can a liquid exist in vacuum? Wouldn't it vaporize to gaseous form?

Hi JHamm! I know you're not sure; try this: I am sorry but would you believe if I said that the radius of the hemisphere will also decrease when the assembly is plunged into water. If you want more, I shall say that the area of cross-section of the wire of the spring will also increase...

1st: when you understand that, please let me know! Its not easy. 2nd: image may not form on an object always. wall is too rugged to form image of all points of some object on a single plane, so that you could see the image. this will also help you in another way: all things reflect light but...

First, neglect pressure changes over the entire area of your device(this is very realistic). But don't be afraid! Now, the wire your spring is made of shall definitely have a finite cross-sectional area, say "a". The component of the pressure force acting on the curved surface of one hemisphere...

I have a laptop computer, core 2 duo processor. I have another intel processor with me. How if I want to run these two processors in parallel? Is it possible? How so? Thanks!

1. "replace ...with circular skate blades...it would still be stable" Are you sure? I don't think so. What do you think? 2. "...This results in self correction that returns the bike to an upright position" Do you mean that the "self-correction returns the bike to an upright position"...

don't study engineering/science if you want to sell soaps. as simple as that!

Does 'Science precedes technology' or 'technology precedes science?' Think about atomic clocks used in GPS satellites.

A bike "B1" is on the go. Another one, "B2" is standing upright and still. Which one is more stable, in the sense that, if I push one, which one shall fall down more easily?

1. Tension does not hold water within the surfaces. 2. "not letting energy...". Excuse me; are you a physics student? 3. "ignore water tension...not really that important..". I am sorry, it is really important; you don't realize. 4. "I probably...". Why did you have to even write these? You...

Jadaav: try to develop confidence; physics is not something to memorize.

you said: 'a vehicle passed by with a huge sound' The 'huge' sound from the vehicle did nothing to your friend's sound. It cannot! the amplitude induced at your eardrum by the vehicle's 'huge' sound was high; much more than your friend's sound. So even though both the sounds reached your...

simple: if u fancy machine making and using, go for mech. if you love mother Earth more, want to stay close to nature etc., go for civil. Both are great.

Any material reflects light. As simple as that! Try your rough cellphone cover, viewing at a really small angle with the surface. Doesn't it reflect the wall behind?

let the value to be calculated is equal to 'g' so weight of that body is precisely the force due to Earth's attraction: or, mg=GMm/(r*r) here, m is mass of the object and M = mass of that part of Earth enclosed by a sphere having radius same as distance of Earth's center from mariana trench(= r)...
