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 of length L=2.0m and circumference C=0.8m. For the Stefan-Boltzmann constant use σ=5.67×10−8W/m2/K4. Part A If the surface temperature of the skin is taken to be T_body=30∘C, how...
The power needed to operate your body is about 100 watts. Suppose a human body (of typical mass) could run on fusion power and could convert 0.8 % of its mass into energy. For how long could this body then operate on fusion power?
In this problem you will consider the balance of thermal energy radiated and absorbed by a person in a room. The rate of heat transfer from radiation is: ΔQΔt=eσA(T42−T41)=eσAT42−eσAT41. This equation has two terms which represent the rate of absorption from the room (a gain) and the rate of radiation into the room (a loss). In this problem, we will consider these two terms separately. Assume that the area of a human body may be considered to be that of...
How many D-cell batteries would it take to power a human for 1 day? All numbers must be entered as 5000 or 5e3 or 5.0e3 and not with commas as in "5,000" and not as fractions as in "3/4" and not as percentages as in "70%". Estimate the recomended daily food intake (in Food Calories). Estimate the daily energy (in joule) a human needs. Estimate the voltage (in volt) of one D cell battery. Estimate the charge (in amp-hours) of...
Radiation of Energy The rate of heat transfer by emitted radiation is determined by the Stefan-Boltzmann law of radiation: = aeAT4 where o 5.67x10-8 J/s - m2 K is the Stefan-Boltzmann constant, A is the surface area of the object, and T is its absolute temperature in kelvin. The symbol e stands for the emissivity of the object, which is a measure of how well it radiates An ideal jet-black (or black body) radiator has e 1,whereas a perfect reflector has...
Human body temperatures are normally distributed with a mean of 98.20°F and a standard deviation of 0.62°F. Find the temperature such that only 7% of people have a higher body temperature. Round to the nearest hundredth of a degree.
A.) Estimate the number of H2O molecules in a human body of mass 69.3 kg. Assume that, on average, water makes up about 62.0% of the mass of a human body B.)The average body temperature of a healthy person is 37.0°C. Boltzmann's constant is 1.38 × 10−23 J/K. What is the average kinetic energy of the gas molecules in the lungs?
t is speculated that arsenic (yes, arsenic!) may be an ultra-trace element in the human body, meaning we need it to survive. Nutritionists estimate that a 75.0-kg person may have as much as 12 micrograms of As in their body. What is the concentration of As in ppb? Give your answer to two significant figures. Answer in (ppb As)
