Calculating Force air

The action force is the balloon pushing the air out.

What is the magnitude of the reaction force of the air

pushing on the balloon?

N.

= -3N

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

(**i would really appreciate if this was answered soon** ) which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?
