Answer:
= 591.45 T/s
Explanation:
i = induced current in the loop = 0.367 A
R = Resistance of the loop = 117 Ω
E = Induced voltage
Induced voltage is given as
E = i R
E = (0.367) (117)
E = 42.939 volts
= rate of change of magnetic field
A = area of loop = 7.26 x 10⁻² m²
Induced emf is given as
= 591.45 T/s
Answer : The correct option is, (A)
Solution : Given,
Volume of mercury at temperature =
As we know that the mercury is a liquid substance. So, we have to apply the volume of expansion of the liquid.
Formula used for the volume expansion of liquid :
or,
where,
= volume of liquid at temperature
= volume of liquid at temperature
= volume of liquid at temperature
= volume expansion coefficient of mercury at
is 0.00018 per centigrade (Standard value)
Now put all the given values in the above formula, we get the volume of mercury at .
Therefore, the volume of mercury at is,
