This really confused how is it that when Cosα is minimum P is maximum? shouldn't it be the oppose? Problem statement (IGNORE): The piston in an engine is attached to a connecting rod AB, which in turn is connected to a crank arm BC (see figure). The piston slides without friction in a cylinder...

I wonder if anyone could help me identify a short story I read back in the 1960s. It might have been in an old (1950s) copy of Astounding Science Fiction magazine. I think the story involved a sea journey but the main thing I recall is that that radio wave communications was interpreted as...

The answer here is A What i did is getting the area as follows, 2×4×1/2 +3×-6×1/2 +4×-6 = -29 and then use this Δω=ωf-ωi -29=ωf-5 ωf=24 but there is no such choice.

May anyone help me I really don get it. How do you draw a pie chart?

Homework Statement UT has jumped over a wall and unfortunately for her, she forgot to bring her sword. Her friend SS decided to shoot the sword to her with a bow. He can bend a bow and arrow so that it gets a potential energy of 179 Nm. It seemed that Ut landed 9 meters behind the wall; a...

Space is endless, I mean the 'real space' outside our universe. Our Universe is said to be about 13.7 billion years old but it is 150 billion years in Diameter. I don't want to get into all the specifics because it does my head in and truthfully I'm not that smart but if the big bang was to...

Hello, Last night I rented Angels & Demons and observed a number of physical flaws. I noticed that the explosion following the annihilation of the antimatter in the canister was not as intense as what I had expected, which may not be a flaw as I am merely a novice in the realm of physics...

Hey, First off note, I did not see the movie yet (so please don't spoil any of it for me :p ), I am merely talking about the book. In the book Angels & Demons, a 'blob' of anti-matter is stolen and used as a bomb. The blob is very small (but still visible to the naked eye) and in the book it...

I'm on page 100 (of 700) and I think I'm done with this book. (skip to the end* if you're only interested in the physics tie-in) The alarm bells started going off in my head when they zeroed in on the plot device in the form of a new component developed at CERN labs that, if in the wrong...

A probably very simple question, but at the moment I cannot find the sollution to it. :confused: take for example the tower of Pisa or any other tower about to fall over. The tower fell to the left and the platform on top now dips 10degrees. Someone measured the vertical height on the right...

Okay, let me solidify something. I have thought on this until I am dizzy. Is it true that you just can't fake the density of a pure element? That if, for example, you have a 10 gram piece of what is supposed to be gold, pure gold, in a cube shape, could you not secretly adulterate it? Could...
