Stream Definition and 159 Threads

A few months later, I will have a choice between "theoretical physics stream" and "applied physics stream". but i don't know which one is more suitable for me. In high school, I would definitely choose theoretical stream coz I hated doing experiment so much. But after one semester in...

a stream of water exits from the nozzle of a hose at a speed of 16m/s. the vertical wall of a burning building is a horizontal distance D=4.0 m away from the nozzle. I understand and got the correct answers for the first two questions, but i need help on the third question. 1.) if the nozzle...

Maybe you, chemical people could answer my question. Imagine a fuel injector surrounded by a coaxial air stream. The fuel and air flow are parallel, coaxial and axisymmetric. Both fluids obey ideal gas equation. Let's consider steady and compressible flow, i.e, variations of \rho are...

The stream of water from a faucet decreases in diameter as it falls. Derive an equation for the diameter of the stream as a function of the distance y below the faucet, given that the water has speed v0 when it leaves the faucet, whose diameter is D. The water molecules in contact with the...

I am going to pursue Engineering at graduation level. But I'm confused about which type of engineering is best. I have three options: 1) BioTechnology 2) Instrumentation and control 3) Information Technology All are equally interesting to me. Please help me decide which one has the best...

I know this sounds stupid but I still find it hard to digress QM. Could anyone give me a picture of how a photon is like? And how will a stream of photon (being light) looks like? At least an approximation, if possible.

What is Light? What is Light? Is it a EM wave or a stream of photons? Is there any theory which can explain all the phenomena of light? P.S.: Another question, What makes glass transparent?

Electricity is the movement of electrons from attom to atom but how are streams of electrons shot through the air to hit a phosphor screen in a TV or monitor by an electron gun? I have heard of electrical arc's but when those are preformed there are usually sparks going every where so I know it...
