PLEASE HELP ME
1.65 m long broom is being used to sweep away some dirt. The brush is moving the dirt with 4.30 N of force. The person’s hand is 0.55 m from the top of the broom (which is the fulcrum).

a. What force does a person have to apply to sweep the dirt?
b. What is the broom’s ideal mechanical advantage?

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

truck y has a greater velocity than truck x.
