Two 0.50-kg carts, one red and one green, sit about half a meter apart on a low-friction track. You push on the red one with a constant force of 4.0 N for 0.17 m and then remove your hand. The cart moves 0.33 m on the track and then strikes the green cart. a. What is the work done by you on the two-cart system?b. How far does the system's center of mass move while you are pushing the red cart?c. By what amount does your force change the kinetic energy of the center of mass of the system?

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
