Time period of any moon of Jupiter is given by
from above formula we can say that mass of Jupiter is given by
now for part a)
T = 1.77 day = 152928 seconds
now by above formula
Part B)
T = 3.55 day = 306720 seconds
now by above formula
Part c)
T = 7.16 day = 618624 seconds
now by above formula
PART D)
T = 16.7 day = 1442880 seconds
now by above formula
Usually, the forces that start the oscillation of buildings are the wind and microearthquakes.
The power dissipated across a component can be calculated through the formula P=I^2xR
Substituting the values in we get P=(0.5)^2x10=2.5W
The middle one on the list is the correct one.
The first one ... distance divided by time ... is Speed, not force.
The third one ... mass times velocity ... is Momentum, not force.
