Use the hand rule I explained in my first post. Fingers in the direction of the magnetic field and choose the direction of the charge (current in this case) as the opposite direction to the current in the wire creating the magnetic field (so downwards in this case) and point downwards with your...

Take a look at this picture. The direction of the field at the location of the second wire has a single, definite direction.

Ahh for that question you need to find the magnetic field created by each wire. A wire with a current creates a magnetic field that wraps in circles around the wire. To find the direction of the magnetic field stick out your thumb and make a fist. Your thumb points in the direction of current...

Do you know the direction of current? Also can you give an example?

During high school I learned an easier way to use the hand rules. First let your fingers represent the magnetic field and have your fingers point in the direction of the magnetic field (north to south). Then let your thumb point in the direction the charged particle is travelling. Your palm will...

So is there no way to find how the pressure will change with temperature? Also why would the vapour pressure come into play if there is no space in the tank for it to evaporate? I've thought of a way to illustrate my point further with osmosis. Consider a closed cylindrical container half...

Say there was a container filled with liquid floating in space. What would the pressure of the liquid be? Also would it be affected by the temperature of the liquid? I would assume so since faster moving particles would hit the walls of the container with more force. The reason I'm asking is...

In that situation I would agree that the backwards reaction would depend on the surface area of the solid. However, the solid crystal is essentially placed on both sides of the reaction equation in that situation because in order for the deposition to occur the ion has to come in contact with...

But in the hypothetical reaction I posted there is no solid in the backwards reaction.

We started to learn about chemical equilibrium and equilibrium constants a few weeks ago and something has been bugging me. I don't understand why solids and liquids are not included in the equilibrium constants for some reactions. Here's a hypothetical situation with the following reaction...

So for 2 point sources (or 2 slits) the formula for finding the lines of maxima and minima for waves is n(lambda)=dsin(theta) and when n is an integer you would expect to find a maxima. However, I don't understand why this formula also applies to diffraction gratings since there are way more...

I think your teacher is confusing work with impulse.

Hmm interesting but I don't understand why the waves going out at wider angles on a wider slit is canceled out more than on a thinner slit. If you have a diagram or something to illustrate this then that would be very helpful. Also another question. Is the concept of the rectilinear propagation...

This isn't exactly a homework question but just a few conceptual questions I'm confused about. First off on the topic of diffraction I notice many textbooks and other resources say that diffraction is more evident when the width of a slit is close to the wavelength of the wave. However, they...

Ahh some of my confusion may have arose because I didn't understand how pressure is calculated mathematically when talking about molecular impacts.
