Suppose 1,000 joules of input work were applied to a machine with only 8 percent efficiency. What would be its output work?

The focal length of a relaxed human eye is approximately 1.7 cm. when we focus our eyes on a close up object, we can change the refractive power of the eye by about 16 diopters. (a) does the refractive power of our eyes increase or decrease by 16 diopters when we focus closely? explain. (b) calculate the focal length of the eye when we focus closely.

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c
