Thick lens: matrix method the matrix can be expanded 1 as 0 1 0 1 1 m = r n' r2 t 0 and the lens is surrounded by the same medium, . for a thin lens t is negligible, n n'. 1 0 1 m = r2 n 1 multiplying yields 1 1 m = ry r o ancdeskiops example 1: find the system matrix for the think lens shown below given that ri 45 cm, r2 30 cm, t = 5 cm, n, 1.6, and n = n' 1. yo

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

what is the question because that is not a question.

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.
