Explanation:
(a) The period of a wave is the time required for one complete cycle. In this case, we have the time of five cycles. So:
(b) The frequency of a wave is inversely proportional to its period:
(c) The wavelength is the distance between two successive crests, so:
(d) The speed of a wave is defined as:
Answer:
Yes, Roberto will have twice the kinetic energy
Explanation:
The equation for kinetic energy is Ke = 1/2(<em>m</em>)v^2
The variable <em>m</em> is not squared by anything, which means it is directly proportional to the equation. If you were to multiply <em>m</em> by 2, it would in turn multiply the entire equation by 2, getting you an outcome with twice as much kinetic energy.
