Answer:
Sagittarius A
Explanation:
The center of the milky way has a big giant hole known as "Sagittarius A". The size is 4 million times bigger than the sun.
The current atomic model has a predicted area surrounding the nucleus where the electron could be located thanks to quantum physics, subatomic particles makes leaps through space, and an electron could even be a million miles from its nucleus.
So the correct option among the other answer choices are as follows: C.
Answer: D. Diffract
Explanation:
Diffraction is a phenomenon that is based on the deviation of the waves (light waves in this case) when encountering an obstacle.
In addition, it is important to note this phenomenom occurs in all types of waves (ncluding electromagnetic waves).
So, in a general way:
Diffraction happens when a wave (mechanical or electromagnetic wave) meets an obstacle or a slit . When this occurs, the wave bends around the corners of the obstacle or passes through the opening of the slit that acts as an obstacle.
Hence, the correct option is D:
<h3>In order to demonstrate the interference of light waves, the light source emits rays of light, which <u>diffract</u> towards the double slit.</h3>
Answer:
The fundamental frequency and the length of the pipe are 115.8 Hz and 1.48 m.
Explanation:
Given that,
First frequency = 986 Hz
Second frequency = 1102 Hz
We need to calculate the length of the pipe
Using formula of length
Put the value into the formula
We need to calculate the fundamental frequency of this pipe
Put the value into the formula
Hence, The fundamental frequency and the length of the pipe are 115.8 Hz and 1.48 m.
