A box of mass m = 18.0 kg is initially at rest at the bottom of a rough plane that is inclined at an angle of θ = 20.0° above the horizontal. You push horizontally on the box with a constant force Fa that has a magnitude of 115 N. After you have pushed the box 1.50 m up the incline, it is traveling with a speed of 0.800 m/s. What is the coefficient of kinetic friction between the box and the plane?

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

explanation:

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
