What creates an electric force field that moves electrons through a circuit? А. energy source
B. load
C. metal wires
D. resistance

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.

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

In what direction does an applied force move an object
