Answer:
Power, P = 30 W
Explanation:
We have,
Voltage drop of a circuit is 60 V
Resistance of the resistor is 120 ohms
Current across the circuit is 0.5 A
It is required to find the power conducted by the resistor. Power conducted by a resistor is given by :
V and I are voltage and current
So, the power conducted by the resistor is 30 watts.
I believe you ask about speed at the end of the hose:
The volume of the bucket is 225 liters which is equal to 225
.
Hose's cross section can be counted with the typical circle's area formula (with diameter instead of radius, that's why you've got a fraction):
are filled within 15 second.
As the bucket is being filled you can say that it's volume is the volume of the water that flowed out of the hose, then:
The speed of the water can be counted with equation:
After extracting h from the volume's equation you get:
When you count the fraction you get the answer:
