What if? you hang a spring with spring constant k = 100 n/m from the rear view mirror of your car. what is the mass (in kg) that needs to be hung from this spring to produce simple harmonic motion with the same period as the bump on the tire?

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.

a. are

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
