We all know the question: why do I need to know this? I have been thinking recently about how to add relevance to my curriculum. What I am struggling to come to grips with is how knowing physics, the topics typically taught in a high school intro course, can be useful in everyday life. I am not...
Ok, good you used the right equations and got the velocity and position vectors. Now, how is speed and distance related to velocity and position vectors? Think about whether speed and distance are vectors or scalars.
What kinematics equations do you know that might apply to this problem? There is one that involves only velocity, acceleration and time which is useful for the first part.
Then there is also an equation involving position position, velocity, acceleration, and time which helps you solve the...
ok, so I reread the online source, first the exponential should be a power function in the form r^{n} and r^{-n} and then the r^{-n} term should be removed because this blows up when r=0.
I saw somewhere online that the Fourier series expansion can be used to find the coefficients. If you notice, the solution with only the e-n term but including both the sine and cosine terms resembles the Fourier series expansion. Then the coefficients can be found using the formula to find the...
I am currently working on the same problem exactly and I came up with the same general solution. I tried to apply the boundary conditions when r=a, but that got me nowhere useful and I can't think of any other useful boundary conditions to apply.
The only place where I was able to eliminate...
You can derive the Sackur-Tetrode equation by solving for the entropy of an ideal gas using Stirling's approximation applied to the multiplicity formula. My thermodynamics text does not go through the whole derivation, but that is how it says to derive it.
First off, think about what forces will act on block M2. What force do you think would cause it to accelerate, what force is missing that you think would not cause acceleration? Why?
I am not positive but it seems like your intuition about a magnified image being far from your eye mean that is would not be as magnified. The one thing I will say is that things a more complicated when you include your eye because your eye contains a lens. So, now you have two lenses in the...
1. Work can go into many things, a change in GPE being only one. In your problem there would also be a change in kinetic energy which is where the extra 100J went.
2. The comb will gain and excess of one type of charge. The molecules in the water will rotate to align themselves with the...
What do you think happens?
Obviously boiling, freezing, melting points are linked to a specific temperature. What relationships does pressure have to temperature?
How do you think impurities would affect the properties of a material?
At the instant that the biker leaves the ramp what is the angle of the velocity vector? that is whi phi is the right angle to use. Also, why do you think that it should be some other angle?
Maybe i am totally misunderstanding what you are asking
=The x in F=-kx is actually a \Deltax, the correct equation is F=-k\Deltax, which is the difference between the current length of the spring and the equilibrium length.
Then, if you wanted to set up the integral, yes, it would be...
