So a general harmonic equation is Asin(2πt/T). Little t is just a variable. 6 inches is the height of one maximum and one minimum from equilibrium, so that is the amplitude A. T is the period, or the time of one cycle (or wavelength), which is 2 seconds.
The equation is therefore (in terms of seconds and inches), 6*sin(2πt/2), or 6*sin(πt).
If my calculations are correct I think it's 50
Answer:
Simple, 4*pi*r^2
Step-by-step explanation:
I would be happy to help but it seems there are no pictures attached to answer from.
