Answer:
0.057 joules is needed to create the total rotational energy each second.
Explanation:
The energy rate is the ratio of total energy to time, which coincides with the definition of power at constant rate:
0.057 joules is needed to create the total rotational energy each second.
Answer:
The weight of the landing craft in the vicinity of Callisto's surface is 3480 N.
Explanation:
The engine of the craft provides an upward thrust of so that the space craft descends at a constant speed.
This implies that the net force on the space craft is zero.
The upward thrust will be equal to the downward gravitational pull by Callisto.
So the weight of the craft near the vicinity will be 3480 N.
