Explanation Given info: The height of doughnut is H , the diameter is D , the height of the white stripe is 0.22 H and the density of hot vegetable oil is ρ = 919 kg / m 3 . Explanation: The slope of the graph is, slope ( m ) = vertical component horizontal component = 0.5 − 0 0 − 0.25 = − 2 Write the expression for straight line, y = m x + c (1) For vertical axis y = + 1 , the horizontal axis x has a value of zero. Substitute + 1 for y and 0 for x in equation (1) to find c . + 1 = 2 ( 0 ) + c c = 1 At the point 0.22 for y the corresponding value of x is calculate as, Substitute 0.22 for y , 1 for c and -2 for m in equation (1) to calculate corresponding horizontal value x . 0.22 = ( − 2 ) x + 1 x = 0.39 Write the expression for doughnut density, ρ d = 0. 39 × ρ Here, ρ d is doughnut density

A sealed cubical container contains helium gas at a temperature of 22.5°C. What is the average velocity of one of these helium atoms? A helium atom has a mass of 6.64x10-27 kg kB = 1.38 x 10-23 J/K

P3. After a particularly cold night, Alice leaves a tub of water outside. You may consider the ground and air to have temperatures of T. = -10°C and T = 10°C respectively. How thick is the layer of ice that forms at the bottom of the tub of water, after the tub has been left outside for a long time? The tub of water initially has a layer of water of thickness họ = 10 cm. You may assume that the ground and air remain at a constant temperature throughout, and that the side lengths of the tub a, b > ho, i.e. the heat conduction is one- dimensional. Density of ice and water are Pice = 920 kg/m³ and Pw = 1000 kg/m³. Ice and water have thermal conductivities of kice = 2.22 WK-1m-1 and kiw = 0.556 W K-1m-1.
