Answer:
the relativistic Doppler effect,
Explanation:
The emission of 21 cm from hydrogen atoms suffers from the relativistic Doppler effect, this is a current of its wavelength due to the relative speed between the source and the observer, us located on Earth.
If the object is moving away from us the shift is towards red and if the body is approaching towards us the shift is towards blue.
Also the value of the shift depends on the speed of the body.
Answer:
Energy is:
A property that must be transferred to perform work.
Answer:
The position of the spring in terms of g, m & k is
Explanation:
Stiffness of the spring = k
Mass = m
When a mass m is attached with the spring then spring stretched. in that case the force exerted on the spring is equal to weight of the mass attached.
⇒ Force exerted on the spring F = k x
⇒ m g = k x
⇒
This is the position of the spring in terms of g, m & k.
