What capacitance is needed to store 3μC of charge at a voltage of 120V?
katrin [286]

<u>Answer:</u>

 C = 0.025F

<u>Explanation:</u>

Charge =q=3×10^{-6}C

Voltage=V=120V

Q=CV

C=Q/V

   =3×10^{-6}/120

   =1/40×10^{-6}

        C = 0.025F

         C=2.5 10^{-4}C  0r  25 ×10^{-3}F

During a goal-line stand, a 112-kg fullback moving eastward with a speed of 6 m/s
11111nata11111 [884]

Answer:

-1.24 m/s

Explanation:

Total momentum before collision = total momentum after collision

Total momentum before collision = (mass of full back * velocity of fullback) + (mass of lineman * velocity of line man).

Mass of full back = 112 kg, mass of line bag = 120 kg, velocity of full back  6 m/s (east), velocity of line back = -8 m/s (west). Hence:

Total momentum before collision = (112 * 6) + (120 * -8) = 672 - 960 = -288 kgm/s

The total momentum after collision = (mass of full back + mass of line back) * velocity after collision.

Let velocity after collision be v, hence:

The total momentum after collision = (112 + 120)v = 232v

Total momentum before collision = total momentum after collision

-288 = 232v

v = -288 / 232

v = -1.24 m/s

Therefore after collision, the two players would move at a velocity 1.24 m/s west (the same direction as the lineman).

if the displacement of a car was 150 km [E] and the velocity was 15.0 km/h [E], what was the travel time?
soldi70 [24.7K]
Given,
Displacement of the car = 150 km
Velocity of the car = 15.0 km/h

We need to calculate the travel time t

We all know that the formula to calculate velocity is

Velocity = displacement / time

From the above equation,

Time = Displacement / Velocity

Substituting the values in the above equation, 

Time = 150 / 15.0 = 10 hours
Therefore, travel time = 10 hours.
