You have 6 books on your shelf. you notice that 3 of them have red covers, and 3 of them have blue covers.

if you choose 2 books from your shelf at random, what is the probability that 1 will have a red cover and 1 will have a blue cover?

enter your answer as a fraction in simplest form, using the / symbol, like this: 42/53

f is the midpoint of

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
