<u>Answer: </u>
Metal ball will take 0.364 seconds to reach floor.
<u>Explanation: </u>
Initial height from ground = 65 cm = 0.65 meter
We have equation of motion , , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
In this the velocity of body in vertical direction = 0 m/s, acceleration =acceleration due to gravity = 9.8 , we need to calculate time when s = 0.65 meter.
Substituting
So it will take 0.364 seconds to reach floor.
The sound of a lamb is <u>grave </u>due to its <u>high </u>pitch depending on its <u>low </u>frequency. Option B is correct.
<h3>What is the frequency of the sound?</h3>A sound pressure wave's frequency is the number of times it repeats itself every second.
The frequency of the sound is the inverse of the period. If the wavelength of a wave is short. The wave will indeed have a lower frequency. A longer wavelength denotes a lower frequency.
Pitch and the frequency of sound are inverse to each other. A lamb's sound is grave because of its high pitch and low frequency.
The sound of a lamb is <u>grave </u>due to its <u>high </u>pitch depending on its <u>low </u>frequency.
Hence, option B is correct.
