Solve for the coordinates where lines A and B intersect. A: y=x+4 B: y=0.5x+3.5

The point of intersection is a point where the variables y and x will be the same in both A and B equations. This is because the point of intersection has the same coordinates for both lines. So Y A = Y B an...

Expand (2x+3)^4

We will you use Pascal's triangle in order to find coefficients: 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 so, our coefficients will be 1,4,6,4,1 now, let's expand: (2x+3) 4 =(2x) 4 +4*(2x) 3 3+6 (2x) 2 3 2 +4 (2x)*3 3 ...

In a particle accelerator, you accelerate an electron. Afterwards, you measure it's energy to be 350 keV. Tell my why you can't find the speed from this energy using your knowledge of classical mechanics.

In order to see what the problem is, I will attempt to find this speed. 350keV=5.61 10 -14 J E k =1/2 * m v 2 => v=sqrt(2E k /m) By plugging in numbers, we find that the velocity of the electron, v=3.51 1...
