red goes to red, black goes to white, yellow goes to green, blue goes to blue.
the axis acts against and it would be a contact force
Explanation:
sinces : Momentum = velocity × mass
then : 30 = 10 × m and m = 30 ÷ 10 = 3 kg
Answer:
58.44 C
Explanation:
Electric field is found by
Therefore, the charge is
Therefore, required charge is 58.44 C
Answer:
20000 W
Explanation:
Power: This can be defined as the rate at which energy is dissipated or used. The S.I unit of power is Watt(W).
The expression of power is given as,
P = E/t.............................. Equation 1
Where P = power, E = Energy, t = time.
Given: E = 200 J, t = 0.01 s
Substitute into equation 1
P = 200/0.01
P = 20000 W.
Hence the average power = 20000 W
