As noted in the chapter, the cosmic microwave background radiation fits the Planck equations for a blackbody at 2.7 K.
(a) What is the wavelength at the maximum of the spectrum of the background radiation?(b) What is the frequency of the radiation at the maximum?(c) What is the total power incident on Earth from the background radiation?
Two long straight parallel wires are 12cm apart. Determine the force on wire A due to wire B, and the force on wire B due to wire A.
A uniform rod of mass 3.05×10?2kg and length 0.410mrotates in a horizontal plane about a fixed axis through its center and perpendicular to the rod. What is the angular speed of the rod after the rings leave it
The nonconservative wind and lift forces take the balloon up, doing +9.70 104 J of work on the balloon in the process. Illustrate at what height above the surface of the earth does the balloon have a speed of 7.20 m/s?
You do a physics lab experiment on another planet. A small block is released from rest at the top of a long frictionless ramp that is inclined at an angle of 36.9° above the horizontal, What is the value of g
Dry ice is frozen carbon dioxide. Suppose you have a piece of dry ice with a mass of 200 grams (a little less than half a pound) which you place into a large deflated bag, which you seal. What volume will the bag have expanded to
