What equations would you use to find force?

F = m x a

Explanation:

F=force

m=mass of an object

a=acceleration

It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied. If the same force is applied to two objects of differ- ent mass, the heavier object has less acceleration than the lighter object (Figure 1).

Explanation:

Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.

I hope I helped ^^ have a nice day

i think the answer is b

vapour or gas assuming atmospheriv pressure
