The diagram below depicts two cases in which a 0.2 kg ball strikes falls
and strikes the ground. Case A: the ball is moving downward at 5 m/s
when it hits the ground then rebounds upward at 2 m/s. Case B: The ball
moving downward at 5 m/s when it hits the ground and stops
immediately. Calculate the momentum change of the ball for each case.
Then, explain which ball, if any, experiences the greater force. Show all of
your work."

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

This is one type of line graph in which the independent variable is time plotted on the x axis and the dependent variable, also numerical, is plotted on the y axis.
