In the lab, you looked at speed-time graphs to determine the acceleration of the cart for each of the three fan speeds.
what was the acceleration of the cart with low fan /s2
what was the acceleration of the cart with medium fan /s2
what was the acceleration of the cart with high fan /s2

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

the answer is a. hope this .
