Answer:
Waves superimpose upon each other when they collide, while objects do not
Step-by-step explanation:
The main difference between the collision of waves and the collision of objects is simply the superposition principle.
When waves collide, they do not do so in the same way objects do. The superposition principle explains that waves can either collide in a constructive or destructive manner.
Case A: Waves colliding in a constructive manner
When waves collide in a constructive manner, this means that they are in phase, in simpler terms, it means that they have the same shape as they move through space-time. Constructive collision leads to a formation of a bigger wave with a higher amplitude. This is how stereo speakers operate. They produce louder sounds by releasing the same audio waves, causing them to superimpose upon each other.
Case B: Waves colliding in a destructive manner:
When waves are out of phase(i.e do not have the same shape as they move through space-time) and they collide, they try to cancel each other out, leading to a new wave with a weaker amplitude. This is how noise-cancelling headphones work. They emit an equal and opposite wave sound to the noise around your ears, thus cancelling it out.
Answer:
chance or 12.5% chance
Step-by-step explanation:
2 male <em>percussionists</em>
2 female <em>percussionists</em>
3 male <em>woodwinds</em>
<u>2 </u><u>female</u><u> </u><u><em>woodwinds</em></u>
4 male <em>brass players</em>
3 female <em>brass players</em>
We're looking for a female <em>woodwind. </em>Now there is only 2 of them so we get the female woodwinds out of all the jazz band members or 
or or 12.5% chance.
Answer:
The mean score is 87
Step-by-step explanation:
79x2=158
158-71=87
Answer:
61
Step-by-step explanation:
- 13 - 1 = 12
- 12 ÷ 2 = 6
- Put 6 and 1 together: 61
Therefore, the number is 61
Let's check:
- 6 × 2 = 12
- 12 + 1 = 13
The sum of the two digits is 13, and we got that, so we are correct. The number is 61.
Answer:
5,376in^3
Step-by-step explanation:
find the volume of the smaller box first
10×4×12 = 480in^3
find volume of bigger box
17×12×24 = 4,896in^3
add both volumes 4,896 +480 = 5,376in^3
