Peter should join Lab thinkers to receive a better deal.

Science buddies costs 190$ for six months.

Lab thinkers costs 170$ for six months.

Step-by-step explanation:

The equations are...

Science buddies: 10+30x -> 10+30(6)=190

Lab thinkers: 45+25x -> 45+25(6)=170

Peter saves 20$ if he chooses lab thinkers.

Sorry for my mistake, this is my new edit.

answer: ur v dumb

step-by-step explanation:

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
