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:
Information
Genes carry the __information___ that determines your traits, which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes.

Answer:
positive reinforcer; negative reinforcer
Explanation:
positive reinforcer; negative reinforcer
Receiving delicious food can be seen as a positive reinforcer while escaping electric shock can be seen as a negative reinforcer.
The force between two charges objects is related to separation.
Draw a vector diagram. The net force on particle 1 = F12 + F13 + F14 These forces have to be added as vectors.
We will resolve our forces along the direction 1-4 F12 (tot) = -kQq / a^2 in the direction of particle 4 F12 = -kQq *sin (45) / a^2 F12 = -kQq /( a^2 * sqrt(2) )
By symetry this is the same as F13 F13 = -kQq /( a^2 * sqrt(2) )
F14 = -kQQ / (Sqrt(2)*a) ^ 2
For net force on particle 1 :
F12+F13+F14 = 0 -2kQq /( a^2 * sqrt(2) ) + -kQQ / (Sqrt(2)*a) ^ 2 = 0
Some simple manipulation should give you :
Q/q = -2 sqrt(2)
