Answer:
PnP transistor is a current controlled device. It has two crystal diodes connected back to back. The left side of the diode is known as the emitter-base diode and the other side which is the right side of the diode is known as the collector-base diode.
Answer:
A transistor is of two types: PNP and NPN
Explanation:
A transistor is current controlled device in which the current flow by the movement of the electrons and wholes.
The NPN and PNP transistor are the types of the BJT (Bipolar junction transistor) that have two uses i.e switching and amplification.
A PNP transistor have three junction i.e P, N and P where the base is connected to the N - junction. The P junction is high in number of wholes and N- junction have high numbers of electrons.
In the PNP transistor the voltage is provided to the emitter and base terminal with base connected to the negative terminal of the voltage source and emitter connected to its positive terminal. The direction of the flow of the current is from emitter to collector whenever a significant voltage is provided to the emitter base junction.

The resultant of two forces p and q is 260N .if q is 80N and the angle between p and q is 30° find q
Answer:
256.9N
Explanation:
q is the other component of the forces when resolved using 260sin30=0
Answer:
q is already given so i assume you question is find P
p = 187.6N
Explanation:
\widehat{p\ }+ \hat{q} = \hat{R}
R = 260N
q = 80N
angle between p and q is 30°
Therefore, the angle the two vectors make to produce R is (180° – 30° = 150°) = 150°
Resolving q in x and y components = (80 cos 30)i + (80 sin 30)j
q = 69.3i + 40j
R = p + q
Let p = xi + yj
R = (xi + yj) + (69.3i + 40j)
R = 260N
Resolving R in x and y components
R = (260 cos \theta)i + (260 sin \theta)j
(260 cos \theta)i + (260 sin \theta)j = (xi + yj) + (69.3i + 40j)
(260 cos \theta)i + (260 sin \theta)j = (x + 69.3)i + (y + 40)j
Equating each component to the corresponding component
x + 69.3 = (260 cos \theta)……(i)
y + 40 = (260 sin \theta)……….(ii)
y = 0
0+ 40 = (260 sin \theta)
\theta = sin-1 (\frac{40}{260})
\theta = 8.8°
x + 69.3 = 260 cos 8.8°
x = 260 cos 8.8° - 69.3
x = 187.6i
p = 187.6N

Explanation:
A vacuum gauge indicates that the pressure of air in a closed chamber is 02 bar ( vacuum) The pressure of the surrounding atmosphere is equivalent to 750 in of mercury The density of mercury is 13.95 g/ cn and the acceleration of gravity is 9.8. / Determine the absolute pressure within the chamber in bar.
Answer:
Pvac = 0.2 bar
Patm = 750 mm Hg
P Hg = 13.59 g/cm^3 * (1kg/10^3g) (10^2cm/1m)^3 = 13590 kg/m^3
g = 9.81 m/s^2
Patm = P Hg*g*L Hg
= 13590 kg/m^3 * (9.81 m/s^2) * (0.75 m)
= 100 * 10^3 * 1N/1kgms^-2 * 1 bar / 10^5 Nm^-2
= 1 bar
Pabs = Patm - Pvac = 1-0.2
= 0.8 bar
The absolute pressure within the chamber is 1.187 bar, calculated by adding the vacuum gauge reading (0.2 bar) to the atmospheric pressure (0.987 bar).
To determine the absolute pressure within the chamber, we need to consider the difference in pressure between the chamber and the surrounding atmosphere.
Given:
- Vacuum gauge reading: [tex]\(0.2 \, \text{bar}\)[/tex] (vacuum)
- Atmospheric pressure: [tex]\(750 \, \text{mmHg}\)[/tex]
- Density of mercury: [tex]\(13.95 \, \text{g/cm}^3\)[/tex]
- Acceleration due to gravity: [tex]\(9.8 \, \text{m/s}^2\)[/tex]
We'll first convert the atmospheric pressure from mmHg to bar:
[tex]\[ P_{\text{atm}} = \frac{750 \, \text{mmHg}}{760 \, \text{mmHg/bar}} = 0.987 \, \text{bar} \][/tex]
Now, we'll find the absolute pressure within the chamber by adding the vacuum gauge reading to the atmospheric pressure:
[tex]\[ P_{\text{absolute}} = P_{\text{vacuum}} + P_{\text{atm}} = 0.2 \, \text{bar} + 0.987 \, \text{bar} = 1.187 \, \text{bar} \][/tex]
So, the absolute pressure within the chamber is [tex]\(1.187 \, \text{bar}\)[/tex].

A rectangular conductor with a cross sectional area of 1.04 square millimeters (mm) ^2 has a resistance of 0.075 ohms. What would be its resistance, if it's cross sectional area were 2.08mm^2
Answer:
0.0375 ohms
Explanation:
The resistance of a material is the product of the resistivity of the material by the length of the material divided by its cross-section area.
Mathematically,
resistance= resistivity × length/area
In this case the resistivity of the material is the same, and the length is the same thus, assume a length of 1 unit, the cross-section area is the one changing
In applying the formula,
resistivity is r and length is l=1 unit, find the resistivity the material as;
resistance= resistivity * length /area
0.075=r*1/1.04
0.075=r*0.9615
0.075/0.9615 =r
r=0.078
use the r=0.078 , a length of 1 unit (assumed), and area of 2.08 mm² to find the new resistance
Resistance= resistivity * length /area
Resistance = 0.078*1/2.08
Resistance= 0.078 * 0.4807 = 0.0375 ohms
Point to note here is that the greater the cross-section area, the less the resistance.

Multi lane roads use __ to divide lanes of traffic moving in the same direction.
A. White lines
B. Yellow lines
C. Diagonal stripes
D. Orange stripes
Answer:
A. White lines
Explanation:
Multi lane roads use White lines to divide lanes of traffic moving in the same direction.
While driving, we occasionally see certain types of lines on the road.
There are various sorts of roads. There might be single lanes, double lanes, multilane lanes, etc. Similar to how the lines that we see on these lanes are different.
White broken lines are used to divide the lanes when there are several lanes travelling in the same direction, typically three or four lanes. Depending on the speed and traffic in the lanes, people can change from one lane to another.
However, there are also some locations on the highways where these crooked lines solidify, at which point it is illegal to change lanes until the crooked white lines are once again visible.

Why is it challenging to develop a problem statement for a project? What action can you take to work around this challenge to identify the problem?
A Problem Statement:
A problem statement is away from the depiction of the issue(s) that need(s) to be tended to by a critical thinking group. It plainly states what circumstance you're managing, why it's an issue, and what your optimal state would be. A straightforward and very much characterized issue proclamation will be utilized by the task group to comprehend the issue and work toward building up an answer.
An issue articulation is typically a couple of sentences to clarify the issue your procedure improvement task will address. When all is said in done, an issue explanation will plot the negative purposes of the present circumstance and clarify why these issues. Issue articulations frequently have three components: the issue itself, expressed obviously and with enough logical detail to set up why it is significant; the technique for taking care of the issue, regularly expressed as a case or a working proposal; the reason, explanation of goal and extent of the report the author is getting ready.

Which description defines the mechanical advantage of a simple lever?
A.
the ratio of the total lever length to the length of the effort arm
B.
the ratio of the length of the load arm to the length of the effort arm
C.
the ratio of the length of the effort arm to the length of the load arm
D.
the ratio of the length of the load arm to the total lever length
E.
the ratio of the length of the effort arm to the total lever length
The mechanical advantage of a simple lever is C. the ratio of the length of the effort arm to the length of the load arm
Explanation:
There are two types of mechanical advantage for a machine:
The Ideal Mechanical Advantage (IMA) is the mechanical advantage of the machine if there are no loss of energy due to internal frictions, i.e. if the output work is equal to the input workThe Actual Mechanical Advantage (AMA) is the real mechanical advantage of the machine, taking into account the energy lost due to internal frictional forcesThe IMA of a lever can be calculated starting from the assumption that all the input work is transformed into output work with no loss of energy, therefore:
[tex]W_{in}=W_{out}\\F_{in} d_{in} = F_{out} d_{out}[/tex]
where
[tex]F_{in},F_{out}[/tex] are the effort and load forces, respectively
[tex]d_{in}, d_{out}[/tex] are the effort and load arm, respectively
The mechanical advantage is a measure of the multiplication factor of the force, so we can write:
[tex]IMA=\frac{F_{out}}{F_{in}}=\frac{d_{in}}{d_{out}}[/tex]
Therefore, the correct answer is
C. the ratio of the length of the effort arm to the length of the load arm

Answer:
who's value.
Explanation:
Answer: I believe the word you are looking for is tolerance.
Explanation:
Some resistors have only three bands on their outer casing, which means that the tolerance band is blank. This means the tolerance has a default value of plus or minus 20 percent. For example, a 1k-ohm resistor would have an actual value that measures from 800 to 1200 ohms, since the tolerance would be 200 ohms.
