Answer:
Explanation:
AB = 110 miles
Let the distance of the western station from fire is d.
As according to the diagram, use Sine law
d = 110 x 0.2588 / 0.73
d = 39 miles

Answer:
An increase in air temperature because of its compression.
Explanation:
The Gay-Lussac's Law states that a gas pressure is directly proportional to its temperature in an enclosed system to constant volume.
<em>where P: is the gas pressure, T: is the gas temperature and k: is a constant.</em>
Therefore, due to Gay-Lussac's Law, when the plunger is pushed down very rapidly, the pressure of the air increase, which leads to its temperature increase. That is why cotton flashes and burns.

To get the total resistance in a parallel circuit, you need to remember that unlike in a series, you do not just merely add the resistances. You need to get the reciprocal first of each resistance and add them together.
After adding them, you will get the reciprocal again and then compute for the value. The problem says that there are 4 resistors in the circuit that have a resistance of 75.
Add up the numerator and copy the denominator:
Then get the reciprocal to get the total resistance:
The answer to your question then is A. 18.8.
