Earth rotates about this axis once each day (approximately 24 hours)
and revolves around the sun every year ..
Hope this helped ! :)
Haven't done one like this in awhile but I see no one is answering so I gave it a try. I think it's right but let me know if you see something fishy...
F = ma
F = applied force in newtons = to be determined
m = mass of the car = 2,500 kg
a = acceleration of the car = 3.5 m/s²
F = (2,500 kg)(3.5 m/s²)
F =8750
Answer:
2.When they reach the bottom of the fall
Explanation:
The potential energy of the waterfall is maximum at the maximum height and decreases with decrease in height. Based on the law of conservation of mechanical energy, as the potential energy of the water fall is decreasing with decrease in height of the fall, its kinetic energy will be increasing and the kinetic energy will be maximum at zero height (bottom of the fall).
Thus, the correct option is "2" When they reach the bottom of the fall
