Krista is playing tennis at the park. when the tennis ball flies toward her, krista hits the ball with her racket, which causes the ball to fly in the opposite direction.

according to newton's third law of motion, which of the following is true?
a.
when the racket hits the tennis ball with a force, the ball applies an equal force in the same direction as the racket's force.
b.
when the racket hits the tennis ball with a force, the ball applies a much weaker force in the opposite direction of the racket's force.
c.
when the racket hits the tennis ball with a force, the tennis ball applies an equal but opposite force to the racket.
d.
when the racket hits the tennis ball with a force, the ball does not apply any reaction force to the racket.

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.

If a spring has a k value of 100 newtons per meter and it is stretched 0.50 meters, what is the restoring force of the spring?

Which statement correctly describes the current in a circuit that is made up of any two resistors connected in parallel with a battery? a. the current in the battery and in each resistor is the same b. the current the battery equals to the sum of the currents in the resistors c.the current in the battery is less than the current in either resistor d. the current in the battery equals to the product of the currents in the resistors
