Answer:
.018 M
Explanation:
grams/MM=ans./volume(L) = M
4/58.45=ans./3.8=.018 M
<h2>Answer:</h2>
It means the waves collides and constructive interference occurred.
<h3>Explanation:</h3>
If the two waves coming from the opposite direction collide with each other, there are two way of their interference.
- Constructive interference: An interference which results in the increase in energy. And it is when crust of a wave comes on the crust of second wave.
- Destructive interference: An interference which results in decrease in energy of the resulting wave and colliding waves cancel the result of each other.
Hence in experiment there will be constructive interference.
"Increase Pressure " is the right answer. if you need help , let me know
They are different measurements
