Your equation would hold in at least one particular case: When the momentum change in time is zero and there is actually no force field acting on the body, so the potential energy is also zero. In all other cases, it would just be a blunder, I guess.

https://www.sciencedaily.com/releases/2019/04/190403135011.htm Yale University folks have come up with a new technology which they say can make sound as well as heat flow in one direction only. This is done by using a "standard cavity - optomechanical interaction to produce robust nonreciprocal...

Done. They were skeptical at first. Then one person used the profilometer. The bar was kept on a V block over the device table. The table could be controlled by a computer and joystick on two axes. By taking reference of the end face, diameter at any distance was measured by focusing the image...

I'm being told the CMM isn't absolutely necessary, an optical profilometer that is used to measure roughness would do fine. I'm about to find out soon if it does. It is a large quantity but I'm only going to inspect some samples. In the beginning I had mentioned physical measurement, but I'm...

Thanks. I'll have to enquire about the feasibility of these methods. I think using the micrometer would be cumbersome.

Below is a part proposed to be manufactured. The inspection of this part poses a problem, because vernier callipers only measure distances between parallel surfaces. I know there is some photographic method of measuring distances, however I would like to know is there no way of physically...

Initially assume the system is in equilibrium. So nothing's happening. Now you want to experiment by changing the length of the tubes. So you have telescopic water carrying tubes (I don't know whether such a thing is available). I don't see any way you can control the length of the tubes...

I meant that the ability of solar wind induced fields to have the effect of the same magnitude as that of entire rotating core is what is indigestible

I read it from another source, but here is the university link: http://umu.diva-portal.org/smash/record.jsf?pid=diva2%3A1157328&dswid=-9328 Venus also has a problem with magnetosphere, but this was mars

According to recent research news, swedish PhD scholars have said that solar wind induces currents in the ionosphere of mars. This causes an induced magnetoshere which in turn protects the atmosphere from the same wind. This is quite difficult to believe. It is well known that Mars does not...

What is recoil shift? Does it affect doppler shift?

https://curiosity.com/topics/a-mystery-of-einsteins-relativity-has-been-explained-using-classical-physics-curiosity?utm_source=androidapp If anybody understands what the author is trying to say, kindly elaborate. I haven't read the paper

Think of the problem as a hydraulic open circuit pumped by pressure in tank A and all other tanks as accumulators along the line. Even if you assume all accumulators to be of similar construction and all pipes to be frictionless, you need some more details such as the lengths of the pipes and...

The point is this was not supposed to be a science question in the first place. It was designed just to test how closely the candidate observes the setup and whether he manages to evade the trickery. In fact there is a real possibility that any tank except the ones that have been shut out: D, E...

I've been given the solution. F fills first but what happens later is impossible. https://drive.google.com/file/d/0B0O8pXjmFFrReVNCbkVlZU9DQ00/view?usp=drivesdk
