If one object has a large redshift and another object has a small redshift, what can we conclude about these two objects?
a. the one with the large redshift is moving toward us faster than the one with the small redshift.
b. the one with the large redshift is moving away from us faster than the one with the small redshift.
c. the one with the large redshift is moving away from us, and the one with the small redshift is moving toward us.
d. the one with the large redshift is hotter and therefore is putting out more radiation.

b. The one with the large redshift is moving away from us faster than the one with the small redshift.

Explanation:

  From Doppler effect ,If object is moving away from the observer then the spectral lines will shift towards the red part and this is known as red shift.The wavelength of red light is more as compare to the wavelength of blue light.If object is moving towards the observer then the spectral lines will shift towards the blue part and this is known as blue shift.

If the object have  red shift it means that it is moving away from us and if have  large red shift as compare to the other then large red shift object is moving fast as compare to small red shift object.

b. The one with the large redshift is moving away from us faster than the one with the small redshift.

b. The one with the large redshift is moving away from us faster than the one with the small redshift.

Explanation:

A redshift is a sign that the object is moving away.

This is because when an object is moving away from us, the wavelength of the light that it sends our ways, gets "stetched" so it seems to have a longer wavelength. This is a phenomenon known as the Doppler effect.

And longer wavelengths are asociated with red colours, thus it is said tht it has a redshift.

The larger the redshift, the fastest the object is moving away from us.

Thus an object with larger redshift moves away faster (as the option B points out) than an object with small redshift.

But since they both have a redshift, they both are moving away from us.

the answer is

b. The one with the large redshift is moving away from us faster than the one with the small redshift.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
