Answer:
50
Explanation:
Use the Pythagorean theorem to find the length of the diagonal, or the hypotenuse of an imaginary triangle. 30^2 + 40^2 = 2500, which is 50^2. So, the magnitude is 50.

To get the charge along the inner cylinder, we use Gauss Law
E = d R1/2εo
For the outer cylinder the charge can be calculated using
E = d R2^2/2εoR1
where d is the charge density
Use these two equations to get the charge in between the cylinders and the capacitance between them.
Answer:
Explanation:
It says “Momentum before the collision is equal to momentum after the collision.” Elastic Collision formula is applied to calculate the mass or velocity of the elastic bodies.
Answer:
(a)
(b)
Explanation:
<u>Given:</u>
- = The first temperature of air inside the tire =
- = The second temperature of air inside the tire =
- = The third temperature of air inside the tire =
- = The first volume of air inside the tire
- = The second volume of air inside the tire =
- = The third volume of air inside the tire =
- = The first pressure of air inside the tire =
<u>Assume:</u>
- = The second pressure of air inside the tire
- = The third pressure of air inside the tire
- n = number of moles of air
Since the amount pof air inside the tire remains the same, this means the number of moles of air in the tire will remain constant.
Using ideal gas equation, we have
Part (a):
Using the above equation for this part of compression in the air, we have
Hence, the pressure in the tire after the compression is .
Part (b):
Again using the equation for this part for the air, we have
Hence, the pressure in the tire after the car i driven at high speed is .
