At certain altitude, the temperature of air decrease, The air becomes saturated and water vapour molecules starts condensing.
As the altitude of air increase, the atmospheric pressure decrease due to which the temperature of the air decrease. The water molecules in the atmosphere start condensing, which saturate the air (that is air can no hold water molecules), due to which the water vapour molecules starts condensing and falls on the earth in the form of rain.
Friction causes kinetic energy to be converted into thermal energy.
Friction causes kinetic energy to be converted into thermal energy, among other forms of energy. When an object is in motion and experiences friction, the work done by friction is negative, which reduces the object's kinetic energy. This converted energy is often released as heat.

C. Light can pass through Object B faster than it can pass through Object A.
D. The optical density of Object B is higher than the optical density of Object A.
The correct answer is
C. Light can pass through Object B faster than it can pass through Object A.
In fact, the index of refraction of a material is defined as:
where c is the speed of light in vacuum and v is the speed of light in the material. Rearranging the equation, we can write the speed of light in the material as:
So we that, the smaller the refractive index n, the greater the speed of light in the material, v. In this problem, object B has lower refractive index than object A, so light travels faster in object B.
c. has strong, spinning winds
b. has warm, calm air and light winds
d. has spiraling bands of heavy rain
Answer:
Explanation:
The eye of a hurricane is calm and "peaceful", it's the region with calm weather. But the eyewall is really dangerous, due to its pressure and speed difference. Actually, the eyewall has the most severe winds and weather. Another important characteristic is that the eye has the lower pressure.
So, among the options, b. is the right answer.
b. has warm, calm air and light winds
b. It is a theory which is not supported by data.
c. It is an observation which cannot be explained.
d. It is a description which does not work under similar conditions.
