Answer:
Wavelength.
Explanation:
1 period, or wavelength, is measured from one crest to another or from one trough to another.
A common misconception is that scientific theories are rudimentary ideas that will eventually graduate into scientific laws when enough data and evidence have been accumulated. A theory does not change into a scientific law with the accumulation of new or better evidence.
For an object in circular motion, the centripetal force is given by:
where
m is the mass of the object
v is the tangential speed of the object
r is the radius of the circular path
Therefore, we see from the formula that there are three physical quantities that affect the value of the centripetal force: the mass of the object, its speed and the radius of its orbit.
Downward force = gorce of gravity (her weight)
= 55 x 9.8 = 539 newtons / / / Upward force = 825 newton. / / / Net force = 825 - 539 = 286 newtons upward. / / / F = m a / / / a = f / m = 286 / 55 = 5.2 meters per second squared Upward. / / / Note: We don't know the length of her fall before the bungee kicks in. At the moment we're dealing with, when her acceleration is 5.2 m/s-squared Upward, her velocity can very well be Downward.
