(8%) Problem 3: Sound in water travels at a velocity governed by the relation v = √(B/rho) where B is the bulk modulus and rho i
Fittoniya [83]

Answer:

the time required for the sound to travel between the whales 0.66 S.

Explanation:

As given in the problem, the velocity of sound wave (v) is governed by the equation

v = \sqrt{\dfrac{B}{\rho}}

Given, B = 2.38 \times 10^{9} Pa and \rho = 1046 Kg m^{-3}

So for salt water, the velocity of sound wave (v_{s}) can be written as

v_{s} = \sqrt{\dfrac{2.38 \times 10^{9}}{1046}} ms^{-1} = 1.508 \times 10^{3} ms^{-1}

As the whales are d = 1 Km or 1000 m apart from each other, so the time (t) required for the sound wave to travel this distance is given by

t = \dfrac{d}{v_{s}} = \dfrac{1000 m}{1.508 \times 10^{3}} = 0.66 s

Given the position vector of the particle
Natali [406]

With position vector

\vec r(t)=(t+1)\,\vec\imath+(t^2-1)\,\vec\jmath+2t\,vec k

the particle then has velocity

\vec v(t)=\dfrac{\mathrm d\vec r(t)}{\mathrm dt}=\vec\imath+2t\,\vec\jmath+2\,vec k

and acceleration

\vec a(t)=\dfrac{\mathrm d\vec v(t)}{\mathrm dt}=\dfrac{\mathrm d^2\vec r(t)}{\mathrm dt^2}=2\,\vec\jmath

Then t=1, then particle's velocity and acceleration are, respectively,

\vec v=\vec\imath+2\vec\jmath+2\,\vec k

and

\vec a=2\,\vec\jmath
