Guitar string has a frequency of 440 Hz and a damping time of 2.2 sec. How many oscillations does the string make before the oscillation amplitude has decreased to half of the original value? If the initial amplitude of the guitar string was 1.9 mm, how large will be the amplitude after 2.1 sec, 4.2 sec, and 8.4 sec?

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
