Two sustainability challenges you would face when developing a sustainable food supply for a Martian colony would relate to Martian radiation and soil characteristics.
According to experiments carried out, Martian radiation is about 17 times more intense than on Earth, which impacts vegetation growth and crop quality.
Therefore, it is necessary to develop resources that enable a sustainable food supply in remote locations, such as for a Martian colony, as some production challenges may be related to food resistance and the amount of oxygen and water needed for growth.
Some solutions, therefore, could be planting in an underground shelter, which would be a controlled environment where conditions would be more favorable for the production of food with greater quality and diversity.

Momentum is conserved after the collision
Momentum of 2 Kg before collision = 2 * 3 = 6
Momentum of 4 kg before collision = 4 * -3 = -12
so 6 + -12 = 2 * -4 + 4 *x where x is velocity of 4kg marble.
4x - 8 = -6
4x = 2
x = 0.5
Velocity of 4 kg marble is 0.5 m/s after collision
The 2 kg marble will move in the opposite direction to which it was moving before the collision.
Answer:
Output power = 500 KW
Explanation:
Given the following data;
Efficiency = 20%
Input power = 2500 KW
To find the output power;
Substituting into the equation, we have;
LET Output power = OP
Cross-multiplying, we have;
Output power = 500 KW
Answer:
yes
Explanation:
because when you slow down, the resistance slows with the speed.
