Answer:
(d) 2 pF
Explanation: the charge on capacitor is given by the expression
Q=CV
where Q=charge
C=capacitance
V=voltage across the plate of the capacitor
here we have given Q=500 pF, V=250 volt
using this formula C=
=500×
×
=2×
=2 pF
The statement that correctly describes the circuit is the circuit provided is an example of a CMOS circuit.
<h3>What is a CMOS circuit?</h3>

Answer:
a table
Explanation:
because you can saw the table
Answer:
I would say a level
Explanation:
A level is used as a horizontal reference line, which will tell if the building is leaning to one side, or if its up right. I may be wrong but this is the closest thing I can think of for this question.
Answer:
rate of heat transfer = 9085708.80 W
Explanation:
Given:
Inside diameter, D = 5.1 cm
= 5.1 x
m
Average velocity, V = 7 m/s
Mean temperature, T = (66+38) /2
= 52°C
Therefore kinematic viscosity at 52°C is ν = 0.104 X
/ s
Prandtl no., Pr = 0.021
We know Renold No. is
Re = 
Re = 
= 3.432 X 
Therefore the flow is turbulent.
Since the flow is turbulent and the ratio of L/D is greater than 60 we can use Dittua-Boelter equation.
Nu = 0.023
.
= 0.023 x
x 
= 1221.52
Since Nu = 
h = 
= 
= 225143.3
Therefore rate of heat transfer, q = h.A(T-
q= 225143.3 x 2πrh ( 66-38)
= 225143.3 X 2π X 
= 9085708.80 W
