The frequency of the wave is 6800 Hz
<u>Explanation:</u>
Given:
Wave number, n = 20
Speed of light, v = 340 m/s
Frequency, f = ?
we know:
wave number = 
Therefore, the frequency of the wave is 6800 Hz
Answer:
D, I think.
Explanation:
I had a quiz in Plate Tectonics and there was 2 questions that are related to this, but not the exact question.
Which material rises from cracks in oceanic crust
-molten rock
Which is the first step in the seafloor spreading process?
-a crack forms in oceanic crust.
those are all right btw, so you can decide if the answer I told you is right or not.
Well it seems like this problem gives you what you need. You said the car was going 4m/s and then accelerated to 60m/s... so 4m/s would be your answer for the initial velocity
Answer:
In physics, if there is biggest mass then the slow down time is more and this effect is basically known as gravitation time dilation. This type of effect can easily be calculated from the different type of metric in the environment.
When some outsider observe then, this effect time seemed to be slowed down. It basically measure the overall amount of the time which elapse at observer distance. Therefore, this is the main concept of the mass slow down time.
