Answer:

Answer labeled B : 2,304,000 N

Explanation:

Recall the formula for the electric force:

$F_e=9\,\,10^9\, \, \frac{q_1*q_2}{d^2} \\F_e=9\,\,10^9\, \, \frac{8\,10^{-4}*8\,10^{-4}}{0.05^2} \\F_e=2,304,000\,\,N$

which agrees with answer B provided.

Answer:

$B=2.025\times 10^{11}\ Pa$

Explanation:

It is given that,

Speed of P- waves, v = 9 km/s = 9000 m/s

The density of rock is about $2500\ kg/m^3$

We need to find the average bulk modulus of Earth's crust. Let it is given by B. So,

$v=\sqrt{\dfrac{B}{d}} \\\\B=v^2d\\\\B=(9000)^2\times 2500\\\\B=2.025\times 10^{11}\ Pa$

So, the bulk modulus of the Earth's crust is $2.025\times 10^{11}\ Pa$ .
