Part B Energy can be created from renewable and nonrenewable resources. Using the table as a guide,
research and evaluate two forms of nonrenewable energy. Use reliable online resources, such as the
US Energy Information Administration (EIA). Describe the following characteristics for each type of
nonrenewable energy:
• how and where it is extracted
benefits
risks it poses to the environment or living organisms
any other interesting information (such as its reliability, aesthetics, and social or cultural impacts)
Record the sources you used for obtaining the information.

When a book falls from a shelf to the ground without anyone pushing on it, no work is done on the book. true or false

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
