Answer:
The height is increasing at the rate of 0.42 ft/min
Step-by-step explanation:
Given that:
The diameter = height
and
diameter d = 2 r
2 r = h
r =
The volume of the cone formed = v
v ⇒ = 40 ft³/ min
at h = 11 ft high
Hence, the height of the pile was increasing at the rate of 0.42 ft/min
<u>Answer</u>-
<em>The total capacitive reactance of the circuit is </em>442.10<em> Ω.</em>
<u>Solution-</u>
Three capacitors, a 12 mF, a 20 mF, and a 30 mF, are connected in series to a 60 Hz source.
The effective/equivalent capacitance of the circuit is,
When capacitors are joined in series, the total value of capacitance in the circuit is equal to the reciprocal of the sum of the reciprocals of capacitance of all the individual capacitors.
We know that,
Where,
= Capacitive Reactance (in Ω)
f = frequency (in Hz)
C = Capacitance (in F)
Here given,
= ??
f = 60 Hz
C = 6 mF = F
Putting the values in the formula,
Therefore, the total capacitive reactance of the circuit is 442.10 Ω.
