E = ½KA^2 is the mechanical energy of any oscillator. It is the sum of elastic potential energy and
kinetic energy. When amplitude A
decreases by 3%, then
(E2-E1)/E1 = {½K(A2^2/A1^2) }/ ½K(A1^2)
= {(A2^2 – A1^2) / (A1^2)}
= 97^2 – 100^2/100^2
= 5.91% of the mechanical energy is lost each cycle.
Answer:
Explanation:
Let the distance be d . When sound travels d and is reflected back , it is heard by person as echo . Time taken by sound to travel total of distance 2 d
= 2 d / v where v is velocity of sound.
When this time is .05 s at least , echo will be heard . velocity of sound in air 340 m /s
so for echo to be heard ,
2 d / 340 = .05
d = 340 x .05 / 2
= 8.5 m .
A form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.
