Answer:
Average velocity of water flow through the pipe = 3.98 m/s
Explanation:
Diameter of pipe = 20 mm
Discharge = 75 L/min
We know that
Discharge = Area x Velocity

Discharge = 75 L/min

Substituting

Average velocity of water flow through the pipe = 3.98 m/s
Answer:
The current in the circuit decrease slowly .
Explanation:
Given as :
For the electrical circuit
The voltage V in the circuit is slowly decreasing
The resistance R of the resistor slowly increasing after heating
Now, From Ohm's Law
Voltage is directly proportional to the flow of current through circuit
I.e V ∝ I
Or. V = R × I
where R is the proportionate constant and this is the resistance of the resistor
whose property is to opposes the flow of current in the circuit
So, If R value more then current I reduces in the circuit
∵ Here in the circuit , The resistance is slowly increasing, so, current I is slowly decreasing .
Hence The current in the circuit decrease slowly . answer
R=ut+gt^2/2
r- displacement (height to find)
u - initial speed (zero)
t - time taken
r=0*5.8 + 10*5.8^2 /2 = 168.2 meters
