Well, we usually assume that the resistance of a circuit component
is constant and doesn't change. But the truth is that for anything
that conducts current, its resistance always increases somewhat
when it warms up.
For things like light bulbs, electric toasters, space heaters, electric
stove burners, the heat coils in a blow-dryer ... anything that's
designed to be really hot when it's doing its job ... the resistance
of those things increases significantly when they come up to their
operating temperatures.
Answer:
his movement is proportional to the intensity of the earthquake,
Explanation:
An earthquake is a record of the intensity of an earthquake as a function of time.
Where the intensity is plotted on the y-axis, which corresponds to the vertical movement of the detector, this movement is proportional to the intensity of the earthquake, therefore the intensity increases the amplitude of the oscillation increases.
And the in x corresponds to time
Answer:
The potential energy change is 0.596 J.
Explanation:
Given that,
Potential difference =14.9 V
Charge q =0.0400 C
We need to calculate the change potential energy
The potential energy change is the product of the charge and potential difference.
Using formula of change potential energy
Hence, The potential energy change is 0.596 J.
