A biologist took a sample of chlorophyll (used for photosynthesis) from the leaf of a plant and ran it through a spectrometer, Which of the following is a reasonable conclusion from the data? The chlorophyll would not appear blue to the naked eye, because it is allowing blue wavelengths to transmit through.

The chlorophyll would appear blue to the naked eye, because it is allowing blue wavelengths to transmit through.

The chlorophyll would appear red to the naked eye, because it is allowing red wavelengths to transmit through (different question)​

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
