Fig. 16.1 shows the heating system of a hot water shower. Cold water at 15 °C flows in at the rate of 0.0036 m3 minute. Hot water flows out at the samerate.
Calculate the mass of water that passes the heating element in one minute.
The density of water is 1000 kg / m3

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
