A large cavity that has a very small hole and is maintained at a temperature T' is a good approximation to an ideal radiator or blackbody. Radiation can pass into or out of the cavity only through the hole. The cavity is a perfect absorber, since any radiation incident on the hole becomes trapped inside the cavity. Such a cavity at 500° has a hole with area 5.00 mm². Part A How long does it take for the cavity to radiate 200 J of energy through the hole? Express your answer in seconds. ΜΕ ΑΣΦ ?

High-intensity focused ultrasound (HIFU) is one treatment for certain types of cancer. During the procedure, a narrow beam of high-intensity ultrasound is focused on the tumor, raising its temperature to nearly 90°C and killing it. A range of frequencies and intensities can be used, but in one treatment a beam of frequency 4.40 MHz produced an intensity of 1425.0 W/cm. The energy was delivered in short pulses for a total time of 3.40 s over an area measuring 1.80 mm by 5.40 mm. The speed of sound in the soft tissue was 1580 m/s, and the density of that tissue was 1509.0 kg/m?.

Electronics and inhabitants of the International Space Station generate a significant amount of thermal energy that the station must get rid of. The only way that the station can exhaust thermal energy is by radiation, which it does using thin, 1.8-m-by-3.6-m panels that have a working temperature of about 6 °C and an emissivity of 0.85. Part A How much power is radiated from each panel? Assume that the panels are in the shade so that the absorbed radiation will be negligible. The temperature of deep space, which the panels face, is close to 0 K. Hint: Don't forget that the panels have two sides!

Consider a model of an electron as a hollow sphere with radius R and the electron charge -e spread uniformly over that surface. d. Use Einstein’s equation relating rest mass to energy to derive a value for R. Unfortunately, your answer will be model-dependent. The traditional “Classical radius of the electron” is derived by setting the electrostatic work to be e2/(4pi e0 R)

Have you ever chewed on a wintergreen mint in front of a mirror in the dark? If you have, you may have noticed some sparks of light coming out of your mouth as you chewed on the candy; and, without knowing it, you have experienced a physical phenomenon called triboluminescence. In this problem you will analyze some of the key elements of triboluminescence in wintergreen candies. Part C Image that the radiation emitted by the nitrogen at a frequency of 8.88×1014 Hz is absorbed by an electron in a molecule of methyl salicylate. As a result, the electron in the wintergreen oil molecule jumps to an excited state. Before returning to its ground state, the electron drops an intermediate energy level, releasing two-thirds of the energy previously absorbed and emitting a photon. What is the wavelength Xw of the photon emitted by the wintergreen oil molecule? Express your answer in nanometers to three significant figures. ► View Available Hint(s) Aw= Submit [-] ΑΣΦ ? nm
