Answer:
D. 12 cm
Explanation:
A node is a point on a standing wave that does not vibrate.
The nodes of a standing wave are shown in the following sketch.
The red dots are the nodes of the standing wave.
It is observed that the distance between two adjacent nodes is half the wavelength of the wave.
Therefore, if the wavelength of the wave is 24 cm, then the distance from one node to the net must be 24 / 2 = 12 cm.
Hence, choice D is the correct answer.
The answer is B, because all energy is released at once in static electricity.
There’s a quizlet that mentions these questions, if you are having trouble. I’d suggest to give them a look.
Answer:
1.28 x 10^5 Pa
Explanation:
The absolute pressure at the bottom of the tank of water is given by:
where
is the atmospheric pressure
is the water density
g = 9.8 m/s^2 is the acceleration of gravity
h = 2.50 m is the heigth of the column of water
Substituting into the formula, we find
