Answer:
<em>The atoms in the hot bodies have higher kinetic energy than those of the cold bodies. Thus to maintain thermal equilibrium, the atoms of higher kinetic energy tries to move and collide with the atoms of low kinetic energy. Thus heat transfers from a hot body to a cold body.</em>

Answer:
Charge on Moon and Earth is 5.43x10¹³ C .
Explanation:
Gravitational force is the force of attraction between any two bodies having mass while Electrostatic force is the force experienced by two charge bodies. Electrostatic force can be attractive or repulsive.
Let M and m be the mass of Earth and Moon respectively, d is the distance between Earth and Moon and q be the charge on Earth and -q be on the Moon.
Gravitational force, F₁ =![\frac{G\times{m}\times{M}}{d^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BG%5Ctimes%7Bm%7D%5Ctimes%7BM%7D%7D%7Bd%5E%7B2%7D%20%7D)
Here G is gravitational constant.
Electrostatic force, F₂ = ![\frac{k\times{q}\times{q}}{d^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Bk%5Ctimes%7Bq%7D%5Ctimes%7Bq%7D%7D%7Bd%5E%7B2%7D%20%7D)
Here k is Coulomb constant.
According to the problem, the gravitational force between Earth and Moon is equal to the electrostatic force between them.
F₁ = F₂
= ![\frac{k\times{q}\times{q}}{d^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Bk%5Ctimes%7Bq%7D%5Ctimes%7Bq%7D%7D%7Bd%5E%7B2%7D%20%7D)
= ![q^{2}](https://tex.z-dn.net/?f=q%5E%7B2%7D)
Put 6.07x10⁻¹¹ N m²/kg² for G, 5.97x10²⁴ kg for M, 7.34x10²² kg for m and 9x10⁹ N m²/C² in the above equation.
= q²
q = ![\sqrt{2.95\times{10^{27} }}](https://tex.z-dn.net/?f=%5Csqrt%7B2.95%5Ctimes%7B10%5E%7B27%7D%20%7D%7D)
q = 5.43x10¹³ C
In 1784, Benjamin Franklin made what may have been the first connection between volcanoes and global climate while stationed in Paris as the first diplomatic representative of the United States of America. He observed that during the summer of 1783, the climate was abnormally cold, both in Europe and back in the U.S. The ground froze early, the first snow stayed on the ground without melting, the winter was more severe than usual, and there seemed to be "a constant fog over all Europe, and [a] great part of North America."

The initial velocity of a car that accelerates at a constant rate of 3m/s² for 5 seconds is 12m/s.
CALCULATE INITIAL VELOCITY:
The initial velocity of the car can be calculated by using one of the equation of motion as follows:
V = u + at
Where;
- V = final velocity (m/s)
- u = initial velocity (m/s)
- a = acceleration due to gravity (m/s²)
- t = time (s)
According to this question, a car accelerates at a constant rate of 3 m/s² for 5 seconds. If it reaches a velocity of 27 m/s, its initial velocity is calculated as follows:
u = v - at
u = 27 - 3(5)
u = 27 - 15
u = 12m/s.
Therefore, the initial velocity of a car that accelerates at a constant rate of 3m/s² for 5 seconds is 12m/s.
