Travka [436]

Mechanical Energy = PE + KE

PE: mgh = 200 x 9.8 x 18 = 35280

PE: 35280 Joules

KE: 1/2mv^2 = 1/2 x 200 x 16^2 = 25600

KE: 25600 Joules

ME: 35280 + 25600

ME: 60,880J

Which is true concerning the acceleration due to Earth's gravity (ge) ? It decreases with increasing altitude. B. It is differe
klasskru [66]

Answer:

Option A decreases with increase in altitude

Explanation:

This can be explained as the value of gravitational acceleration, 'g' is not same everywhere.

It has its maximum value at poles of the Earth and minimum on its equator.

Thus a person will weigh more at poles than equator.

This variation is in accordance to:

g = \frac{GM_{E}}{radius^{2}}

Thus the gravitational acceleration changes as inverse square of the Radius of the Earth.

Thus as we move away from the Earth's center, gravitational acceleration, g decreases.

From what three regions do most of the small objects in the universe come?
Ivenika [448]

Answer:

Scientists who study the Sun usually divide it up into three main regions: the Sun's interior, the solar atmosphere, and the visible "surface" of the Sun which lies between the interior and the atmosphere. There are three main parts to the Sun's interior: the core, the radiative zone, and the convective zone.

Explanation:

Hopefully this helps :)
