3. (a) through (d) show all your calculations and units as
applicable. You will be assessed both on your answers and your
explanations of how you got them.
(a) What is the frequency of a light wave that has a wavelength
of 4449 nanometers?
(b) How many joules of heat are required to change 234grams of
solid ice with a temperature of 260 Kelvin into that many grams of
liquid water with a temperature of 300 Kelvin? [For this question,
you may use 273 Kelvin as the melting point of ice.] (
c) If a spring attached to a mass of 23.4 kilograms is
oscillating with simple harmonic motion with a period of 1.4
seconds, then what is its spring constant?
(d) If a battery contains 2700 milliAmp-hours (mAh) of charge,
how much total energy can it deliver while operating an electrical
device at 25.42 volts
