What is capacitance?

Physics
1 answer:
WARRIOR [948]3 years ago
4 0

capacitance of any given capacitor is given by the formula,

C=Q/V

where C=capacitance,Q= charge and V=voltage

therefore from the formula capacitance is charge per unit voltage.

Sam's bike tire contains 15 units of air particles and has a volume of 160mL. Under these conditions the pressure reads 13 psi.
vichka [17]
Use ideal gas equation, with T constant.

pV =nRT => pV / n = RT = constant

n = K* [units of particles]

pV / [units of particles] = constant

13 psi * 160 mL / 15 units = p * 150 mL / 10 units =>

=> p = [13psi*160mL/15units]*[10units/150mL] = 9.2 psi

A 0.70-kg basketball dropped on a hardwood floor rises back up to 65% of its original height. (a) If the basketball is dropped f
dem82 [27]

Answer:

Part a)

Loss = 3.6 J

Part b)

Loss = 0.99 J

Part C)

This is loss in terms of thermal energy due to collision with the floor

Explanation:

Part a)

Since we know that the ball rises up by 65% of initial height

so after first bounce it will lose 35% of its initial energy

so we will have

U = mgH

Energy Loss = 0.35 mgH[/tex]

Loss = 0.35(0.70)(9.81)(1.5)

Loss = 3.6 J

Part b)

Energy of the ball after first bounce

U_1 = 0.65 mgH

energy of ball after 2nd Bounce

U_2 = 0.65(0.65 mgH)

energy of the ball after 3rd bounce

U_3 = (0.65)(0.65^2)mgH

U_3 = 0.65^3(0.70)(9.81)(1.5)

U_3 = 2.83 J

Now we will have energy loss in fourth bounce given as

Loss = 0.35 U_3

Loss = 0.35(2.83)

Loss = 0.99 J

Part C)

This is loss in terms of thermal energy due to collision with the floor
