Press and hold down the "Fn" button while pressing the "Home Prt Sc" button above the numeric keypad to capture the entire screen. Make a screenshot of the active window only by holding down the "Fn" and Alt" keys while pressing "Home Prt Sc." 2. Press the "Start" button, and type "Paint" into the search box.
Answer:
well, as long as there are no right or wrong answers, don't:
look to closely at the screen, as it may mess up your eyes
hold a drink above the computer, as it may spill and cause "sticky keys"
go to sites that you know will give your a computer a virus, cause they cost hundreds of dollars to repair, and some aren't able to come out
go on illegal sites/do illegal operations to the computer itself, because then you won't have a computer

Answer:
D. 4x as much
Explanation:
The answer is pretty simple. The question is asking about 10m/s and 20m/s right? Take a look at the energy at each point on the graph. At 10m/s the kinetic energy is 100 on the graph. At 20m/s the kinetic energy is 400. You'll notice that 100 x 4 is 400 - That's the answer.
You can also prove this mathematically. The formula for kinetic energy is
The question says: constant mass so we can ignore that for now.
(1/2) * 10^2 is (1/2) * 100 = 50
for the 20m/s ball it would be
(1/2) * 20^2 = 400 * 1/2 = 200
Once again, you see that it is 4x
