1. if a spring stretches 35 inches when 65 pounds is attached, then how far will it stretch when 42
pounds is attached?

Set up a ratio with x being the unknown distance:

35/65 = X/42

Cross multiply:

65x = (35*42)

Simplify:

65x = 1470

Divide both sides by 65:

X = 1470 / 65

X = 22.615

It will stretch 22.615 inches ( Round the answer as needed.)

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

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
