Problem 10: Suppose a battery operates a 1.95 W electric clock for 16 months. A) What is the available energy content, in joules, of the battery? B) How many years can a battery that supplies 7.75 X 10' J run a pocket calculator that consumes energy at the rate of 0.95 x 10-3 W? Problem 4: Consider the kinetic energy of a 22000-kg truck moving at 107.5 kmh and that of an 92.5- kg astronaut in orbit moving at 27500...
The total charge a battery can supply is rated in mA·h, the product of the current and the time that the battery can provide this current. A battery rated at 1000 mA·h can supple a current of 1000 mA for 1.0 h, 500 mA for 2.0 h, and so on. (a) A typical AA rechargeable battery has a voltage of 1.2V and a rating of 1800 mA·h. For how long could this battery drive current through a long, thin wire...

When a lightbulb is turned on, 6.70 C of charge pass through the filament of the bulb in 10.0 s. How many electrons pass through the filament in 5 s?
A particular 3 volt battery can send a total charge of 96 amp-hours through a circuit from one terminal to the other. (Because 1 amp = 1 C/s, an amp-hour is a measure of charge.) How many coulombs of charge does this represent? If this entire charge "falls" through a potential difference of 3 volts, how much energy is involved? (That is, enter the *magnitude* only...)

To charge a dead battery do you connect the (+) of the good battery to (+) of the dead battery and (-) of good to () of bad or the (+) of good battery to (-) of dead battery and () of good to (+) of bad battery? 15. Two copper wires of the same length and different diameters are connected in parallel In which case is (a) the resistance and (b) current in the...
A battery is connected in series to an inductor and a resistor. After a long time, assuming the battery does not weaken, how is the current through the inductor changing? Select One of the Following: (a) The current through the inductor is approximately zero. (b) The current through the inductor is approximately constant, but non-zero. (c) The current through the inductor continues to increase at the rate it was increasing when the battery was first connected. (d) The current through...
When a lightbulb is turned on, 8.90 C of charge pass through the filament of the bulb in 15.0 s. How many electrons pass through the filament in 7.5 s? (Enter 3 significant number in exponent notation: example 1.02e21)
A 24-volt battery is connected in parallel to a 4-ohm and a 12-ohm resistor. a. What is ΔV4Ω? b. How much energy is lost by 1 C of charge as it flows through the 12-ohm resistor? c. How many coulombs of charge flow through the battery each second? Hints: 1 volt = 1 J/C; 1 ampere = 1 C/s.
1. A metal sphere with a surface area of half a meter squared is charged from neutral to to 96 mC/m2 at a constant rate 8 mA. How many seconds does this take and how many electrons per second are transferred? Use 16x10-20 C for the charge of the electron. 2. Suppose an alkaline 9 V battery can supply 100 mA (to power a small light bulb, for example) for about 4 hours before too much of the voltage is...
