TWO QUESTIONS 1. In a gear box, if the driving gear has 120 teeth and revolves at
60 rev/min. What is the speed of the driven gear with 80 teeth.

2. How many teeth does gear B have, if gear A has 60teeth and.
rotates 20 times while gear B turns 40 times.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

explanation:

overcharge is the right answer system
