Hiroshima had 46 kg of Uranium dropped on it. Chernobyl had 180 tons of reactor fuel plus nuclear waste. Explain the difference in the toxic levels of radiation and why the drastic difference in the treatment of the two sites.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

it would be c. predictability
