To develop this problem we require the concepts related to wavelength and its expression to calculate it.
The wavelength is given by

Where,
light velocity
f = frequency.
Our values are given by,



Then,
Visible
Gamma Ray
Infrared
<em>*Note the designation on the type of rays that are, can be found in consulted via On-line or in the optical books referring to the electromagnetic spectrum table with their respective ranges.</em>
Answer:
a

b
Explanation:
From the question we are told that
The total mass of three people is 
The mass of the car is 
The compression of the car spring is 
Generally the spring constant is mathematically represented as

Here F is the force exerted by the mass of three people and that of the car , this is mathematically represented as
=> 
=> ![F = ([2.0*10^{2} ]+[ 1.200*10^{3}]) * 9.8](https://tex.z-dn.net/?f=F%20%3D%20%28%5B2.0%2A10%5E%7B2%7D%20%5D%2B%5B%201.200%2A10%5E%7B3%7D%5D%29%20%2A%209.8)
=> 
So

=> 
Generally if the mass which the car is loaded with is 
Then the force experienced by the spring is
=> 
=> 
=> 
Generally from the above formula the compression is

=> 
=>
Answer:
True
Explanation:
As the Earth goes around the Sun, it will appear that Earth is stationary and Sun is going around it. One can observe the same in real life as well. This apparent path followed by the Sun is called Ecliptic. The plane consisting Ecliptic is called as Ecliptic plane which is same as the orbital plane of Earth.
All the planets of the Solar system are also going around the Sun. Their orbital plane has negligible tilt with respect to Ecliptic plane. Due to this the planets will always appear near to the Ecliptic as they move on the celestial sphere.
The Earth gets hotter as one travels towards the core, known as the geothermal gradient. The geothermal gradient is the amount that the Earth's temperature increases with depth. ... On average, the temperature increases by about 25°C for every kilometer of depth.
