HISET Exam Questions and Answers-
Science
What allows the cells of an organism to use carbon from the enviornment? - Answer-Photosynthesis
During photosynthesis in plants, what is the source of the carbon in the sugar molecule? - Answer-
carbon dioxide in the air
Change of phase is a process whereby matter changes form (solid, to liquid, to gas). What constitutes
this phase change? - Answer-candle melting, ice being boiled
Newtons law of motion provides that an object set in motion remains in motion unless a force acts upon
it. If you suspend a ball from a tree with a piece of string and make it swing, the ball will swing for a
while, then slow down and stop. Why does the ball stop swinging? - Answer-because energy of motion
is converted to heat through friction with the air.
Give facts about gravity. - Answer-1.) the more massive two objects are, the greater the gravitational
force is.
2.)People can jump higher on the Moon than on Earth because the gravitational force between them.
3.)Gravitational force between two objects depends on the distance between them.
Two positively charged objects will ________ - Answer-repel each other
