In film photography, shutter speed is the length of time that the film is exposed to the scene you’re photographing. Similarly,
iogann1982 [59]

Answer:

a. 1/1000 sec

Explanation:

Shutter speed is the length of time that the film you’re photographing is being exposed to the scene in film photography. However, in digital photography, shutter speed is the length of time that the image sensor sees the scene the photographer is trying to capture.

For shutter speeds, the greater the denominator the higher the speed and the lower the denominator, the lower the speed.

Thus, the fastest one is option A.

A student lifts a 90 pound (lb) ball 4 feet (ft) in 5 seconds (s). How many joules of work has the student completed?
scZoUnD [109]

Wending your way through this question and the list of choices
is like running through a corn-maze on a moonless night with
your eyes closed.

Work = (force) x (distance)

Keeping with the units used In the question ...

       Work = (90 pounds) x (4 feet)  =  360 foot-pounds .

If you want the work expressed in joules, then you need to convert
pounds and feet to newtons and meters.

           (90 pounds) x (4.448 newtons/pound) =  400.32 Newtons

               (4 feet) x (1 meter / 3.28084 feet)  =  1.219 meters

Work = (force) x (distance)

          = (400.32 newtons) x (1.219 meters) = 488.1 joules .
