## anonymous one year ago 10 MEDALS FAN AND TESTIMONY! A softball is hit high into the air. As it rises, the softball A) loses kinetic energy and loses potential energy. B) loses kinetic energy and gains potential energy. C) gains kinetic energy and gains potential energy. Eliminate D) gains kinetic energy and loses potential energy.

I need help on a few of them. There easy but i just don't know them.

2. anonymous

"A" sounds more right

3. anonymous

what do you think

4. anonymous

I was thinking B

5. anonymous

it could also be so it would be a or b

6. Rushwr

I agree with u @ItsKoreyyy !!!!!

7. anonymous

Ok so b? I have a few i need help on :)

8. anonymous

sure

Energy is transferred in solids by conduction, which means that A) heat travels in both directions. Eliminate B) heat travels from the cooler object to the hotter object. C) heat travels from the hotter object to the cooler object. D) heat does not travel between objects of different temperatures.

"C"

$Kinetic energy = \frac{ 1 }{ 2 } mV ^{2}$ When it goes up the velocity reduces thus the kinetic energy decreases. $Potential energy = mgh$ When going up the height increases so the potential energy increases. !!!!

Do you guys do k12

13. anonymous

yes

15. Rushwr

Yeah I agree with u @1Lasandra

sang lol im in 8th and here is my next question During the day, the temperature of the sand in a desert rises as the sand is heated by the sun. After the sun sets, the sand cools. What happens to the heat energy in the sand as it cools? A) It is destroyed. B) It is used by the sand to do work. C) It goes back into the sun, completing the cycle. D) It is transferred to the air via the process of radiation.

19. anonymous

"A"

20. anonymous

A?

21. Rushwr

Heat energy cannot be destroyed. So that's wrong so I will go with D

22. anonymous

Ok can you help on more?

23. anonymous

An example of mechanical energy being converted into heat energy is A) the sun. B) a generator. C) a Snickers bar. D) rubbing your hands together.

24. Rushwr

I think it should be D

25. Rushwr

its obviously not sun !!! Generator converts mechanical energy into electrical energy.

26. anonymous

Lol ok. only a few more!
