The drawing shows three particles far away from any other objects and located on a straight line. the masses of these particles are ma = 363 kg, mb = 517 kg, and mc = 154 kg. find the magnitude and direction of the net gravitational force acting on each of the three particles (let the direction to the right be positive).
particle a is 0.5m from b and b is .25m from all in a astraight line

Tall pacific coast redwood trees can reach heights of about 100 m. if air drag is negligibly small, how fast is a sequola cone moving when it reaches the ground f it dropped from the top of a 100 m tree?

Gravity is pulling an object into the sun. the closer the object gets to the sun, the greater the gravitational force that acts on the object, increasing its acceleration. a line graph plotting the speed of the object against time would have which shape? a: straight line of positive slope b: curved line that slopes upward c: curved line that slopes downward d: straight line of negative slope
