Question
Chapter 37, Problem 1CQ
To determine
If the radiated intensity shift towards shorter wavelengths, towards longer wavelengths, or remain the same.
Expert Solution & Answer
Answer to Problem 1CQ
Solution:
Shift towards longer wavelengths.
Explanation of Solution
Given:
The following data is given
A brass plate at room temperature radiates 10 W of blackbody
The plate is cooled to
Formula used:
The wavelength corresponding to the peak of the intensity graph is given by
Where;
T = the temperature of the body in kelvin.
Calculation:
The wavelength corresponding to the peak of the intensity graph is
From the equation, it is clear that the wavelength corresponding to peak of intensity is inversely proportional to the temperature.
Hence, as the temperature increases, the wavelength corresponding to maximum intensity decreases. That is, wavelength shifts towards lower value of wavelengths. But when the temperature decreases the wavelength of the maximum intensity increases. That is the radiated intensity shifts towards longer wavelengths.
Therefore, when the brass plate is cooled to
Conclusion:
The radiated intensity shifts towards the longer wavelengths.

A bobsled starts at the top of a track as human runners sprint from rest and then jump into the sled. Assume they reach 40 km/h from rest after covering a distance of 50 m over flat ice. a. How much work do they do on themselves and the sled which they are pushing given the fact that there are two men of combined mass 185 kg and the sled with a mass of 200 kg? (If you haven't seen bobsledding, watch youtube to understand better what's going on.) b. After this start, the team races down the track and descends vertically by 200 m. At the finish line the sled crosses with a speed of 55 m/s. How much energy was lost to drag and friction along the way down after the men were in the sled?
For what type of force is it not possible to define a potential energy expression?
10. Imagine you have a system in which you have 54 grams of ice. You can melt this
ice and then vaporize it all at 0 C. The melting and vaporization are done reversibly
into a balloon held at a pressure of 0.250 bar. Here are some facts about water you
may wish to know. The density of liquid water at 0 C is 1 g/cm³. The density of ice at 0
C is 0.917 g/cm³. The enthalpy of vaporization of liquid water is 2.496 kJ/gram and the
enthalpy of fusion of solid water is 333.55 J/gram.

- as a hiker in glacier national park, you need to keep the bears from getting at your food supply. You find a campground that is near an outcropping of ice. Part of the outcropping forms a feta=51.5* slopeup that leads to a verticle cliff. You decide that this is an idea place to hang your food supply out of bear reach. You put all of your food into a burlap sack, tie a rope to the sack, and then tie a bag full of rocks to the other end of the rope to act as an anchor. You currently have 18.5 kg of food left for the rest of your trip, so you put 18.5 kg of rocks in the anchor bag to balance it out. what happens when you lower the food bag over the edge and let go of the anchor bag?
