The greatest variation in size, mass, and luminosity occurs in elliptical galaxies.

<h3>What is Variation?</h3>

This is defined as the difference from the norm which is exhibited by objects.

In the solar system, variation in features such as size, mass, and luminosity occurs mostly in elliptical galaxies due to presence of array of stars thereby making it the most appropriate choice.

An airplane travels at 950 km/h. how long does it take to travel 1.00 km
Reptile [31]
First calculate the <em>percentage of one hr</em> it takes. You can do this by dividing the distance by the velocity. The general formula for this is:

D = v *t

always remember to make sure your units are the same.

so that's 1km by the 950km/h velocity.

1/950 = 0.0010526 hrs

Then multiply that answer by 3600 (<em>the number of seconds in 1 hr</em>) to find how many seconds this is.

0.0010526 * 3600 = 3.789 seconds
