And object has mass, so if moving, has a momentum value.
The unit used to measure wavelength is a Nano-meter
Answer:
they stay shifted the same amount to the red
Explanation:
Redshift is given by

Where,
= Wavelength observed
= Wavelength emitted
Also
Transverse redshift is given by

v = Velocity of object
c = Speed of light = 
So, if the velocity is constant the redshift remains the same
Answer: turns to gas
Explanation:
when a liquid gets heated up the chemicals start to boil/evaporate turning the liquid into a gas
The correct answer is Matter is made up of atoms and has mass.
