Physics, Paper I

State and prove Stoke's theorem.

( 1.4 − 1 ) × 150 π J ​ = 0.5 0.4 × 150 π ​ Pa = 120 π Pa ≈ 377 Pa . The final pressure ( $P_f$ ) is: $P_f = P_0 + \Delta P = 101325 \text{ Pa} + 377 \text{ Pa} = 101702 \text{ Pa}$ . Final Pressure: 101702 $101702 \text{ Pa}$ 4a What is viscosity? Discuss effect of temperature on the viscosity of liquids and gases.

Discuss analytical treatment of interference of light to calculate intensity in double slit interference. Describe the conditions of maximum and minimum intensity and also draw the intensity pattern for double slit interference.
