An all-electric car (not a hybrid) is designed to run from a bank of 12.0 V batteries with total energy storage of2.30 x 10' ).7.(a) If the electric motor draws 6.40 kW as the car moves at a steady speed of 20.0 m/s, what is the current (in A)delivered to the motor?(b) How far (in km) can the car travel before it is "out of juice"?km(c) What If? The headlights of the car each have a 55.0 w halogen bulb. If the car is driven with both headlights on,how much less will its range be (in m)?m

Given Data: Power is P=6.4 kW Voltage is V=12 Volt Total Energy is E=2.3×107 J Velocity of the car…

A battery-operated car utilizes a 12.0 V system. Find the charge the batteries must be able to move in order to accelerate the 750 kg car from rest to 25.0 m/s, make it climb a 2.00×102 m high hill, and then cause it to travel at a constant 25.0 m/s by exerting a 5.00×102 N force for an hour.
Hi, I have a question regarding electromagnetism. The question is as follows: An aluminum rod has a resistance of 1.590 Ω at 20.0°C. Calculate the resistance of the rod at 102°C by accounting for the changes in both the resistivity and the dimensions of the rod. The coefficient of linear expansion for aluminum is 24.0 ✕ 10-6 (°C)−1.
Lightbulb A is marked "10.0 W 120 V," and lightbulb B is marked "60.0 W 120 V." These labels mean that each lightbulb has its respective power delivered to it when it is connected to a constant 120-V source. (a) In what time interval does 1.60 J pass into lightbulb A?(b) By what mechanisms does this energy enter and exit the lightbulb? Explain. (c) Find the cost of running lightbulb A continuously for 30.0 days, assuming the electric company sells its product at $0.110 per kWh.

Lightning is a spectacular example of electric current in a natural phenomenon. There is much variability to lightning bolts, but a typical event can transfer 10^9 J of energy across a potential difference of perhaps 5 x 10^7 V during a time interval of about 0.2 s. Use this information to estimate (a) the total amount of charge transferred between cloud and ground (b) the current in the lightning bolt (c) the average power delivered over the 0.2 s.
