Here's the animation from the wiki page: The effect is vastly downgraded, as the rope's expansion is on the same order of magnitude as...

No considering any possible effect of air, the volume of pumped liquid should decrease as the level in the container decreases.

Since there is no energy loss to the environment in this case, the initial thermal energy of each mass of liquid becomes the final...

Correction: Then we are adding 0,35 kg of water at 20 °C into the cup. Could you show us how did you arrive to that amount?

This is a common misconception. When you draw a force in an FBD, the direction shown only says which direction you are taking as...

Not if you look at your system as a whole, which is actually remaining in static balance while supporting exterior forces. Please, take...

Well, I always leave the door open ajar. Finally, once a month, set the washer on hot without anything in the tub, and place bleach or...

All external forces should be considered at the points where they act on the body. D is acting on point Q in the figure you show. But...

To complete the formal solution in post #10. Suppose this problem had a part (b) asking you to find force ##\mathbf D## exerted by the...

Perhaps a formal solution will clarify things for you. Consider the free body diagram on the right. The system consists of the...
