What type of force are you exerting when you lie on a bed

The force of the weight

Explanation:

When we are lying on the bed, our weight is distributed along of our body and the equivalent of the force is given by the following expression.

w = m*g

where:

m = mass [kg]

g = gravity acceleration [m/s^2]

w = weight of the body [N]

At the moment when we are sleeping our body is at equilibrium, because the mattress is exerting a force with the same amount of the weight but in the opposite direction.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
