Think about 29.1 you're playing with two of the cards (each with mass m) that you used in activity 27a. initially, these two carts are moving toward each other with the same initial speed vi along the track. the carts collide and the result is one of these final states: (a) assume that the carts hit each other and stop so that the final state of the system has both carts just sitting still (not moving). draw a momentum chart for this situation. make a separate row for each cart. (b) assume that the carts bounce o↵ each other so that the final state of the system has each cart moving opposite to its initial motion but with their speeds unchanged. draw a momentum chart for this situation. (c) as in (b), assume that the carts bounce o↵ each other but now assume that the final speeds are smaller than the initial speeds, equal and in opposite directions. draw a momentum chart. (d) for each case above, does the total momentum of the system that contains the two carts change

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

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
