75km=75000m
35min=2100 seconds
Velocity=Displacement/Time
=75000/2100
=750/21
=35.71 m/s
I believe this is it
The centripetal force is given by
F = mv^2 / r
When v' = v/2,
F' = mv'^2/r = m(v/2)^2/r = mv^2/4r = F/4.
So the centripetal force is divided by 4.
Answer:
The amount of heat or moisture in the air
Explanation:
Or a switch
Answer:
I think the answer is As the Earth shakes at the surface, seismic waves are pulsing through the layers of Earth below, invisible to human eyes and ears but observable as sound waves. Sound waves that can be recorded, even monitored, to provide advance warning of a coming seismic event.
