Answer:
No machine is free from the effects of gravity, and even with wonderful lubrication, friction always exists. The energy a machine produces is always less than the energy put into it (energy input). ... That is why 100% efficiency in machines shall not be possible.
Answer:Net Force is zero
Explanation:
Given
Car is moving to the left with constant velocity i.e. net force on the car is zero
because change in velocity with respect to time is acceleration thus force is also zero because net acceleration is zero
Mathematically
acceleration
as velocity is constant therefore 
thus a=0 , F=0

The distribution of the fossil fuel depends on the factors like land, temperature, altitude and so on. Because of the difference in all these factors in different areas, there is unequal distribution of fossil fuels.
<u>Explanation:</u>
The problem of allocation of resources arises due to the scarcity of resources, and refers to the question of which wants should be satisfied and which should be left unsatisfied. Because of the scarcity of resources in some areas, there is low production and therefore low growth in that area.
Most natural resources, including fossil fuels, are not distributed evenly around the Earth. Deposits of fossil fuels depend on the climate and organisms that lived in that region millions of years ago, and the geological processes that have since taken place.
Answer:
Benjamin
Explanation:

They were given conditions that in case they were to go back, they should come back with their brother Benjamin.
