But that's cheap, and hardly worth even 5 points. If we want to talk energy, let's use the actual scientific unit of energy. ________________________________________________
(110,000 joules/second) x (10,800 seconds) = 1.188 x 10⁹ Joules That's
==> 1,188,000,000 joules
==> 1,188,000 kilojoules
==> 1,188 megajoules
==> 1.188 gigajoules
Atsa nawfulotta energy ! It goes back to that "110 kw appliance" that we started with. That's no common ordinary household appliance. 110 kw is something like 147 horsepower. In order to bring 110 kw into your house, you'd need to take 458 Amperes through the 240-volt line from the pole. Most houses are limited to 100 or 200 Amperes, tops. And the TRANSFORMER on the pole, that supplies the whole neighborhood, is probably a 50 kw unit.
That would depend on the man’s starting latitude. If 6.7 mi south of the north pole, for example, the resultant would be 6.7 mi due north of the starting point.
The current is reduced to half of its original value.
Explanation:
Assuming we can apply Ohm's Law to the circuit, as the internal resistance and the load resistor are in series, we can find the current I₁ as follows:
where Rint = r and RL = r
Replacing these values in I₁, we have:
When the battery ages, if the internal resistance triples, the new current can be found using Ohm's Law again:
We can find the relationship between I₂, and I₁, dividing both sides, as follows:
The current when the internal resistance triples, is half of the original value, when the internal resistance was r, equal to the resistance of the load.
