Two straight conducting rails form a right angle where their ends are joined. A conducting bar in contact with the rails starts at the vertex at time t = 0 and moves with a constant velocity of 7.00 m/s along them, as shown in Fig 31-44. A magnetic field with B = 0.350 T is directed out of the...

Potential Energy Graph A conservative force F(x) acts on a 2.0 kg particle that moves along the x axis. The potential energy U(x) associated with F(x) is graphed in Fig. 10-46. When the particle is at x = 2.5 m, its velocity is -2.0 m/s. The "kinks" in the graph occur at (1...
I have to determine whether this series converges absolutely, conditionally, or diverges...
\sum^{1}_{\infty}\frac{(-1)^{n}}{n*ln(n)}
I know it converges conditionally (I have the solution in front of me), but it is kind of vague in one area, it says that...

The Attempt at a Solution
I have no idea of how to even approach this... Erm, I fiddled around with the point-slope formula...
Yes, light is a wave, but they ask "The wave phenomenon", I read that as general wave phenomenon rather than light wave phenomenon.
Yes, and thus, it is a wave phenomenon rather than a light wave and thin film phenomenon.
No, of course not, because of the different wavelengths and diferent n values some deconstruct and others don't. So then, a suitable answer would be something like:
Different wavelengths of light bounce off differently, and depending on the thickness of the gasoline, different colors...
I need help with this question:
"Name the wave phenomenon that is responsible for the formation of regions of different color when white light is reflected from a thin film floating on water."
In my handy-dandy high-school physics book, it says that "The different thickness of the gasoline...
What is the point of Newton's First Law? The first law says that "The state of motion of an object will not change unless acted upon by an outside force". In layman's terms, this means that the object's velocity won't change unless there is a net force (at least that is how our physics teacher...
