A 1400-kg car is traveling on a level road at a constant speed of 66 mi/h. The drag force exerted by the air on the car and the rolling friction force exerted by the road on the car tires add to give a net force of 790 N pointing opposite to the direction of the car's motion. What is the rate of work done by the air and the road on the car?

Write down two additional questions about earth's magnetic field that will make your presentation more informative.

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.

Suppose that two objects attract each other with a gravitational force of 16 units. if the distance between the two objects is double, what is the new force of attraction between the two objects?
