Three identical point charges ( q = + 2,7. 10-6C) are placed on the corners of an equilateral triangle whose side have a length of a = 35 cm. What is the magnitude of the resultant electric field: a) At the center of the triangle? b) At the corner of the triangle?

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

cant without the picture! ?

part 1: which substance has a higher solubility?

a

smallest amount left undissolved atall temps in table shown most has dissolved high sol'by
