You're in an elevator standing on a bathroom scale. The bathroom scale reads the normal force that it needs to exert on you, upwards. so you stay on top of it. What would the FBD of you look like if the elevator was moving upwards at a constant velocity? FN F₂ LE₂ 1 FN F5 FN F₂ 4

Please help me check if these are correct. To the left of the quest you have a x and an arrow. The x is my answer and the arrow is the correct

A balloon is tied to the floor of a minivan. Currently, the balloon isn't going straight up like normal, but is instead bending towards the
back of the van. This is because....
The van is accelerating forwards (speeding up).
The van is accelerating backwards (slowing down/braking).
The van is at rest.
The vehicle is moving forward at a constant velocity.
The vehicle is moving backward at a constant velocity (reversing).
Usually the balloon in the van would try to go straight up, what is responsible for it going towards the back of the van?

The tension in the string is pushing the balloon backwards.
There is a higher density of air at the back of the van, which causes the helium balloon to be pulled towards the back of the van.
Nothing is forcing it backwards, as the van accelerates forwards the balloon naturally wants to remain where it was in the Earth
frame of reference, according to Newton's first law of motion.
There is a higher density of air at the front of the van, which causes the helium balloon to be pushed away from the front of the
van.
