There are only two types of planetary motion and these kinds are revolution and rotation. Revolution is the act of the planets in the solar system to move around or "revolve" around the sun while rotation is done in which the planet "rotates" on its axis. In addition, the earth revolves around the sun in 365 and 1/4 days.

Answer: Planetary motion refers to the type of motion in which a planet moves. Different planets have different planetary motion, with variation in their speed and moving direction.

The different types of planetary motion are as follows-

<u>Rotation-</u> Every planet rotates around its own axis. This rotational speed is different for different planets. Some of them rotates in clockwise and some in anticlockwise direction. For example, earth rotates about its axis at nearly 24 hours.
<u>Revolution-</u> Every planet revolves around the sun. The time required by planets to complete one revolution again differs from planet to planet. The inner planets because of its smaller radius takes lesser amount of time to make one complete rotation, in comparison to the outer planets. For example, earth completes one revolution in 365.5 days.

What is rotation and revolution

skad [1K]

When an object turns around an internal axis (like the Earth turns around its axis) it is called a rotation. When an object circles an external axis (like the Earth circles the sun) it is called a revolution.

Explanation:

We need 2 different equations for this problem: first the velocity of sound equation, then the frequency of the sound equation.

The velocity of sound is found in:

v = 331.5 + .606T

We need to find that first in order to fill it into the frequency equation which is

$f=\frac{v}{\lambda}$ where v is the velocity we will find the part a, f is frequency and lambda is the wavelength. Starting with the velocity of the sound:
