No, light is not the fastest travelling thing in this universe and quantum entanglement fully supports my openion. It is interesting to note that every light sorce converges to a point source as we move a...
This will depend on the conservation laws. In the same way that a numerical equation must be equal on either side, a reaction must have the same amount of certain properties on each side. The properties t...
Magnetic and electric fields share many similarities and symmetries (for example they both act on electric charge and obey an inverse square law of force), but there are some important differences. One di...
If we assume there is no air resistance, this means that the horizontal component of the ball's velocity won't change. Resolving horizontally we can see that the horizontal velocity = ucos(θ). We can ...
relevant equations: F = k*x F is force, k is spring constant and x is displacement from equillibrium.
W = 1/2kx2 W is work done.
rearranging F = k*x and using t...
