The displacement is just the distance between the starting point and the
ending point, and you don't care about the route taken or the actual distance
covered along the way.
This can bite you sometimes. For example, some day you'll be given the
diameter of a circle, and you'll be asked for the displacement of an ant that
walks around the circle 17 times and finally stops at the same place it
started from. You might go to work calculating the circumference of the
circle and multiplying it by 17. But if you think about it first, you realize that
if the ant ends up at the place he started from, then his displacement is zero.
Pitch is the sensation of certain frequencies to the ear. High frequency = high pitch, low frequency = low pitch.
f = c(speed of the wave) / <span>λ (wavelength)
1. 343m/s / 0.77955m = 439.99 Hz
This corresponds to pitch A
2. 343m/s / 0.52028m = 659.26 Hz
</span> This corresponds to pitch E
<span>
3. 343m/s / 0.65552m = 523.349 Hz
</span>This corresponds to pitch C
4. using f = c / λ
λ = c / f<span>
= 343m/s / 587.33 = 0.583999 m = 0.584 m

Answer:
You could move something across the Earth with a little push. It would make fuel really efficient on those pathways. You could make a floor that is impossible to walk on. Everybody would just fall without traction.

Answer:
The equation which define the work done by spring is w = 45 x³ - 8 x²
Explanation:
Given as :
The force is the function of distance x
I.e F(x) = a x² - b x
where
a = 45 N/m²
b = 8 N/m
Now, Wok done = Force ×displacement
I.e W = F . ds
So , W = (a x² - b x) × x
or, W = (45 x² - 8 x) × x
Or, w = 45 x³ - 8 x²
So, the equation which define the work done by spring is w = 45 x³ - 8 x²
Hence The equation which define the work done by spring is w = 45 x³ - 8 x² Answer
