write an experiment to show that black surfaces absorb heat energy more than shiny polished surfaces or white surface​

One example of an experiment you can do is find out the heat difference between a white car and a black car using the sun in a hot day.

Explanation: The black car would absorb more heat from the sun and would make the inside of the black car hotter than the white car.

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
