A wire with a current of 20mA is in a magnetic field with strength 0.6T. If the current points in the negative y direction (downward) and the magnetic field points in the positive x direction (right), what is the size and direction of the force the wire experiences.

The magnetic field of a wire with current I and at a distance d away is measured to be B_0.  If I double the current (so the current is now 2I) and move to be three times as far away (so the distance is now 3d), what is the new magnetic field in terms of B_0. ?

Formic acid is the simplest carboxylic acid, HCOOH. It is the cause of pain in bee and ant stings and nearly a million tonnes are made each year because it is a good preservative. In water, formic acid behaves as a weak acid:

HCOOH_(aq) + H₂O_(l)  ⇌  HCOO^-_(aq) + H₃O⁺_(aq)

The concentration of formate ions (HCOO^-) is increased by adding sodium formate (HCOONa). Which of the statements below is the best explanation of the process of returning to equilibrium after the sodium formate has been added?
