Hey, can a physics major help me? I have been wondering about the exact difference between theories laws facts and hypothosis.
I know the general layout but I am still a bit confused.

100 points for answering and if it is a good one.

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.

Remote controls rely on to carry signals and transmit information over short distances.

Given: 1 = 2 if ac = 3, bc = 5, and ab = 7, find ad: 2 4 4 11
