Steam enters a cylinder—- A
Explanation:
Velocity = displacement / time
v = √((58 m)² + (135 m)²) / (12 min × 60 s/min)
v = 0.20 m/s
20 ohms in parallel with 16 ohm= 8.89
20x16/20+16. Product over sum
Answer:
Torque on the rocket will be 1.11475 N -m
Explanation:
We have given that muscles generate a force of 45.5 N
So force F = 45.5 N
This force acts on the is acting on the effective lever arm of 2.45 cm
So length of the lever arm d = 2.45 cm = 0.0245 m
We have to find torque
We know that torque is given by 
So torque on the rocket will be 1.11475 N -m
a) PE=mgh=0.2*9.8*1.2=2.352 J
b) KE=PE=2.352 J
c)
m/s
