A friend of mine said that if you divide this expression by V, you get P + rhogh + 1/2rhov^2, this because rho (specific mass) = m(mass) / V (volume) and then you get Bernoulli equation. So he said maybe D). Just a stupid way for the teacher to test if we recognize Bernoulli equation in a...

What it seems to me is cinetic energy (0,5mv^2), potencial energy (mgh) and something relates to energy in PV as in Pressure * Volume. But I have no idea what this is either.

Well, believe it or not, this weird question has been present in my teacher's exam several years now. And today I'm having this exam and I'm afraid this crappy question comes up. I've asked here, reddit, asked physics friends. I've had some say is A), some say it's D). I am desperate here, and...

This is all the question description has. No mention of units of any kind :/

Hello! So this is my problem here, there's a question I've been studying for an exam in which I really can't understand the answer. Basically it has multiple choices and I'm very undecided. So this is it: Expression: "What does this expression reflect? PV + mgh + 0,5mv^2 = constant " a)...
