A fluid at 1 MPa has a specific volume of 0.2 m3/kg and an entering velocity of 200 m/s. The heat loss is 10 kJ/kg, and the fluid does 180 kJ/kg of work. The fluid leaves the device with a pressure of 200 kPa, a specific volume of 1 m3/kg, and a velocity of 600 m/s. What is the change in the specific internal energy of the fluid?

i think the answer is a, hope this is right, that would be my best guess.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

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.
