Answer:
A jet plane flying straight and at level at constant speed
Explanation:
The<em> inertial frame </em>of reference is a frame of reference in which all <em>Newton law is valid</em> ie Newton second law of motion and therefore newton first law of motion holds good. <em>The frame of reference does not accelerate.</em>
All the object that is in the frame of reference are at rest or moving with constant rectilinear motion with constant velocity unless acted upon by any force.
The average intensity received on the Earth's surface is 

where R is the distance of the earth from the sun.
![I=4*10^{26}/4\pi *[150*106*10^{3}]^{2}](https://tex.z-dn.net/?f=I%3D4%2A10%5E%7B26%7D%2F4%5Cpi%20%2A%5B150%2A106%2A10%5E%7B3%7D%5D%5E%7B2%7D)


What is the meaning of the intensity of sunlight?
Sun intensity refers to the amount of incoming solar energy, or radiation, that reaches the Earth's surface. The angle at which the rays from the sun hit the Earth determines this intensity.
What is the average intensity received on the Earth's surface?
The average intensity received on the Earth's surface is given by:

Thus, the average intensity received on the Earth's surface is

A simple harmonic motion is defined by the amplitude and angular frequency of the oscillation, which are represented in the given function as 6 units and 98 rad/s respectively.
<h3>General wave equation for simple harmonic motion</h3>
y = A sinωt
where;
- A is amplitude of the motion
- ω is angular frequency
<h3>Amplitude of the oscillation</h3>
A = 6 units
<h3>Angular frequency of the wave</h3>
ω = 98 rad/s
A simple harmonic motion is defined by the amplitude and angular frequency of the oscillation. Thus, the wave is executing simple harmonic motion.
