A 2800-lb passenger car was originally traveling on a straight section when it gets into a section of the road with a horizontal curve of 750 ft. If the vehicle was originally travelling at 65 mph, a) determine the additional horsepower the vehicle must produce in order to maintain the original speed; b) determine the total resistance on the vehicle as it traverses the horizontal curve. The frontal cross section of the vehicle is 18.5 sq ft with a drag coefficient of 0.39.

Why are graphs useful when interpreting data

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.

If the area of a square has increased by a factor of 16, by how much has each side increased?
