Red dwarfs include the smallest stars commonly weighing between 0.075 to 0.50 percent the mass of the sun, their small size means they burn at a slower rate meaning a dwarf star is to long exceed the life of the universe, their reduced mass also means their surface is very cool
Answer:
doubled
Explanation:
<u>Step 1</u>. Linear momentum (p) = mass X velocity = mv
p = mv -----equation 1
<u>Step 2</u>. if the mass is now twice and speed is same
p = (2*m)v -----equation 2
solving equation 1 and 2 together,
p = mv = 2mv
p = 2
Therefore, its momentum is doubled
