The point in the orbit of a planet, asteroid, or comet at which it is closest to the sun.
PART A)
Heat released by iron = heat gain by water
now we have
PART B)
When endothermic changes takes place in the system then system absorbs the energy from its surrounding and keeps on cooling down
Due to this the observer will feel the cool down of the surface temperature and conclude that it is an endothermic reaction
PART C)
When a substance freezes its temperature do not change but if we will check the potential energy of molecules we can conclude that the system released its energy which is known as latent heat.
This will lead to the increase in its potential energy
And due to this decrease in latent heat the substance will freeze
Answer:
The pressure exerted by the girl is 245,000 N/m²
Explanation:
Given;
mass of the girl, m = 50 kg
area of the girl's shoe, A = 0.002 m²
The pressure exerted by the girl is calculated as follows;
Therefore, the pressure exerted by the girl is 245,000 N/m²
I believe this is a true or false question. The answer is true. The reason we have seasons is because of the earths tilt. So without it, we would simply have a constant weather pattern. That's why it can get so cold around the North Pole, the tilt is most drastic there. So the real answer is that it depends on where you live. If you're on the equator, then no, not having a tilt won't impact climate much, but the further you are from the equator, the more change there would be.
