Answer:
The change in current at is
Explanation:
From the question we are told that
The resistance is
The current is
The change in voltage with respect to time is
The change in resistance with time is
According to ohm's law
differentiating with respect to time using chain rule
substituting value at R = 456
As we know the time period of pendulum is given by the equation
so here
L = length of the pendulum
Now on increasing the temperature due to thermal expansion the length of the pendulum will increase and due to this the time period of the pendulum will also increase
Now due to increase in time period of the pendulum the clock will become slow and it will give incorrect time due to this increase in temperature
