At new temperature T °C,
change in length of rod is,
∆LS = L0(αS∆T) = 50.00(12 × 10-6 × 100)
= 0.06 cm.
Hence, the actual length of rod at T °C,
LS = 50.06 cm
Due to change in...

When the piece of ice falls from the height h, it possesses potential energy, mgh.
This P.E. is converted to heat energy.
∴ Q = mgh
But only \(\frac{1^{th}}{4}\) of it is absorbed...
When bar magnet is cut into two equal parts, then magnetic moment of each part becomes half of the original directed from S to N pole.
∴ Magnetic moment of the combination...
