The ball is against the vector of gravity. Then, the gravity will be negative.
The ball will stop in the air after approx. 4.72 seconds. And will take the same time to hit the ground.
It will stay approx. 9.44 seconds in the air.
A band director instructs students to play a pitch louder. How will the sound wave change when the band plays the same pitch lou
der?
The speed of the sound wave will increase.
The frequency of the sound wave will increase.
The wavelength of the sound wave will increase.
The amplitude of the sound wave will increase.
The speed of the sound wave will increase.
The frequency of the sound wave will increase.
The wavelength of the sound wave will increase.
The amplitude of the sound wave will increase.
2 answers:
Explanation :
Loudness is defined as how our ear perceives the sound. It is basically related to the intensity of a sound wave.
When the same pitch is played louder, its amplitude changes. Amplitude is the maximum displacement covered by a wave.
This is the only difference between the loudness to that of shrillness. The amplitude of the loud sound is more as compared to that of shrill sound.
So, the correct option is (d).

Answer:
The maximum transverse speed of the bead is 0.4 m/s
Explanation:
As we know that the Amplitude of the travelling wave is
A = 3.65 mm
Now the speed of the travelling wave is
now we know that distance of first antinode from one end is 27.5 cm
so length of the loop of the standing wave is given as
now we have
now we have
now at x = 13.8 cm
now we have
now maximum speed is given as
