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.

An object of mass 7.90 kg falls through a height of 40.0 m and, by means of a mechanical linkage, rotates a paddle wheel that stirs 0.620 kg of water. Assume that the initial gravitational potential energy of the object is fully transferred to thermal energy of the water, which is initially at 13.0°C. What is the temperature rise of the water?
20:36 M Q4. A substance takes in energy of Q 1 point to increase its temperature by AT. Which formula can calculate the heat capacity (C) of the substance? * C-Q ΔΤ C = Q/AT C- ΔΤ/Q Q5. The more massive a substance, 1 point the the heat capacity. * smaller same larger Q6. The specific heat capacity of a 1 point substance is defined as: * the amount of energy required for substance of 1 kg to increase the temperature by 1 °C. the amount of energy for a substance required to increase the temperature by 1 °C. the volume of substance to store 1 °C of heat.

A steel rod (p=7860 kg/m³) has a length of 3.75 m. It is bolted at both ends between immobile supports. Initially there is no tension in the rod, because the rod just fits between the supports. Find the tension that develops when the rod loses 3190 J of heat. Number ! Units N
You wish to buy a new freezer for your basement. The primary use of the freezer will be to prepare ice for family parties. You have a very large family, with grandparents, parents, sisters, brothers, uncles, aunts, cousins, nephews, nieces, and grandchildren. As a result, family birthday parties are held every couple of weeks, and you need lots of ice for drinks. You want the freezer to convert 10.5 kg of water at 23.5°C to 10.5 kg of ice at -8.6°C in 2.00 h. But, in order to keep your electric bill down, you want the power rating of the freezer to stay below 100 W. From these requirements, you determine the minimum COP of the freezer that will satisfy your needs. (Consider that the specific heat of water is 4,186 J/(kg. °C), the specific heat of ice is 2,090 J/(kg. °C), the latent heat of fusion of water is 3.33 x 105 J/kg, and the latent heat of vaporization of water is 2.26 x 106 J/kg.)

Is increasing the temperature of the surroundings the only effect of this "lost" kinetic energy? If the ground is soft, a hard steel ball like this might cause the ground to deform. It does work on the ground while moving. But, once everything comes to a stop we find the kinetic energy just before impact has been converted to thermal energy. The temperature of the affected areas increases, though slightly. Eventually, this thermal energy spreads into the atmosphere and surrounding areas, making any temperature changes undetectable. We might instead drop the ball onto a hard surface. The ball itself might deform or break, and some of the kinetic energy might go into the motion of fragment particles that fly in all directions. But again, in the end, all the kinetic energy is dissipated into thermal energy. What about a case where a ball bounces? Say a rubber ball, with a mass of 0.020 kg, is dropped from rest at a height of 1.75 m. It rebounds off the floor, and reaches a maximum height…
