I've heard of a few career types in science such as engineering, astrophysics, theoretical physics, and basic ones like that, but I was wondering if someone could give me a more detailed list of careers or break down some of them. Such as is it just theoretical physics or is it broken up into...

That's what I had been asking, if it was possible to find it. The coefficients of friction are static = .63 and the kinetic = .54, the gravitational acceleration is 9.8m/s^2, ratio between the masses js 1:1, and the tension on the rope is what I have been asking about.

The only things that are given are the masses are equal, and the friction forces. You also know the gravitational acceleration but that doesn't get s numerical answer, all we could get was F=9.8m but I want a numerical value for the tension force

Homework Statement The system to the right has two identical masses. (one is hanging off the ledge of a table, one is on the table, they are connected by a rope.) tge coefficients of kinetic and static friction are .54 and .63 respectively. Find the acceleration and the tension in the rope...

What is my misunderstanding then? I thought the string firce was what held the particles together against the repulsive electrostatic force

I got to wondering about this the other day so I tried looking it up but I could not find anything. All j could find was that it had a maximum force of 10,00N. I tried to calculate the electrostatic force of a helium atom because if the strong force has to hold the atoms nuclei together jt has...

Homework Statement I have 2 protons 1 femtometer away from each other, what is the repulsive force between them? q1 = 1.6x10-19C q2 = 1.6x10-19C r = 1x10-15m K = 9x109Nm2/C2 Homework Equations FE=Kqqqw/rw The Attempt at a Solution My answer comes out to be -230.4N but I...

It has to be battery and as I said earlier, I need the 5v to go through a 5v/12v dc/dc converter, so 5v goes in and 12v comes out but I also need the converter to output 2A so I need around 5-6A to go into the converter for it to output the required 2A, the power from the USB ports will be on...

No I'm not connecting the converters in parallel I only have 1 converter, what I'm doing is I'm taking 2 USB cables (just normal USB cables with the standard 2 power wires and 2 data wires) and plugging each if them into separate USB ports on the battery pack. Then I will take the ends of both...

So I need 2A to get through a 5v/12v converter, so from what I understand I'll need around 5-6A, if I take a portable battery pack (the ones with multiple USB ports for charging devices like phones and such) and put a plug in 2 if them, then strip the other end of both the cables and connect...

Would it actually be possible to do what he did and track a criminal back to an origin point like that?

I I was watching something the other day and using math they were able to trace droplets of water back to an origin point (they used that I then find the origin of a rapist but I don't know about that being realistically possible) but they didn't say what it was called that they were doing...

It's ability to convert the fuel into energy, we convert almost none of uranium into energy, but from what I've read we can convert a large amount if the thorium into energy but from what people on this post have said I'm starting to doubt everything I've read haha.

But the point of a nuclear reactor is to generate energy, nt to create bombs, well I mean the government doesn't see it that way but if you exclude the bomb making would lftr be more efficient?

So is it also not true that they are safer that a common nuclear reactor? I had heard that they were safe to be built in a higher density population area but if they met gamma rays then that wouldn't be true, also is this video inaccurate then? https://m.youtube.com/watch?v=nYxlpeJEKmw
