A0.25 kg ideal harmonic oscillator has a total mechanical energy of 9.8 j. if the oscillation amplitude is 20.0 cm, what is the oscillation frequency? a. 4.6 hz b. 1.4 hz c. 2.3 hz d. 3.2 hz

7.04 Hz

Explanation:

x(t) = A cos(wt)

v(t) = - wA sin (wt)

Vmax = wA

E = 1/2 * m * (Vmax)^2

E = 1/2*m*(wA)^2

f = w/ 2*pi

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
