calculate the magnitude of the net force on a 4.5 kg mass if the mass moves straight up at constant speed

0

Explanation:

as Newton 1st Law said that every object will remain at rest or in uniform motion (constant speed) in a straight line unless compelled to change its state by the action of an external force

Net Force = 0

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 !
