^ Very helpful. Thanks!

After watching about 20 youtube videos, I think I need to take 1/(1/2)^2 and I get 4N as my new force. I still don't understand how exactly this fits into the equation, but I am going to accept this answer with my lack of conceptual reasoning. Can someone explain to me what would happen if...

How am I expected to find the new force without a given distance??

The ratio of the new distance is 1:1? How is that ratio equal to 1/2? When I plug this into my equation, how to I solve from: 1N=k(Qq/d^2(1/2)) I know that as my distance gets cut in half, my 1N will expand because of the inverse relationship.

I still don't understand what this means. So I take d^2 (even though I don't know what d is) and then take its inverse which means d^2= square root of d^2/1?? The thing I have always hated about physics and my brain is I don't see the connections that everyone else sees... How do you know what...

Homework Statement If two charged bodies attract each other with a force of 1 Newton, with what force will they attract each other if the distance between them is reduced to one-half of its original size? (The “Newton,” abbreviated by the letter N, is the unit of force in the metric system...

How do I take (2/3) x (3 x 10^8)?

I get confused when converting. I understand now why I need to multiply by 2 but how exactly do I arrive at 36x10^6? Could you explain this part in more detail please?

Radio waves travel at the speed of light. A satellite is in a "geosynchronous orbit." A radio signal is sent from the ground to the satellite and then the satellite sends the signal back down to the ground. Satellites in geosynchronous orbit are 36,000km above the surface of the earth. How much...

I didn't forget it in my notes.. I just forgot to type it out after simplifying. Basically, I'm stuck on what my next step should be from (2.99792458 x 10^8)(3600)/1609. Should I just type this into the calculator from here? Or is there additional simplification?

The speed of light is 2.99792458 x 10^8 meters/second. What is this speed in miles per hour? (There are 1609 meters in one mile). I used dimensional analysis to get here:(2.99792458 x 10^8 meters/second) * (1 mile /1609 meters) * (3600 seconds / 1 hour) My question is, what do I do with...
