An engineer is developing an electric water heater to provide a continuous ("on demand") supply of hot water. one trial design is shown in the figure. (figure 1)water is flowing at the rate f, the inlet thermometer registers t1, the voltmeter reads v, and the ammeter reads current i. then the power (i. e., the heat generated per unit time by the heating element) is vi. assume that the heat capacity of water is c and that the heat capacity of the heater apparatus is ch. part a when a steady state is finally reached, what is the temperature reading t2 of the outlet thermometer? express the outlet temperature in terms of t1, f, c, and any other given quantities. view available hint(s) t2 t 2 t_2 = previous answers incorrect; try again; 5 attempts remaining the correct answer does not depend on: ch. part b complete previous part(s) imagine that the input temperature of the water is t1=18∘c, the ammeter reads i=15.0a, the voltmeter reads v=120v, and the flow rate is f=0.500kg/min. the heat capacity of water c=4200j/(kg⋅k). part c what is the power p at which the heater operates? express your answer numerically, in watts. view available hint(s) p p p = nothing w part d complete previous part(s) part e complete previous part(s) provide feedback figure

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
