    Question about right hand rule for physics

    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...

    Question about right hand rule for physics

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

    Question about right hand rule for physics

    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...

    Question about right hand rule for physics

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

    Question about right hand rule for physics

    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...

    Pressure in a liquid without gravity

    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...

    Pressure in a liquid without gravity

    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...

    Solids and Liquids in Hetrogenous Equilibrium

    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...

    Solids and Liquids in Hetrogenous Equilibrium

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

    Solids and Liquids in Hetrogenous Equilibrium

    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...

    Why can this formula be applied for diffraction gratings?

    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...

    Calculating Work Done by a Batter on a Baseball

    I think your teacher is confusing work with impulse.

    Why Is Diffraction More Evident When Slit Width Matches Wavelength?

    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...

    Why Is Diffraction More Evident When Slit Width Matches Wavelength?

    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...

    Gas pressure and container shape.

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