An older camera has a lens with a focal length of 60mm and uses 34-mm-wide film to record its images. using this camera, a photographer takes a picture of the golden gate bridge that completely spans the width of the film. now he wants to take a picture of the bridge using his digital camera with its 14-mm-wide ccd detector. what focal length should this camera's lens have for the image of the bridge to cover the entire detector?

1. study the scenario. the particles in some system are moving around quickly. a few minutes later, the particles are moving, on average, more slowly. how does this change in motion affect the temperature of the system? the temperature of the system did not change. the speed of the particles does not affect temperature, the number of particles affects the temperature.the temperature of the system is lower now than it was initially. faster moving particles result in a higher temperature for the system.the temperature of the system is higher now than it was initially. slower moving particles result in a higher temperature for the system.the temperature of the system did not change. the speed of the particles has no effect on the temperature, only the type of atom affects the temperature.
