Describe what happens to particles of matter as you cool the matter to absolute zero (OK). In your description, be sure to explain the changes in kinetic energy and
particle motion

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

inverse v=i*r
