(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

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

In dealing with every task assigned, why is planning important for a student?

Jet001 [13]

Answer:

Having a planner gives students freedom to plan, organize and keep track of their work to the best of their abilities and requirements. This has a dual benefit in that it increases the student's accountability to the commitments planned as well as provides them with a structure that contributes to their success.
