Which of the following is true about two objects of the same mass when they have a non-sticky collision?

a. when the objects collide, the momentum of each will become zero

b. when the objects collide, they will trade velocities

c. when the objects collide, each object will then have the sum of the original momentum’s

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the volume increases

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
