Consider the diffraction pattern obtained from the sunlight incident on a pinhole of diameter 0.1mum . If the diameter of the pinhole is slightly increased, it will affect the diffraction pattern such thtat :

An electric heater of power 150W is immersed in 0.75kg of ice at 0^(@)C in a lagged container of negligible heat capacity. The temperature remains constant for 27.5 minutes and then rises to 40.0^(@)C in further 14 minutes . Calculate the specific heat capacity of water.
