Answer:
The answer is B.
Explanation:
When you skin your knee, cells divide to replace old, dead, or damaged cells.
(1) wave frequency is the number of waves passing a point at a certain time. Usually, this is expressed in a unit of 1/s or Hz.
f = (600 waves) / (8 hours x 3600 seconds/1 hour) = 1/48 or 0.02 Hz
(2) wave period, T = 1/f
T = 1/48 Hz = 48 s
(3) wave speed
speed = (600 waves)(3 ft/1 wave) / 8 hours
= 225 ft/h
Killing them would be unethical, actually animal cruelty. Unethically changing them in anyway that would harm them would be unethical.
