Answer:
<em> 3980.89 ohms</em>
Explanation:
The capacitive reactance is expressed as;
f is the frequency
C is the capacitance of the capacitor
Given
f = 60H
C = C1+C2 (parallel connection)
C = 15μF + 25μF
C = 40μF
C =
Substitute into the formula:
<em>Hence the total capacitive reactance is 3980.89 ohms</em>
Answer:
1963.93 Moles
Explanation:
-We know the standard conversion ratio for the volume of a mole is
Given volume of rooms as
Convert the volume into liters:
#From our conversion ratio above, we get the volume of air molecules in moles as:
Hence, the volume of air molecules is 1963.93 Moles
