Answer:
hange in value is because the observer and the source has a relatively high speed
Explanation:
The emission of a molecular with is always the same, the reason why they change in value is because the observer and the source has a relatively high speed.
As the energy of the beam varies inversely with the wavelength, this shift is due to the fact that the earth and the cloud are moving away from each other.
If we want to find the velocity eta value we must use the relativistic Doppler effect
f ’= fs √ [(1- v / c) / (1 + v / c)]
A. True
It is true that mass is a measure of the quantity of matter in an object.
Explanation:
It is given that,
Mass of the Cadillac,
Speed of Cadillac, (towards north)
Mass of Volkswagen,
The cars stuck together and slid to a halt, leaving skid marks angled 35 degrees north of east.
According to the law of conservation of momentum,
The momentum along x axis, ............(1)
The momentum along y axis, ...........(2)
From equation (1) and (2) it is clear that,
So, the Volkswagen going just before the impact is 8.72 m/s. Hence, this is the required solution.
Explanation:
We know that that the range of the ball on the earth
therefore, range of the ball on moon
therefore,
Therefore, the range of ball will be 6 times on the moon than that on earth
