In a physics lab students are conducting an experiment to learn about the heat capacity of different materials. The first group is instructed to add 1.5-g copper pellets at a temperature of 92°C to 335 g of water at 16°C. A second group is given the same number of 1.5-g pellets as the first group, but these are now aluminum pellets. Assume that no heat is lost to or gained from the surroundings for either group.
(a) If the final equilibrium temperature of the copper pellets and water is 27°C, how many whole pellets did the first group use in the experiment? The specific heat of copper is 0.0924 kcal/(kg · °C). Answer in Pellets
(b) What is the equilibrium temperature of the aluminum and water mixture for the second group? In Degrees Celcius
Three positive particles of equal charge +17uC are placed at the corners of an equilateral triangle of side 15.0 centimeter. Obtain the magnitude and direction of the net force on each particle due to the other two
Consider a frictionless track. A block of mass m1=10.0kg is released from A, at a height h=17.0m. It makes a head-on elastic collision at B with a block of mass m2=22.0kg that is initially at rest. Calculate the maximum height to which m1 rises after..
