Chemical X has a mass of 5 grams, and chemical Y has a mass of 10 grams. If the two chemicals
are mixed and a chemical reaction occurs, what is
the mass of the final product. Keep the Law of
Conservation of Mass in mind?
15g or 50g
50g

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.

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

c) up is the direction the magnetic force is acting on the charge.
