Consider a coil of radius, rcoil, placed on a magnet which has strength, [10] bcenter, at the center of the coil, and bouter at the coil radius.

write the equation for a line, b(r), which takes the value, bcenter, at r = 0 and the value, bouter, at r = rcoil.

What are similarities and differences of reflection, refraction, diffraction and absorption?

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s.t.p.?

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
