Pls help pls pls I ve been working on this for so long

(C) 1 1/2 mph

Step-by-step explanation:

There are 3 1/3rds in a hour. So you would multiply the rate by 3, since there's 3 in an hour.

0.5 * 3 = 1.5 mph or 1 1/2 mph (C)

correct answer:

b.(19,-2)

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
