Answer:
Explanation:
The potential energy of the satellite at the surface of the Earth is:
The potential energy of the satellite in the circular orbit is:
The energy required to put the satellite in the orbit is the difference between the two potential energies:
D. Light as light is a wave
Answer:
50N
Explanation:
Since the floor is frictionless, the net force = mass × acceleration.
given that,
mass = 10kg
and acceleration is 5 m/s²
Thus,
Force = 10 × 5
Force = 50 N
D.) The energy needed to create work.
