Hiii please help me At the end of a very long taut string, of mass 0.008 kg, and linear density 0.021 kg / m, a MAS is produced, perpendicular to the direction of the string, of amplitude 0.322 cm and frequency 16 Hz. If this disturbance propagates along the rope with velocity 43m / s, determine:
a. the wavelength of the generated waves.
B. The energy that these waves transmit.
C. The power that transmits the waves produced along the string.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.

not too sure thinking all accelerations are pointed down
