The graph shows the acceleration of the cart with three
different fan speeds. the fan provides the force
necessary to accelerate the cart.
as the fan speed increases, the acceleration of the cart
the type of relationship that exists between the force
applied to the cart by the fan and the acceleration of
the cart is
relationship.

Explanation:

We know that the rate of change of velocity is called acceleration of an object. Its expression is given by :

The force acting on an object is the product of mass and acceleration. It is given by :

F = ma

It is clear that as the fan speed increases, the acceleration of the cart increases. Also from the Newton's second law of motion, the force  applied to the cart by the fan and the acceleration of the cart has direct relationship.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
