A wave is traveling at a speed of 12m/s and its wavelength is 3 m calculate the wave frequency
White raven [17]

Answer:

f = 4 Hz

Explanation:

Given that,

The speed of a wave, v = 12 m/s

The wavelength of a wave, \lambda=3\ m

We need to find the frequency of the wave. We know that the speed of wave is equal to the product of wavelength and frequency. So,

v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{12}{3}\\\\f=4\ Hz

So, the frequency of the wave is equal to 4 Hz.

Suppose an elephant has a mass of 2850 kg. show answer No Attempt How fast, in meters per second, does the elephant need to move
Bad White [126]

Answer:

1.23 m/s

Explanation:

The kinetic energy of the sprinter is:

KE = 0.5 * m(s) * v²

KE = 0.5 * 77 * 7.5²

KE = 2165.63 J

If the KE of the sprinter and the KE of the elephant are equal, hence:

2165.63 = 0.5 * m(e) * v²

2165.63 = 0.5 * 2850 * v²

=> v² = 1.52

v = √(1.52)

v = 1.23 m/s
