Sound travels in a medium of density 4.2e3 kg/m3 with a speed of 4.le3 m/s. calculate the bulk modulus of the medium. (1 point) a. 7.06e10 pa b. 5.194e10 pa c. 2.259e10 pa d. 9.736e10 pa e. 11.287e10 pa

Answer : The correct option is, (A)

Explanation :

The formula used for speed of sound wave is:

where,

v = speed of sound wave =

= density of medium =

B = bulk modulus = ?

As the formula is,

Squaring on both the sides, we get:

Now put all the given values in the above formula, we get:

Therefore, the bulk modulus of the medium is

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
