Not really? I just used the right hand rule and Lenz's law
The Attempt at a Solution
By the right hand rule, outside of loop 1, the magnetic field is out of the page. However, increasing resistance means that field is weakening. We know by Lenz's law...
Uh huh, so let me see if I understand you:
The mass will be 8 times the original mass of the ball due to unvarying density, and radius is doubled. Since $$PE = \frac{-GMM}{R}$$, this equals $$\frac{8^2}{2}$$ = 32 times? Is that correct?
This is for my research project, and for reasons that are too complicated to explain now, I need a numerical answer. I have some evidence based on partial testing that the integral has a closed form solution. This includes the form that I discussed in the second part of my first post
Hey Guys!
I was working on an integration problem, and I "simplified" the integral to the following:
$$\int \limits_0^{2\pi} (7.625+.275 \cos(4x))^{1.5} \cdot (A \cos(Nx) + B \sin(Nx)) \cdot (Z-v \cos(x)) dx$$
This integral may seem impossible (I have almost lost all hope on doing this...
I think you might be a bit confused, so I am going to stray a bit from the notion of "particle"
By Heisenberg's Uncertainty Principle, quantum fluctuations create virtual particles that disappear soon after appearing. Occasionally, as we see in QCD, the energy necessary to produce these...
Note: I know this question has been asked before, but I wasn't allowed to ask my question on that thread
1. Homework Statement
The gravitational self potential energy of a solid ball of mass density ρ and radius R is E. What is the gravitational self potential energy of a ball of mass density...
I did the egg drop project for my class two years ago, and my device was built as followed
I had a cardboard tube where I placed two eggs, with crumpled paper between. On the bottom of the tube, I used 4 straw pieces to build a frame that would be crushed in order to reduce impact on crash...
Yea, I am... Ah, I see, but I still have a problem, if the angular momentum is increasing, how does the ball stop? Does it stop decreasing, and when? I understand that angular momentum increases in the beginning
My question is the following. A ball is initially skidding and eventually starts rolling on a flat plane with friction, and later comes to a halt. Which direction does friction act? (see diagram)
If friction acts to the right, then the translational speed will go up, and that's not right...
Here are different ways of resolving the issue:
Information is irretrievably lost
Advantage: Seems to be a direct consequence of relatively non-controversial calculation based on semicalssical gravity.
Disadvantage: Violates unitarity, as well as energy conservation or causality.
Information...
