A small sphere of radius R is arranged to pulsate so that its radius varies in simple harmonic motion between a minimum of R-ΔR and a maximum of R+ΔR with frequency f. This produces sound waves in the surrounding air of density rho and bulk modulus B. a- Find the intensity of sound waves at the surface of the sphere. (The amplitude of oscillation of the sphere is the same as that of the air at the surface of the sphere.)b-Find the total acoustic power radiated by the spherec-At a distance d≫R from the center of the sphere, find the amplitude of the sound wave. d-At a distance d≫R from the center of the sphere, find the pressure amplitude of the sound wave. e-At a distance d≫R from the center of the sphere, find the intensity of the sound wave. Express your answer in terms of the variables R, x, f, and appropriate constants.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
