The dubois formula relates a person's surface area, s, in meters2, to weight, w, in kg, and height, h, in cm, by (a) what is the surface area of a person who weighs 60 kg and is 160 cm tall? (b) the person in part a stays constant height but increases in weight by 0.4 kg/year. at what rate is his surface area increasing when his weight is 64 kg?

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply. the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
