Sphere A has mass m and velocity +3v so its initial momentum is 3mv. Sphere B has mass 2m and velocity -v so its initial momentum is -2mv. Therefore we can say:3mv - 2mv = M_cv_c, wher...

Conservation Laws are useful because they establish fixed rules that physical interactions must follow, which helps physicists to better understand these processes. In particular, they provide a picture o...

First of all you need to know that learning a language is not easy, so do not worry if sometimes you are struggling with it. It is important to practice as much as you can, to do the homework in the targe...

When finding the gradient of a line we need to first locate any two points, on the line, where we know the x-coordinates and we know the y-coordinates. Now, with these two coordinates we need to find two ...

Markovnikov's rule states that, during electrophilic addition to alkenes/alkynes, the hydrogen atom in the electrophile will be added to the carbon atom in the alkene/alkyne that is bonded to he most hydr...
