1. How fast does an object need to travel to stay in orbit for one second? 2. How fast does an object need to travel to stay in orbit for two seconds?
3. How fast does an object need to travel to stay in orbit for three seconds?
4. You may have noticed that the object needs to keep going faster and faster to stay in orbit. What is the average acceleration needed for the object to stay in orbit from 1–3 seconds?
5. In the real world, orbiting objects such as satellites do not need to be constantly accelerating. What is different about real-world satellites and the theoretical satellites?

i belive it is d. both a and c

hope this

mark me branliest, only got   it 1

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!
