Frictional force between the object and the floor=5 N
Explanation:
power= 50 W
velocity= 10 m/s
power= force * velocity
50=F * 10
F=50/10
F=5 N
Thus the force of friction= 5 N
Velocity, direction, or both at the same time.
Weight = mass * gravity = 60 kg * 3.75 m/s² = 225 N

Answer:
the primary coil current produces a magnetic field, which changes as the current changes. the iron core increases the strength of the magnetic field. the changing magnetic field induces a changing potential difference (voltage) in the secondary coil.
Answer:
Explanation:
Initial potential energy of the given spacecraft is given as
so we have
so we have
now total work done to move it to infinite is given
W = 0 - U
