When the hamster is running in a wheel, the temperature of the air in the calorimeter rises 1.60 per hour. How much heat does the running hamster generate in an hour? Assume that all this heat goes into the air in the calorimeter. You can ignore the heat that goes into the walls of the box and into the thermometer, and assume that no heat is lost to the surroundings.When the hamster is running in a wheel, the temperature of the air in the calorimeter rises 1.60 per hour.

An ethernet cable is 3.95 m long and has a mass of 0.190 kg. A transverse pulse is produced by plucking one end of the taut cable. evaluate the tension in the cable
The equations of state for electromagnetic radiation in thermodynamic equilibrium with a cavity of volume V at temperature T are P=a T^4/3 and U=a T^4 V, Find the heat capacity for an isochoric (i.e., constant volume) process
What would be the final temperature of 100g of 16°C water when 107 g of 40°C iron nails are submerged in it? (The specific heat of iron is 0.12 cal/g °C. Here you must equate the heat gained by the water to the heat lost by the nails.)
A point charge is moved in an electric field. The potential changes from -87 V to +30 V between the initial and final position. The work done by the electric field is 156 J
