Four samples of steel, lead, alcohol and glass all have the same mass and are all initially at 20 degree C. After 100 calories of heat is added to each sample, the final temperatures are 38.2 degree C the steel, 85.6 degree C for the lead, 23.4 degree C for the alcohol, and 30 degree C for the glass. Show calculation: Which of these four materials has the largest specific heat capacity?
(a) The steel
(b) The lead
(c) The alcohol
(d) The glass

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.
