Question
Chapter 14, Problem 18Q
To determine
Why the heat sinks have a shape like a series of fins glued on top of microprocessor chips.
Expert Solution & Answer
Explanation of Solution
Introduction:
The rate of cooling depends on the surface area.
Heat sinks shaped like series of fins actually have a large surface area. This results in rapid transfer of thermal energy to the surroundings causing cooling. The air flows between the fins and hence, the dissipation of heat increases.

- generated worksheetarrow_forwardWhile cruising down University Boulevard you are stopped by a cop who states that you ran a red traffic light. Because you don't want to pay the stiff fine, you are attempting a physics defense. You claim that due to the relativistic Doppler effect, the red color of the light λ=616 nm appeared green '=531 nm to you. The cop makes a quick calculation of his own and rejects your defense. How fast, in terms of your speed u divided by the speed of light in vacuum c, would you have to drive to justify your claim? Note that the speed u is taken to be a positive quantity.
