Answer:
Mass = volume x density. Volume(2) = 1/3, density is 1/4, so
Mass = 1/3 * 1/4 = 1/12 that of Earth.
Surface gravity = m /r^2 = 1/12 / (1/4)^2 = 1/12 / 1/16 = 16/12 = 4/3 Earth’s
So… surface gravity would by 13 m/s^2 vs. 9.8m/s^2
Someone able to jump up 1.5m vs. 9.8m/s^2 is imparting 5.4 m/s of velocity on themselves. Imparting 5.4m/s of velocity on yourself against 13m/s^2 gravity, you would reach 0 velocity at:
1.12m in height.
Answer:
v = 2.94 m/s
Explanation:
When the spring is compressed, its potential energy is equal to (1/2)kx^2, where k is the spring constant and x is the distance compressed. At this point there is no kinetic energy due to there being no movement, meaning the net energy in the system is (1/2)kx^2.
Once the spring leaves the system, it will be moving at a constant velocity v, if friction is ignored. At this time, its kinetic energy will be (1/2)mv^2. It won't have any spring potential energy, making the net energy (1/2)mv^2.
Because of the conservation of energy, these two values can be set equal to each other, since energy will not be gained or lost while the spring is decompressing. That means
(1/2)kx^2 = (1/2)mv^2
kx^2 = mv^2
v^2 = (kx^2)/m
v = sqrt((kx^2)/m)
v = x * sqrt(k/m)
v = 0.122 * sqrt(125/0.215) <--- units converted to m and kg
v = 2.94 m/s
The wind direction changed from morning to night because land and water absorbing solar energy unequally.
<h3>Convection current</h3>
Convection is said to occur when there is heat transfer by an actual movement of participles from place to place. The movement of air mass (wind) is affected by the relative amounts of solar energy absorbed by the land and sea.
Hence, the wind direction changed from morning to night because land and water absorbing solar energy unequally.

Answer:
C. Jupiter
Explanation:
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.
