Integrated Concepts (a) Calculate the rate in watts at which heat transfer through radiation occurs (almost entirely in the infrared] from 1.0 m2of the Earth’s surface at night. Assume the emissivity is 0.90, the temperature of the Earth is 15°C, and that of outer space is 2.7 K. (b) Compare the intensity at this radiation with that coming to the Earth from the Sun during the day, which averages about 800 W/m2, only hall of which is absorbed. (c) What is the maximum magnetic field strength in the outgoing radiation, assuming it is a continuous wave?
Integrated Concepts If you want to cook in water at 150C, you need a pressure cooker that can withstand the necessary pressure.

Show that the moment of inertia of a diatomic molecule is I=r02 , where is the reduced mass, and r0 is the distance between the masses.
A quality assurance engineer at a frying pan company is asked to qualify a new line of nonstick-coated frying pans. The coating needs to be 1.00 mm thick. One method to test the thickness is for the engineer to pick a percentage of the pans manufactured, strip off the coating, and measure the thickness using a micrometer. This method is a destructive testing method. Instead, the engineer decides that every frying pan will be tested using a nondestructive method. An ultrasonic transducer is used that produces sound waves with a frequency of f=25 kHz. The sound waves are sent through the coating and are reflected by the interface between the coating and the metal pan, and the time is recorded. The wavelength of the ultrasonic waves in the coating is 0.076 m. What should be the time recorded if the coating is the correct thickness (1.00 mm)?
