Consider that the specific heat of any human body is 3470 J/kg K, how much energy does the body need to burn to reach the fever temperature? The answer (in fundamental SI unit) is ___________ (type the numeric value only, dont use scientific notation)Thermal emission from forehead. Noncontact thermom- eters are used to quickly measure the temperature of a person, to monitor for fever from an infection. They measure the power of the radiation from a surface, usually the forehead, in the infrared range, which is just outside the visible light range. Skin has an emissivity & = 0.97. What is the total power (infrared and vis- ible) of the radiation per unit area when the temperature is (a) 97.0°F (a common early morning temper- ature), (b) 99.0°F (a common late afternoon temperature), and (c) 103°F (a temperature indicating infection)? ww 36.8
- The power radiated by the Sun is 3.83 × 1026 W (The Watt is the SI unit of power, 1 W = 1 J s-1). Given that the power radiated by the Sun is the rate at which energy is radiated by the Sun per unit time, write down a formula relating the total energy radiated by the Sun, E, during a time interval T, and the radiated power, P. Use your formula and the information given above to calculate the total energy radiated by the Sun in exactly 4 hours. Give your answer to 3 significant figures and write it using scientific notation.Weight of the ozone layer 1.0p 1 Incredibly, the ozone layer in the upper atmosphere that protects us from the ultraviolet rays of the Sun varies somewhat but, on the average, would be less than one centimeter thick if it were brought down to sea level. Given that the density of ozone at sea level would be about 2.0 grams per litre, what is the total amount of ozone (in Tonnes) in the upper atmosphere when its sea-level thickness is 0.22 cm? Take the radius of the Earth to be 6400 km. (The volume of a thin skin around an object is the surface area of the object times the skin thickness.) Give your answer in gigatonnes, and do not specify units in the answer box. Answer Show feedback Updated just now 4During a bout with the flu an 80-kg person ran a fever of 39 oC. Consider that the specific heat of any human body is 3470 J/kg K, how much energy does the body need to burn to reach the fever temperature?

- The total rate at which power is used by humans worldwideis approximately 15 TW (terawatts). The solar flux averagedover the sunlit half of Earth is 680 W>m2 (assumingno clouds). The area of Earth’s disc as seen from the Sun is1.28 * 1014 m2. The surface area of Earth is approximately197,000,000 square miles. How much of Earth’s surfacewould we need to cover with solar energy collectors to powerthe planet for use by all humans? Assume that the solar energycollectors can convert only 10% of the available sunlightinto useful power.Example (1-2): Calculate the conductivity of Germanium (Ge) when one donor atom is added to 10 million pure Germanium atoms.
