Help! I have this assignment for physics. 1. You place a book on a table. Someone asks you to draw the forces acting on the book. What force diagram do you show them?

2. A car has come to a complete stop at a red light. Draw the force diagram for this car at rest.

3. A car is parked uphill on a sloped street. How would you draw the force diagram to
illustrate all of the forces acting on this car to keep it parked on the slope? (Hint: Don’t
forget to think about frictional forces!)

Which statement correctly describes a step-up transformer? a. it increases the amount of electric energy available. b. it increases the voltage of an electric current. c. it changes direct current into alternating current. d. it has more loops of wire in its primary coil.

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
