Answer:
frequency = 5.52 * 10² Hz
Explanation:
the equation that relates velocity, frequency and wavelength is:
velocity = frequency * wavelength
We are given that:
velocity = 331 m/sec
wavelength = 0.6 m
Substitute with the givens in the equation to get the frequency as follows:
velocity = frequency * wavelength
331 = frequency * 0.6
frequency = 331 / 0.6
frequency = 5.52 * 10² Hz
Hope this helps :)
You need to know everything is made of atoms they are always colliding and they are never still because you'd think that every thing in space is still all the time even if it's not making visibly
There's really no "why", because it's not difficult at all.
Simply multiply the number of miles by 1,760, and bada boom,
there you have the same distance described in yards.
The velocity will change (increase) by 9.8 m/s every second.
Why?
Since the ball is accelerated downward at
we can see that the ball is on "free fall". It means that the wall was dropped with no initial speed.
Now, if we want to know by how many meters per second does the object's velocity change every second, we need to understand the units of the acceleration. Let's write the equation of acceleration for better understanding.

So, from the equation we can see that the acceleration is changing the velocity every second.
Hence, if an object has the given acceleration (acceleration due to gravity, 9.8m/s2), it means that its speed will change (increase) by 9.8m/s every second.
Have a nice day!
