Answer:
given,
children on left shore pulls the rope by 3 N
Children on the right shore pulls the rope by 2 N
speed of the box = 3 m/s
a) Power = Force x Velocity
Power = 3.0 N * 3
Power = 9 Watt
Power = 2.0 N x 3
Power = 6 Watt
b) Net Force = 3.0 N - 2.0 N = 1.0 N
Net Power = 1.0 x 3 Watt
Net Power = 3 Watt
c) net force is acting on the box and at an instant velocity is given so, when the body moves it will accelerate and velocity will change so, the value of part A and B will also change
Answer:
Train will take 156 sec to travel 12km.
Answer:
Glad you asked that!
Explanation:
Actually,no.You see,if the earth was perfectly straight,then the northern hemisphere and southern hemisphere would have the same seasons,which is pretty much the world.But our world is tilted,so we happen to have differences for southern hemisphere and northern hemisphere.
