Which statement is true? a. the earth has a stronger gravitational pull than the sun because it’s smaller in mass b. planets would travel in a straight line if it weren’t for the force of the suns gravity c. the suns gravitational pull is weaker on planets that are closer to it d. the elliptical path of planets is described by newton’s 1st law of motion

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.

Aforce of 8,480 n is applied to a cart to accelerate it at a rate of 26.5 m/s2. what is the mass of the cart?
