Aconstant electric field of magnitude e = 148 v/m points in the positive x-direction. how much work (in j) does it take to move the charge q =-13 μc from x1 = -81 m, y1 = -131 m, to x2 = 107 m, y2 = 76 m? ( note: the charge is given in micro-coulomb. the symbol in front of the c should be a greek letter mu.)

Amachinist needs to remove a tight fitting pin of material a from a hole in a block made of material b. the machinist heats both the pin and the block to the same high temperature and removes the pin easily. what statement relates the coefficient of thermal expansion of material a to that of material b? a) the situation is not possible, heating block b will shrink the hole in the material as the material expands with increasing temperatureb) material b has the same coefficient of expansion as does material ac) material b has a negative coefficient of expansion and a has a positive coefficient of expansiond) material a has a greater coefficient of expansion than does material be) material b has a greate
