Number three please The temperature of a student's skin is 33.0 degree C. At what wavelength does the radiation emitted from the skin reach its peak? The radius of our Sun is 6.96 times 10^8 m, and its total power output is 3.85 times 10^26 W. (a) Assuming the Sun's surface emits as a black body, calculate its surface temperature. (b) Using the result of part (a), find lambda_max for the Sun. Calculate the energy in electron volts of a...
Consider a person with a surface area of 2.00 m and a skin temperature of 33.0°C. The person is in a room at 20.0°C. What is the net rate of heat transfer by radiation? Hint: See Example 12.23. Submit Request Answer
8. IE (a) If you have a fever, will the wavelength of the radiation component of maximum intensity emitted by your body (1) increase, (2) remain the same, or (3) decrease as compared with its value when your temperature is normal? Why? (b) Assume that human skin has a temperature of 32°C. What is the wavelength of the radiation component of maximum intensity emitted by our bodies? In what region of the EM spectrum is this wavelength?
A. The emissivity of the human skin is 97.0 percent. Use 35.0 °C for the skin temperature and approximate the human body by a rectangular block with a height of 1.55 m, a width of 33.0 cm and a length of 30.0 cm. Calculate the power emitted by the human body. B. What is the wavelength of the peak in the spectral distribution for this temperature? C. Fortunately our environment radiates too. The human body absorbs this radiation with an...
As the temperature of a heated solid increases, what happens to the radiation emitted by the solid? T/F Its peak wavelength increases. T/F Its peak frequency decreases. T/F Its intensity decreases. T/F Its peak wavelength decreases. T/F Its intensity increases. T/F Its peak frequency increases.
The blackbody radiation emitted from a furnace peaks at a wavelength of 7.2 10-6 m (0.0000072 m). What is the temperature inside the furnace?
The blackbody radiation emitted from a furnace peaks at a wavelength of 2.4 10-6 m (0.0000024 m). What is the temperature inside the furnace?
According to Wein’s Law, The peak wavelength of radiation emitted is determined by the temperature of the emitter according to the following equation. λmax=2900/Twhere T is the temperature of the emitter in degrees Kelvin (water freezes at 273 degrees K, 0 degrees Celsius and 32 degrees Fahrenheit). NASA’s Cassini space probe has made several fly-bys of Saturn’s moon Titan, the only moon with an atmosphere. Here is your problem. Given that Earth’s average temperature is 15 degrees Celsius and Titan’s...
2. The average person has 1.4 m2 of skin at a skin temperature of roughly 305 K (90°F) Consider the average person to be an ideal radiator standing in a room at a temperature of 293 K (68°F) (a) Calculate the power (energy per uni i) radiated by the average person in the form of blackbody radiation; express your answer in erg s-1. What is the person's "wattage"? (1 W = 107 erg s-1) Compare this to a typical incandescent...
