What is the power produced by a light bulb with a voltage of 120 volts and a current of 0.045 amps? PLEASE HELP I HAVE 5 MINUTES
2 answers:
Answer : The power produced by light bulb is, 5.4 watts
Solution : Given,
Voltage = 120 V
Current = 0.045 A
Formula used :
where,
P = power produced by light bulb
V = voltage
I = current
Now put all the given values in the above formula, we get the power produced by the light bulb.
Therefore, the power produced by light bulb is, 5.4 watts

3) Saturated citric acid can cause corrosion of the metal layers present in the pipes. So, before draining out any acid it is neutralized so that the pipes and other plumbing works do not get damaged leading to leaks in the drainage system.
Answer:
20 g/mol
Explanation:
We can use <em>Graham’s Law of diffusion</em>:
The rate of diffusion (<em>r</em>) of a gas is inversely proportional to the square root of its molar mass (<em>M</em>).
If you have two gases, the ratio of their rates of diffusion is
Squaring both sides, we get
Solve for <em>M</em>₂:
