Answer:
P = 3800 W
Explanation:
Power is equal to energy divide by time P = E/t
plug in 4560000 J for energy
convert 20 minutes to seconds
20 * 60 = 1200 seconds
plug in 1200 seconds for time
P = 4560000/1200
P = 3800 W
V=IR can be changed to V/R=I so 10V/2 ohms = 5amps so 5 amps is your answer boss
The answer is 18000 kgm/s
Momentum is mass times velocity so just do 750•24.
Answer:
Let M1 = 8 kg and M2 = 34 kg
F = M a = (M1 + M2) a
F = M2 g the net force accelerating the system
M2 g = (M1 + M2) a
a = M2 / (M1 + M2) g = 34 / (42) g = .81 g = 7.9 m/s^2
