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:
F' = F/16
Explanation:
The gravitational force between masses is given by :

If the distance between the center of two objects is quadrupled, r' = 4r
New force will be :

So, the new force will change by a factor of 16.
