Suppose the charge on the inner conducting sphere is +3 µC, while +4 µC of charge is deposited on the conducting shell. (a)Find the surface charge (in µC) on the inner surface of the shell.

(b)Find the surface charge (in µC) on the outer surface of the shell

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
