Answer:
300 clicks...
Explanation:
Output on 3 clicks = 10 dB
Increasing 10 by a factor of 100 equals 1000 dB so,
Its simple math, clicks will also increase in the same ratio and it shall take 300 clicks to increase the volume by a factor of 100.
The velocity of the wave is defined by the product of wavelength and frequency. The velocity of a wave with a length of 10 m and frequency of 5hz will be 50 m/sec.
<h3>What is the velocity of the wave?</h3>
The velocity of the wave is defined by the product of wavelength and frequency. It is obtained from the formula of the wavelength which is given by;
![\rm \lambda=\frac{v}{f} \\\\ \rm v = \lambda \times f \\\\ \rm v = 10 \times 5 \\\\ \rm v = 50\ m/sec](https://tex.z-dn.net/?f=%5Crm%20%5Clambda%3D%5Cfrac%7Bv%7D%7Bf%7D%20%5C%5C%5C%5C%20%5Crm%20v%20%3D%20%20%5Clambda%20%5Ctimes%20f%20%5C%5C%5C%5C%20%5Crm%20v%20%3D%20%2010%20%20%5Ctimes%205%20%5C%5C%5C%5C%20%5Crm%20v%20%3D%2050%5C%20m%2Fsec)
Hence the velocity of a wave with a length of 10 m and frequency of 5hz will be 50 m/sec.

Answer:
437.5Kjoules
Explanation:
K.E=half multiply by mass multiply by square of velocity
=437.5Kjoules
Just took that test the answer is perpendicular to the wave motion
Impulse = Ft = Δmv, where F is the average force, t is time, m is mass and v is velocity.
Δmv = m(v₂ - v₁) = 0.2 * (3 - (-4)) = 0.2 * 7 = 1.4
Solve for F.
