Can someone with this question i need it done will give you all my points and brainliest.

Step-by-step explanation:

Here, the two triangles are congruent.

we know, for congruent triangles-

corresponding sides are congruent.

From the figures, we get

triangle PQR is congruent to triangle LKJ

Here,

corresponding sides are-

PQ and LK ; QR and KJ ; PR and LJ

Hence, we get

PQ ≅ LK ; QR ≅ KJ ; PR ≅ LJ

i found two solutions,   n = 2 • ± √3 = ± 3.4641

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
