the object is ΔP= m( Vf - Vi).
What is a change in momentum?The change in momentum is equal to the product of the mass and the velocity change. Because mass is a constant value, it remains constant. The change in velocity causes a change in momentum.
The change in momentum is calculated as the difference in the velocities of the object.
Momentum is the product of an object's mass and velocity and describes mass in motion. Impulse: An impulse is a force that causes a change in motion. The change in momentum of an object, p=m(vf-vi) p = m (vf- vI p = m (vf - vI is equivalent to the impulse, J.

Explanation:
Description 1 matches C. From graph C, we can see that the distance remains constant at a particular value. Hence, the car is not traveling and hence it is stopped.
Description 2 matches A. Speed is determined by the gradient of a distance-time graph. A depicts a linear graph which tells us that the gradient is constant and hence the car is at constant speed. The fact that the distance is increasing shows that the car is moving forward.
Description 3 matches D. Graph of D becomes less steeper as time progresses. This tells us that the gradient of the graph is decreasing and hence the speed of the car is decreasing.
Description 4 matches B. Graph B shows distance being decreased. This tells us that the car is coming back.

D. Acceleration is positive and velocity is negative.
Answers
Answer:
(C) acceleration is a change in velocity.
Explanation :
Acceleration is the rate of change of velocity with time.
Acceleration is the rate at which velocity changes, making option C ('Acceleration is a change in velocity.') the most accurate description of the relationship between velocity and acceleration.
Explanation:The most accurate description of the relationship between velocity and acceleration is that acceleration is the rate at which velocity changes. Therefore, the correct answer to the question is 'C. Acceleration is a change in velocity.'
Acceleration is a vector quantity, which means it has both magnitude and direction. It can result from a change in speed, a change in direction, or both. Velocity is also a vector that describes the speed of an object in a given direction. When an object's velocity changes, it is accelerating, which can be a result of increasing speed, decreasing speed, or changing direction.
In summary, while velocity is the rate of change of position with time, acceleration is the rate of change of velocity with time.

These could be changes in its eccentricity or even tilt in the axis.These cycles caused due to small changes have different effects on how much solar energy reaches the Earth and the time at which maximum sunlight is received.These cycles are very important as the amount of solar energy or sunlight reaching the Earth also affects the climate on the Earth. The ice ages are examples of such changes in the climate. They are strongly connected to the changes in the orbit of the Earth.The Milankovitch cycles affect the amount of solar energy reaching Earth through changes in Earth's orbital shape and axial tilt over thousands of years. The correct option is B) the amount of solar energy that reaches Earth.
Explanation:The Milankovitch cycles affect the amount of solar energy that reaches Earth. These cycles consist of changes in Earth's orbit and axial tilt over thousands of years. Of the options provided, B) the amount of solar energy that reaches Earth is the aspect that is changed by the Milankovitch cycles. Specifically, eccentricity, which is one of these cycles, alters the shape of Earth's orbital path from more circular to more elliptical over approximately 100,000 years. This affects the proximity of Earth to the sun during various parts of the orbit, thereby influencing the solar radiation the planet receives.

The Concept of attraction & Repulsion
The basic concept of attraction and repulsion between two similar and opposite poles of a bar magnet is that the ends of two bar magnets with similar strongly repel each other whereas poles of opposite polarity attract each other.
Since B and C are of opposite polarity, they will repel each other with minimum forces whereas A and D are of opposite polarity as well, hence they will attract each other with maximum forces when placed together.
We can flip the options accordingly saying, B and C will have the maximum attraction while A and D will have the minimum repulsion when placed together.

Answers
Friction decreases the kinetic energy which decreases the mechanical energy.
Explanation:When two object moves one over the other, the resistance that is faced by the object is called as the friction. Any force that restricts the motion of any moving or any object that is sliding is called as friction. A kinetic energy can be considered as a non conservative energy that reduced the mechanical energy of any moving objects.
A friction can be considered as a force that resits motion of an object. When there a movement of two objects one against the other, there will be a conversion of kinetic energy into heat energy. This conversion is caused by the friction. Thus, the kinetic energy reduces the mechanical energy and they will be converted into heat energy.
Friction is a force that opposes motion, transforming mechanical energy into other forms like heat, effectively reducing the system's mechanical energy.
Explanation:Friction is a force that opposes the movement or motion of an object. In a system, when there is movement, friction comes into play. Mechanical energy is the sum of kinetic and potential energy in a system. As friction acts against movement, it transforms the mechanical energy within the system into other forms of energy, such as heat energy, which reduces the system's mechanical energy. Let's consider a sliding block for example. As the block slides, the friction between the block and the surface generates heat, thus reducing the mechanical energy (kinetic energy) of the block.
