Answer:
198.2m/s
Explanation:
Speed of a wave(v) is the product of the frequency of the wave (f) and its wavelength(¶).
Mathematically, v = f/¶
Given frequency of the middle C = 261.63Hz
Wavelength = 131.87cm
Converting this to meters we have;
131.87/100 = 1.32m
Speed of the sound = 261.63/1.32
Speed of the sound = 198.20m/s
Therefore the speed of sound for middle C is 198.2m/s
Answer:
0.005 m
Explanation:
length of steel (L°) = 12 m
initial temperature (T) = 16 degrees
expected temperature (T') = 50 degrees
We can find how large the gaps should be if the track is not to buckle when the temperature is as high as 50 degrees from the formula below
ΔL = ∝L°ΔT where
- ΔL = expansion / gap
- ∝ = linear expansion coefficient of steel =
- L° = initial length
- ΔT = change in temperature
ΔL = 
x 12 x (50-16) = 0.005 m
Because it's literally impossible to tell exactly where something that size is
located at any particular time.
And that's NOT because it's so small that we can't see it. It's because any
material object behaves as if it's made of waves, and the smaller the object is,
the more the size of its waves get to be like the same size as the object.
When you get down to things the size of subatomic particles, it doesn't make
sense any more to try and talk about where the particle actually "is", and we only
talk about the waves that define it, and how the waves all combine to become a
cloud of <em><u>probability</u></em> of where the particle is.
I know it sounds weird. But that's the way it is. Sorry.
