Q1 a rectangular block of ice 13 m on each side and 14 m, Ask an Expert

Academics

Q1. A rectangular block of ice 13 m on each side and 1.4 m thick floats in sea water. The density of the sea water is 1025 kg/m3. The density of ice is 917 kg/m3.

a) How high does the top of the ice block float above water level?

b) How various penguins of mass 16 kg each can stand on the ice block before they find their feet wet?

Q2. Light passes through a 230 lines/mm grating and is observed on a 1.0m wide screen located 1.1m behind the grating. Three bright fringes are seen on both sides of the central maximum.

Determine Maximum wavelength and Minimum wavelength?
