Subtracting 2 Vectors
This is where things obtain a bit more interesting. What we required to note here is in which in Physics a negative sign simply means "in the opposite direction." We can take A - B and simply modify it into A + -B. The negative sign on the B just means that we will require taking the original vector B and pointing it in precisely the opposite direction (180° from where it's pointing right now. Then we will easily add them just such as we did in the previous diagrams (touching head-to-tail of course!)
why rutherford''s atomic model is failure
This is the virtue of a material resists flow of electric current. It should be as high as possible. When material is subjected to an electrical pressure then will always be a flow
1. A child pulls a toy car weighing 0.20 kg across a smooth floor by means of a string attached to it. If the string makes an angle of 60° to the floor and the child pulls with a f
describe the construction and working of geiger muller counter. give its important application.

The effects of open circuits: An open circuit is essentially a break in the circuit. An open circuit in a series circuit will prevent the flow of current through the circuit. W
A wave front is a line or surface on which the disturbance has the similar phase at every position. If the source is periodic, it generates a succession of ray front, each of the s
Q. What is direction of the current? The path of the magnetic field at the centre of a horizontal current-carrying loop of wire is straight downward. The magnetic field is affe
As electric field is conservation, work done and as potential difference among two points is path independent and depends only on the position of points between which the charge is
