Boy, it has been ages since I have seen/solved one of these.
I am probably mistaken, but I think this might be the way this is solved:
Detemine |X-16| - |X-2| = ? given X<7
0 < |x-16| - |x-2| < 7
I think at this step, the absolute value symbols disappear.
Then solve for x.
Anyone...
Yes, it is possible. Your uncle basically described the use and operation of fiber optics. Fiber optics are (basically) strands of glass optical fibers that are used to carry data signals (such as voice, video) in telecomm. networks. They also typically have a diameter of 60 μm

You know that R (radius of the spherical shell) = 0.750m because the problem stated such.
You know that r (raduis of the field that you are evaluating) is less than R (=0.750m) because the problem statement asked for what the net charge is inside the spherical shell. Which means that r < R...
And I gave the correct answer. With an adequate explanation (I thought). <shrug>
Unless otherwise stated by the problem, there are NO charges (Q) inside the sphere, correct? To further explain my reasoning:
Gauss's law deals with describing the relationship between the net electric flux...
Alright, I should've explained the variables better since I know they change between different text authors. So, here is a brief explanation of the variables I used:
R = radius of the gaussian surface (in this case the sphere has an R of 0.750m.
r = the radius of where you are evaluating...
I know what section of physics you are studying and you should be using Gauss's Law to solve this problem. This is a Gaussian surface problem.
You should have available to you a table of typical electric field calculations using Gauss's Law. And within it you should find:
Charge...
As promised: Here is the link to the pics of the model hovercraft.

Yes, you are correct with that critical feature. The...
Yes, the hovercraft I made was a model (sort of). The chasis was no bigger than 12" x 9" (lxw) and it stood maybe 8" (h). Again, the chasis was made of styrofoam. The motor mounts were made of 1/4" balsa wood. And the entire operation was powered by 2 9V batteries. Give me a day or two and I...
To begin with you will probably need to do a lot of research at your local library to determine the vehicle codes necessary for custom vehicles to be declared road worthy.
For example: You will need to have at least two rear view mirrors, the headlights will need to be at least 24" up from...
Yes, I made a hovercraft just last year. I made it for my senior applied technology class at CSU. The object was to design a hovercraft that is powered by 9V batteries and is capable of moving in a straight line.
I designed the hovercraft using two 9V batteries wired in parallel to two...
I warned all of you that I would return with another review of school texts...
Note: I only have the 2nd volume because I transferred from Cal. State Fullerton to Colorado State University between Physics I and Physics II. So this synopsis will only cover the 2nd half of the (typically)...
are they real people?

I hated chem!

I have to agree with Maximus: Wolverine
I grew up reading Uncanny X-men and Wolverine comic books and he by far stood out the most for me as far a favorites super heroes are concerned.
As for super-villains: Dark Phoenix, Dr. Octopus...
