Explanation:
The combination of the earth's weak gravity and its closeness to the sun does not allow it to hold hydrogen and helium gases in its atmosphere. Its relative closeness to the sun means it is hot enough such that the helium and hydrogen molecules would have high kinetic energy. Remember that gravity acts strongly on larger masses, therefore it would require very strong gravity to have an influence on lighter gas molecules like hydrogen and helium let alone when they have a high kinetic energy. This means these molecules can easily escape the earth’s atmosphere into space.
Planets that are larger (meaning they have a stronger gravity) and farther from the sun (meaning these molecules won't have a very high kinetic energy) are able to hold these lighter gases in their atmosphere. Examples of such planets are Jupiter.

The momentum of the bumper car after the collision is 1,040 kgm/s.
<h3>
Momentum of bumper</h3>
The change in momentum of the bumper is calculated as follows;
P = v(m1 + m2)
P = 8(55 + 75)
P = 1,040 kgm/s
The momentum of the bumper car after the collision is 1,040 kgm/s.
The direction is still the same.

Explanation:
The ratio of the weight of corn to the weight of water consumed will be the same. Either we compare the total weights for the total amount of corn or we compare only a small proportion of it. So, we consider the given 25 kg of corn. So, the mass of corn is given:
m₁ = mass of corn = 25 kg
Now, for mass of water, we will use its density:
ρ₂ = m₂/V₂
m₂ = ρ₂V₂
where,
m₂ = mass of water = ?
V₂ = Volume of water consumed by 25 kg corn = 20 m³
ρ₂ = density of water = 1000 kg/m³
Therefore,
m₂ = (1000 kg/m³)/(20 m³)
m₂ = 50 kg
Now, we calculate the ration:
