Straightforward but needs energy concepts) an electron is traveling with initial ki- netic energy k in a uniform electric field. the electron comes to rest momentarily after traveling a distance d. find an expression for the magnitude of the electric field in terms of q, d and k. what is the direction of the electric field? 3. (intermediate. fairly involved) two parallel, metal plates with separation distance de 1.00 cm carry charges of equal magnitude but opposite sign. the plates are oriented hori. zontally. assume the electric field between the plates is uniform, and it has a magnitude of 2,140 n/c. a charged particle with mass 2.00 x 10-16 kg and charge 1.07 x 10- cis projected from the center of the bottom negative plate with an initial speed of 1.04 x 10 m/s at an angle of 37.0° above the horizontal. assume the plates are square with side length=20.0 cm. make a sketch of the problem and answer the following. a) describe the trajectory of the particle. b) which plate does it strike? c) where does it strike, relative to its starting point? i. e., the horizontal distance from the initial position.

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa.
