A battery-operated car utilizes a 12.0 V system. Find the charge the batteries must be able to move, in megaCoulombs, in order to accelerate a 750 kg car from rest to 45 m/s, make it climb a 2.14E+02 m high hill, and then cause it to travel at a constant 27 m/s by exerting a 5.00E+02 N force for 55 minutes. Use g = 10 m/s2, if needed.

I have posted the question below :) thank you

In open heart surgery a much smaller amount of energy will defibrillate the heart.(a) What voltage is applied to the 8.00 µF capacitor of a heart defibrillator that stores 60.0 J of energy?kV(b) Find the amount of stored charge.mC

(a) In electron-volts, how much work does an ideal battery with a 37.0 V emf do on an electron that passes through the battery from the positive to the negative terminal? (b) If 7.24 x 1018 electrons pass through each second, what is the power of the battery? (a) Number (b) Number i Units Units

What is the energy (in J) stored in the 21.0 µF capacitor of a heart defibrillator charged to 8.20 ✕ 103 V? and b) Find the amount of stored charge (in mC).

In open heart surgery, a much smaller amount of energy will defibrillate the heart. (a) What voltage is applied to the 8 μF capacitor of a heart defibrillator that stores 44 J of energy? V = kV (b) Find the amount of stored charge in mC. mC = Think & Prepare: The heart defibrillator consists of what electrical component?

In open-heart surgery a small amount of energy will defibrillate the heart. (a) What voltage is applied to the 8.87 µF capacitor of a heart defibrillator that stores 45.5 J of energy? (b) Find the amount of stored charge.

(b) Consider a particular phone that has a battery rated at 4,000 mAh. The battery operates at a potential difference of 3.90 V. How much energy, in units of kilowatt-hours, is stored in a fully charged battery? kWh (c) If electricity costs $0.12 (or 12.0 cents) per kilowatt-hour, what is the value of the total amount of energy stored in this battery? Express your answer in cents (or 0.01 of a dollar). ¢ (d) When the phone is idle (that is, turned on but not making calls or texts, using GPS, or running any power-hungry apps), it will operate continuously for 29.2 hours from a fully charged battery, until the battery runs out. How much average current does the phone draw while idle? Express your answer in milliamperes. mA
