Which object has the highest temperature? (see chart below)

object kinetic energy of molecules(j)
a 1.50 x 10^4
b 1.73 x 10^5
c 2.73 x 10^3
d 5.06 x 10^4

answers:
(a)object c
(b)object a
(c)object b
(d)object d

I can't see the chart.

But by kinetic energy theory, the temperature is a measure of the average kinetic energy of the particles.

So a low kinetic energy would depict a low temperature and a high kinetic energy would depict a high temperature.

So from this theory the particle with the highest temperature would be the one with the highest kinetic energy.

And that is by b,  with a value of 1.73 x 10^5 J.

(c)object B

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.
