Manufacturers of headache remedies routinely claim that their own brands are more potent pain relievers than the competing brands. their way of making the comparison is to compare the number of molecules in the standard dosage. tylenol uses 325 mg of acetaminophen (c8h9no2) as the standard dose, while advil uses 2.00 x 102 mg of ibuprofen (c13h18o2). find the number of molecules of pain reliever in the standard doses of

(a) tylenol and
(b) advil.

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
