In a series circuit, the electrons passes through each component in order before returning to the cell. In a parallel circuit, there are different paths for the electrons to take so the current splits ...
Kinetic Energy (Ek) = 1/2(mv2).This can be rearranged such that, m = (2Ek)/v2we know from the question that Ek = 100 J and we know that v = 15 m/sso ...
Distance is a scalar, meaning it only has a magnitude. Displacement is a vector, meaning that it has both magnitude and direction. For instance, distance can state that I am "x" metres away f...
A.C. stands for alternating current, and the current constantly changes direction. D.C. stands for direct current, and the current only flows in one direction.
Use the equation p= m x v , where p=momentum m=mass (kg) and v=velocity (m/s)p= 84x5 = 420 kg m/s
