2) A simple machine requires 8.3 N of force to obtain an output force of 32 N. What is the
mechanical advantage of the machine?

The mechanical advantage of the machine is 3.9.

Explanation:

A simple machine is a machine which gives the output if we give the required input, and so the output always depends on the input force. Sometimes machines can also reduce the input force to get the required output and the ratio of output to input force is called as the mechanical advantage.

MA =

Here F₀ , output force = 32 N

, input force = 8.3 N

MA =

     = 3.9

So the mechanical advantage of the machine is 3.9.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
