Answer:
Every object has a different density and therefore carries different properties. When rays of white light strike an object, each ray light strikes the object with different frequency and therefore is absorbed and reflected differently from the host object.
In case if all the frequencies are absorbed by the object, it turns out to be black in color. Whereas on the other hand, if it is a mix of absorption and reflection, it makes different colors based on its frequencies and other properties of the object.
Answer:3N
Explanation:
SUBTRACT THE FRICTIONAL FORCE FROM THE ACTING FORCE
4-1=3
KE=1/2mv^2
So the 3kg ball rolling at velocity of 3m/s has a KE=1/2(3)(3^2)=27/2=13.5J
The 2kg ball only has a KE=1/2(2)(3^2)=9J
So we can see the 3kg ball has more KE than the 2kg ball because they are moving at the same velocity so the bigger mass has more KE
