Eight identical lights are connected in series across a 110-V line. A. What is the voltage across each bulb? B. If the current is 0.50 A, what is the resistance of each bulb, and what is the power dissipated in each?​

1400 kg car has a speed of 27 m/s. if it takes 7 s to stop the car, what is the impulse and the average force acting on the car?

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° 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.)

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.
