Science Final Study Guide?
My teacher gave us a packet of 300 questions to help us prepare for the final. But he isn’t going over it with us, so it’s up to us to get the right answer. I can’t find the right answer to the following questions..
Solar cells convert what type of energy into electrical energy?
If no friction acts on a diver during a dive, then which of the following statements is true?
A) The total mechanical energy of the system increases
B) Potential energy can be converted into kinetic energy but not vice versa.
C) (KE+PE)beginning = (KE+PE)end
D) All of the above
What is biomass energy?
Ah, man there is so many more, I can’t even type all of them out. This is going to take me forever.
Any help is appreciated.
Please, no bullcrap answers.
answer to #1 is solar energy
answer to #2 is d
the answer to question #3 is Energy produced by combusting biomass materials such as wood. The carbon dioxide emitted from burning biomass will not increase total atmospheric carbon dioxide if this consumption is done on a sustainable basis (ie, if in a given period of time, regrowth of biomass takes up as much carbon dioxide as is released from biomass combustion). Biomass energy is often suggested as a replacement for fossil fuel combustion.
hope this helps
