If you know that the radius of the Earth is 6.38 X 10^6 m and the value of the constant G is equal to 6.67 X 10^-11 Nm^2/ kg^2 and the acceleration of gravity 9.8 m/s^2 then calculate the mass of the Earth?

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.

answer: a. same unit

explanation:

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
