5. You and your friend are standing in front of a conveyor belt of an airport. The belt moves at a velocity V = 0.8 m/s and it is long l = 200 m. At a given moment, you step on the conveyor belt while your friend
starts walking at a constant pace v = 1.2 m/s.
(a) What is her velocity with respect to you?
(b) How much before you will your friend reach the end of the conveyor belt?

The particles of the gas inside the ball heats up, bouncing off each other and spreading farther apart.hope my answer has you : )

Perhaps seek some professional ? it isn't very asking some children who are just trying to find out answers to homework.also, it seems professional would actually be good to you. obviously it isn't going to magically fix your depression, but it'll do something. drugs, smoking weed, it won't do much, especially if your husband is against it. if you do it he'll dislike it. but talk to him, try and get him to listen to you, and figure everything out together, okay? there's a website- maybe it can offer some ?
