"Inner" planets are usually considered to be Mercury, Venus,
Earth, and Mars.
A). No. None of these planets has any substantial amount of hydrogen
or helium in its atmosphere.
B). No. Mercury and Venus have no moons at all, and Earth and Mars
have only three moons total between them.
C). No. Not sure what this means, but the "ground" seems like a pretty fair
land-atmosphere interface, and Venus, Earth, and Mars have a lot of that.
D). Yes. All four of them have it.
Newton’s second law is F = mass times acceleration.
F divided by acceleration equals her mass.
46/0.834 = 55.156 kg
Answer:
decreases, increases, minimum (zero)
Explanation:
Kinetic energy of a body is directly proportional to the square of velocity of the body and the potential energy is directly proportional to the height of the body at which it is placed.
The formula for the kinetic energy is
K = 1/2 m v^2
The formula for the potential energy is
U = m g h
As the body goes up its kinetic energy decreases as the velocity of the object decreases.
As the body goes up the potential energy increases as the height increases.
At the top most point, the velocity of teh object is zero, so the kinetic energy at the top is zero.
Answer:
Explanation:
Mass of the Sun, 
The radius of the Sun, 
We need to find the acceleration due to gravity on the surface of the Sun. It is given by the formula as follows :
So, the value of acceleration due to gravity on the Sun is 
.
