Force@A: FA = mA x g = 35 x 10 = 350NAnticlockwise moment: MA = FA x dA= 350 x 10 = 3500NmForce @B: FB=mb x g = 50 x 10 = 500NC...
The transmitted and reflected waves are of equal frequency and are both continuous, so they will superpose and interfere with each other. In the regions of maximal constructive interference, antinodes wil...
The linear momentum of a particle is defined as the product between the particle’s velocity (a vector) and the particle’s mass (a scalar quantity):p=m·v.The l...
The fastest light can travel is when it is in a vacuum, where it travels at 3x10^8 metres per second. However, when light travels through another substance or material (anothe...
First, be familiar with the equations of motion:s = displacementu = initial velocityv = final velocitya = acceleration (constant)t = timev = u + ats = ((u+v)t)/2s = ut + (at^2)/2v^2 = u^2 + 2as
