I thought you were going to ask for the resistance of the unknown
series resistor. Since you only want the equivalent resistance of the
circuit, you don't even need to know the resistance of the lamp.
I = E / R
Current through the circuit = (voltage of the battery) / (circuit resistance).
0.5 = (12) / R
Multiply each side by 'R' : (0.5) R = 12
Multiply each side by 2 : <em>R = 24 ohms</em>
(Since the resistance of the lamp is 10 ohms, the
unknown series resistor is the other 14 ohms.)
Answer:
You should be physically active because you need to exercise or you might become overweight/obese. Exercise helps burn off calories which cause obesity. It is also good for your heart and lungs it keeps them active and healthy.
Answer:
Discharge Rate = 0.2 cubic meters per second
Explanation:
Torricelli's Law is derived from Bernoulli's equation and simply states that the speed of the efflux in a Torricelli apparatus (shown below) is directly proportional to and affected only by the height of the fluid above it.
V = √2g(10-2)
Putting value of g = 9.8 we get:
V = 12.52 m/s
Discharge rate = Q = A × V
= 1.60/100 × 12.52
= 0.2 cubic meter per second
