In a particular solid-liquid phase transition the point po, to lies on the coexistence curve. the latent heat of vaporization at this point is lo. a nearby point on the coexistence curve has pressure po+ p and temperature to+ ; the local slope of the coexistence curve in the p-t plane is p/t. assuming v, cp, a, and k to be known in each phase in the vicinity of the states of interest, find the latent heat at the point po + p, to + t.

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
