Answer:
the charge generated in the circuit is 240 C.
Explanation:
Given;
current flowing in the circuit, I = 2A
time of current flow, t = 2 minutes = 2 x 60s = 120 s
The current flowing through a given circuit is defined as the quantity of charge flowing through the circuit in a given time.
where;
Q is the charge flowing in the circuit
Q = 2 x 120
Q = 240 C
Therefore, the charge generated in the circuit is 240 C.
Answer:
The speed in the smaller section is
Explanation:
Assuming all the parts of the pipe are at the same height, we can use continuity equation for incompressible fluids:
(1)
With Q the flux of water that is with A the cross section area and v the velocity, so by (1):
subscript 2 is for the smaller section and 1 for the larger section, solving for :
(2)
The cross section areas of the pipe are:
but the problem states that the diameter decreases 86% so , using this on (2):
