Adensity bottle of glass contains 44.25 at 50°c. calculate the real expansivity of the liquid. take alpha of the glass to be 1.0x10 raised to power-5

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.

Which of the following are forms of phase changes a. freezing b. condensation c. heating d. exchanging
