The car and the truck become completely entangled in the collision. a) What is the magnitude and direction of the velocity of the combined car and truck immediately after the collision? b) How much energy is converted into heat (and sound)?
- A container holds 2.3 mol of gas. The total average kinetic energy of the gas molecules in the container is equal to the kinetic energy of a 8.7x10-3 kg bullet with a speed of 870 m/s. What is the Kelvin temperature of the gas? Number i UnitsP3. 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.Chapter 14, Problem 44 A cubical box with sides of length 0.342 m contains 1.220 moles of neon gas at a temperature of 319 K.
