Well we know the hypotenuse of the triangle which is 253 m. And we know the angle of the triangle which is 55.8 degrees. So we want to find y. And to find y we use sin. And sin is a ratio, the ratio of the opposite leg, and hypotenuse. So sin(55.8) = y/253. Now we solve for y by multiplying both sides by 253. And finally we get 209.25 as the length of the y component.

An aerosol can of air freshener is sprayed into a room. what happens to the pressure of the gas if it's temperature stays consta

andrezito [222]

We can use the equation of state for an ideal gas to answer the question:
$pV=nRT$
or, by rewriting it,
$p= \frac{nRT}{V}$
where p is the gas pressure, V its volume, T its temperature, n the number of moles of the gas and R the gas constant.

When the gas is sprayed from the can into the room, its volume V has increased, while n (the number of moles of the gas) stayed the same. Since R is a constant and the temperature T also stayed constant, if we look at the formula we see that the numerator didn't change, while the denominator (V) has increased, so the pressure of the gas has decreased.
