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?

When the magnetic domains in a material can be aligned, but eventually drift out of alignment, the material is

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
