Release the car and record there time from the photogate at the bottom of the hill. what is the potential energy at the end of the loop? what is the kinetic energy at the end of the loop (based upon the photogate time)? oh also can you help me find the speed of the car at the bottom of the hill like i know speed is distance multiples by time but i don’t know what number to use for distance

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 !

h o h o hope you have a merry christmas!
