miss Akunina [59]

Answer:

1) $\lambda = 11\times 10^{-4} m$

2) $2.51\times 10^9 Pa$

Explanation:

Given data:

speed of sound v = 1540 m/s

frequency f = 1.40 MHz = 1.40 \times 10^6 Hz

density $\rho = 1060 kg/m^3$

1) we know that

$v = f\lambda$

$\lambda = \frac[v}{f} = \frac{1540}{1.40\times 10^6}$

$\lambda = 11\times 10^{-4} m$

2) we know that

$v= \sqrt{\frac{modulus}{density}}$

$v^2 = \frac{\gamma}{\rho}$

$\gamma = v^2 \rho$

$\gamma = 1540^2 \times 1060 = 2.51 \times 10^9 Pa$

Describe the cause of earth's magnetism ?

Ksivusya [100]

The magnetic field of Earth is caused by currents of electricity that flow in the molten core. ... The currents flow in the outer core, and the lines of force shown in yellow, travel outwards through the rest of the earth's interior. If the earth rotated faster, it would have a stronger magnetic field.

olga2289 [7]

In the context of variables and measurement scales, the magnitude of the differences between the numbers on the scale is meaningful interval scale.

<h3>What is an interval scale?</h3>

It should be noted that an interval scale means a measurement where the difference between the variables is meaningful and equal.

In this case, in the context of variables and measurement scales, the magnitude of the differences between the numbers on the scale is meaningful interval scale.
