Let us have an object that starts at an origin point O and ends at some finishing point F. Distance is the total length of the path taken by the object between O and F, this is also known from our everyda...

There are five major points on a typical metal's stress-strain graph. The first is the limit of proportionality. Prior to this point, the stress strain graph tends to be a straight line, ...

To understand why the drill produces more heat we must understand Lenz's law. Lenz's law states that the direction of an induced current is always such as to oppose the change that causes the current. In ...

By taking the initial vertical speed as v_v = 6 sin(60) = 5.2 ms^-1.The max height of the ball is given by v_v² = u_v² + 2as. From this, s = 1...
