A 1,500 kg car traveling at 13.4 m/s (30 mph) applies its breaks and comes to rest in 5.5 seconds. If the brake discs begin at room temperature (20.0°C), what is their final temperature after the car comes to a rest? Assume: 1. ALL the work done by friction enters the car's brake discs 2. The work is shared equally between the four discs 3. The discs are made of high -carbon steel (c=0.50 J/g) 4. The four discs have a combined mass of 28 kg Give your answer in °C to three significant figures (one decimal place).

A rubber band at temperature T is fastened at one end to a peg, and supports from its other end a mass m in a gravitational field g. Model the rubber band as a linked polymer chain of N segments joined end-to-end. Each segment has a length a and can be oriented either parallel or anti-parallel to the vertical direction. Find an expression for the average length of the rubber band as a function of B, m, g, N, and a. You may neglect the kinetic energies and masses of the segments themselves, and any interaction between the segments.
The urban heat island effect is often strongest at night when temperatures would typically drop. What does this indicate about energy transfer and the material used in the building? (a) The material in buildings releases more energy at night than it absorbs during the day (b) The material in buildings absorbs a lot of energy during the day and when it gets colder at night the energy is released back into the cooler air. (c) The material in buildings absorbs energy during the day and releases it because the temperature of the buildings is lower than the cooler air (d) The material in buildings releases a lot of energy into the hot air during the day so at night all of the energy is still there

A typical coal-fired power plant burns 300 metric tons of coal every hour to generate 2.7 × 106 MJ of electric energy. 1 metric ton = 1000 kg; 1 metric ton of coal has a volume of 1.5 m3. The heat of combustion of coal is 28 MJ/kg. Assume that all heat is transferred from the fuel to the boiler and that all the work done in spinning the turbine is transformed into electric energy.a. Suppose the coal is piled up in a 10 m × 10 m room. How tall must the pile be to operate the plant for one day?b. What is the power plant’s efficiency?
