When you pull a small tree to one side and suddenly let it go, it swings back and forth several times. You notice that the period of this motion doesn't depend on how far you bend the tree away from its normal upright position. Based on that observation, you know that the restoring force that returns the tree to its upright position is:.

Explanation:

The period of oscillation of a SHM does not depend upon the amplitude of oscillation . But the restoring force depends upon the displacement . When the displacement is equal to amplitude , restoring force is the highest . this is the reason why in SHM , acceleration or deceleration depends upon the displacement from the point of equilibrium . Though time period remains the same.

Time period depends upon the elasticity of the material which creates restoring force and the mass of the body on which the restoring force acts.

Hence in the present case

the restoring force that returns the tree to its upright position is proportional to displacement from its equilibrium position.

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.

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c.m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
