Is intensity of sound subjective or objective in nature ?

An object is subjected to an acceleration a = 4 + 3v . It is given that the displacement S = 0 when v = 0 . The value of displacement when v = 3 m//s is

To participate in a discussion, one should read the topic, A. Critically B. Objectively and subjectively C. Superficially D. Constructively

An object is subjected to retardation, (dv)/(dt)=-5sqrtv , which has initial velocity of 4ms^(-1) . The time taken by the object to come to rest would be

An object is subjected to a force in the north-east direction. To balance this force, a second force should be applied in the direction

Find the minimum magnification of a microscope, whose objective's numerical apertune is sin alpha = 0.24 , at which the resolving power of the objective is totally employed if the diameter of the eye's pupil is d_(0) = 4.0mm .

There is a microscope whose objective's numerical aperture is sin alpha = 0.24 , where alpha is the half-angle subtended by the objective's rim. Find the minimum spearation resolved by this microscope when an object is illuminated by light with wavelength lambda = 0.55 mu m .
