In a harmonic oscillator with an angular frequency of 5 rad / s, the mass is pulled 2 m from the equilibrium position. Mass t = 0 if at the time x = 1 m; a) Find the phase difference
b) Determine the position equation of the solution of harmonic motion as a function of time.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

true tan speed = ang vel x radius

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

it doesn't. it was imagined up in the middle ages.
