I want to say its cooled by reflection because of the foil, sun reflects off of the foil back into the atmosphere. I don't think it's conduction because I have the foil on my windows and it's never warm to the touch. it's not a liquid so I don't believe it's convection. The foil reflects the radiation so I don't think it's b, c or d. so I wanna say A but I'm not 100% sure
GPE= height x mass x gravitational field strength
5 x 10 x 9,8=490J
Answer:
D
Explanation:
its mass would be the same
because the mass of an object is constant or its independent of the gravitational force or pull
Answer:
<u><em>Frictional force refers to the force generated by two surfaces that contacts and slide against each other.</em></u>
