Calculate the gravitational force between Jupiter and Pluto if: Jupiter m = 1.9 X 1027 kg

Sun m = 1.3 X 1022 kg

Distance between their two centers of mass is = 5.14 X 109 m

G = 6.67 X 10-11

(To enter Scientific Notation use "e". For example, 6.02 X 1023 would be entered as 6.02e23.)

The speed of light in a material is 0.50 c. what is the critical angle of a light ray at the interface between the material and a vacuum?

Alead ball is dropped into a lake from a diving board 5m above the water . it hits the water with a certain velocity and then sink with constant velocity in bottom . it reaches the bottom 5 second after it is dropped if g= 10m/s2 . find depth of the lake and average velocity of the ball ?

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great.d) about 10 times as great.
