The electric wire which sag in summer become straght in winter.

Why do the pendulum clock run slow in summer and fast in winter?

The electric field due to an infinitely long straight uniformly charged wire at a distance r is directly proportional to

A wire has a length of 2.0m and a resistance of 5.0(Omega) .Find the electric field existing inside the wire if it carries a current of 10A.

Hibernation is a state of inactivity in which the body temperature drops with a lowered metabolic rate during winter.

The temperature at which the resistance of mercury becomes zero is:

Mud houses are cooler in summer and warmer in winter because

Mud houses are cooler in summer and warmer in winter because

The passage of electric current through a wire, results in the production of

Eiffel tower is made up of iron and its height is roughly 300 m. During winter season (January) in France the temperature is 2^(@) C and in hot summer its average temperature 25^(@) C. Calculate the change in height of Eiffel tower between summer and winter. The linear thermal expansion coefficient for iron alpha = 10xx10^(-6)" per "^(@)C
