Athin rod extends along the z -axis from z = −d to z = d . the rod carries a positive charge q uniformly distributed along its length 2d with charge density 37.99 c/m . if the electron started out at rest at the point z = 4d , what is its velocity at z = 3d ? (take elementary charge 1,6x10-19 c , take coulomb's constant 9x109 nm2c-2 and take mass of electron 9,1x10-31 kg). write your answer in multiples of 1010 m/s. and write your answer in two decimal places.

An insulated thermos contains 148 g of water at 72.7 ˚c. you put in a 11.7 g ice cube at 0.00 ˚c to form a system of ice + original water. the specific heat of liquid water is 4190 j/kg•k; and the heat of fusion of water is 333 kj/kg. what is the net entropy change of the system from then until the system reaches the final (equilibrium) temperature?
