When water vapor condenses during the formation of clouds, energy is released into the atmosphere through the process of latent heating.
Huge amounts of solar energy are absorbed during the evaporation process. There is no thermal equilibrium in protostars. They emit radiation that causes them to lose energy, but their interior temperatures aren't hot enough to start nuclear fusion to replenish the energy. They consequently tighten and warm up. Fusion can replace the energy they are losing once they are heated enough on the inside (about 107 K). The gas atoms start to collide more and get closer together as the cloud gets smaller, which warms them up. The cloud keeps shrinking and heating up until the force of gravity is balanced by the pressure from the heat.

Answer:
Maximum Tension=224N
Minimum tension= 64N
Explanation:
Given
mass =8 kg
constant speed = 6m/s .
g=10m/s^2
Maximum Tension= [(mv^2/ r) + (mg)]
Minimum tension= [(mv^2/ r) - (mg)]
Then substitute the values,
Maximum Tension= [8 × 6^2)/2 +(8×9.8)] = 224N
Minimum tension= [8 × 6^2)/2 -(8×9.8)]
=64N
Hence, Minimum tension and maximum Tension are =64N and 2224N respectively
First, calculate for the distance between the given points A and B by using the equation,
<span> D = sqrt ((x2 – x1)2 + (y2 – y1)2)</span>
Substitute the known values:
<span> D = sqrt((9 – 2)2 + (25 – 1)2)</span>
<span> D = 25 m</span>
I assume the unknown here is the time it would require for the particle to move from point A to B. This can be answered by dividing the calculated distance by the speed given above.
<span> t = (25 m)/ (50 m/s) = 0.5 s</span>
<span>Thus, it will take 0.5s for the particle to complete the route. </span>
