To solve this problem we will apply the ideal gas equations for which the product of pressure and volume is defined, as the equivalent between the ideal gas constant by the amount of matter and the temperature, mathematically this equation is described as
Here,
P = Pressure
V = Volume
R = Ideal gas Constant
T = Temperature
n = Number of molecules
The pressure is in atmospheres, and considering the units of the other values we have finally that,
Replacing,
Multiplying the number of moles by Avogadro's number we have,
Therefore the number of ozone molecules in the Earth's ozone layer are
Explanation:
<em><u>GIVEN </u></em><em><u>:</u></em>
Work done(W) = 40 J
Time(t) = 4 s
Power (P) = ?
<em><u>We </u></em><em><u>know </u></em><em><u>that:</u></em>
W = P×t
Therefore,
P= W/t
=40/4
= 10 W
<em><u>Hope </u></em><em><u>it </u></em><em><u>helps</u></em>
This is kind of an awkward situation.
A, B, and C are definitely false:
A ... gasoline is not a renewable resource
B ... hydroelectric dams don't use wind for anything; windmills do
C ... fossil fuels are not renewable resources
So that leaves D, but D is partly absurd too.
Natural gas burning does not produce gases to turn the turbines. Natural gas is burned to produce HEAT, just like on the stove in my kitchen. The heat is used to boil water, and the steam from the boiling water is what turns the turbines to generate electrical energy.
But I guess you gotta pick <em>choice-D</em> as the answer.
Answer:
presence of moisture in air
