Light from an ideal spherical blackbody 19.0 cmcm in diameter is analyzed by using a diffraction grating that has 3650 lines/cmlines/cm . When you shine this light through the grating, you observe that the peak-intensity wavelength forms a first-order bright fringe at ±± 14.2° from the central bright fringe.
Required:
a. What is the temperature of the blackbody?
b. How long will it take this sphere to radiate 16.0 MJ of energy?

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.
