- In this problem you will consider the balance of thermal energy radiated and absorbed by a person. Assume that the person is wearing only a skimpy bathing suit of negligible area. As a rough approximation, the area of a human body may be considered to be that of the sides of a cylinder length L = 2.0 m and circumference C = 0.8 m. For the Stefan-Boltzmann constant use o = 5.67 x 10-8 W/m2 /K4.do question 3pls ty .A 58-kg cross-country skier glides over snow as in the figure below. The coefficient of friction between skis and snow is 0.24. Assume all the snow beneath her skis is at 0°C and that all the internal energy generated by friction is added to snow, which sticks to her skis until it melts. How far would she have to ski to melt 1.5 kg of snow? Your incorrect answer may have resulted from roundoff error. Make sure you keep extra significant figures in intermediate steps of your calculation. m Need Help? Read It Master it

How far would she have to ski to melt 1.5 kg of snow?Please don't copy and written by hand As shown in the figure below, you have a system including a Cadmium vessel with mass Mvessel = 0.477 kg. The vessel contains water with mass Mwater = 0.219 kg. Both the vessel and water are initially at a temperature of 45.0 degrees Celsius. You add steam into the system. The steam has an initial temperature of 157.9 degrees Celsius and a mass of Msteam = 6.9289 kg. The system will reach equilibrium with all the water having vaporized at some final temperature above 100 degrees Celsius.Find the system final temperature, Tfinal = degrees Celsius Material c (J/(kg K)) Aluminum 897 Beryllium 1820 Cadmium 231 Iron 412 Lead 129 Polyethylene 2303 Steel 466 Uranium 116 Water c (J/(kg K)) ice 2090 water 4186 steam 2010
