While taking a shower, you notice that the shower head is made up of 36 small round openings, each with a radius of 1.4 mm. you also determine that it takes 7.0 s for the shower to completely fill a 1- liter container you hold in the water stream. the water in your house is pumped by a pump in the basement, 6.2 m below the level of the shower head. the pump maintains an absolute pressure of 1.6 atmospheres. neglect viscosity. use g = 9.8 m/s/s, and 1 atmosphere = 101,300 pa.

[1 point] (a) what is the total area of the openings in the shower head?

[2 points] (b) at what speed is the water emerging from the holes?

cconnected to the pump (assume it has a constant cross-sectional area)?

[2 points] (c) at what speed is the water flowing through the pipe

[2 points] (d) what is the radius of the pipe?

[1 point] (e) if you covered up six of the holes in the shower head with your thumb, with what speed would you expect the water to emerge from the remaining holes?

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
