100 Hertz
1,000 Hertz
10,000 Hertz
Explanation:
Humans can detect frequencies between 20 Hz and 20,000 Hz.
The distance between the 2nd compression and the 3rd compression in a longitudinal wave is 200 cm. Find the wavelength of the wave.
I need the answer with working and formula..
Class - 8, Ch:13 - Sound, NCERT, CBSE
Explanation:
[tex]3 \times 200 \div 5[/tex]
Answer:
The wavelength of the wave can be calculated using the equation λ = 2L/n, where L is the distance between two compressions and n is the number of compressions. In this case, the distance between compressions is 200 cm and the number of compressions is 3, so the wavelength is 133.3 cm.
Sound waves are moving across the room from the left toward the opening. What happens to the sound waves as they hit the wall with an opening A Some of the sound waves refract off the wall, while other waves will move through the small opening and then spread out. This is called diffraction. B. Some of the sound waves will reflect off the wall, while others will difract trough the opening and spread out. C Most of the sound waves will reflect ofr the wall, while others will diffract through the opening and spread out. D. Most of the sound waves will reflect off the wall, while others will squeeze through the opening and then reflect again.
Answer: C is right
Explanation: Most of the sound waves are reflected back but waves passing opening will speread to all directions outside because of diffraction
What is the formula for displacement?
∆ = xf − xi
v = /
v = ∆/
∆ = v ∙ t
Choose all that apply
What is one cue you need to follow when shooting a basketball?
*please be somewhat detailed *
thanks!
Answer:
We Use The Cue Start Small End Tail. And We Would Use Cues Like "bend knees Push the hips back" "sit back
Explanation:
So We Like Start Small End Tall" Better Because It Not Only Reminds The Shooter To Explode Into Their Shot By Pushing Their Hips Back.
