If one oscillation has 4.4 times the energy of a second one of equal frequency and mass, what is the ratio of their amplitudes?
Express your answer using two significant figures.
Ahighenergy/Alowenergy
E = kA^2/2
Let k = 2nd spring constant.
(k)A1^2/2 = 4.4(kA2^2/2) ==> A1/A2 = sqrt(9/1)=3:1

What is the ratio of the intensities of an earthquake P wave passing through the Earth and detected at two points 15 km and 49 km from the source? Express your answer using two significant figures. What is the ratio of the amplitudes? Express your answer using two significant figures.
To understand electromagnetic radiation and be able to perform
calculations involving wavelength, frequency, and energy.
Several properties are used to define waves. Every wave has a
wavelength, which is the distance from peak to peak or
trough to trough. Wavelength, typically given the symbol λ
(lowercase Greek "lambda"), is usually measured in meters. Every
wave also has a frequency, which is the number of
wavelengths that pass a certain point during a given period of
time. Frequency, given the symbol...
