Complete question:
A taut rope has a mass of 0.123 kg and a length of 3.54 m. What average power must be supplied to the rope to generate sinusoidal waves that have amplitude 0.200 m and wavelength 0.600 m if the waves are to travel at 28.0 m/s ?
Answer:
The average power supplied to the rope to generate sinusoidal waves is 1676.159 watts.
Explanation:
Velocity = Frequency X wavelength
V = Fλ ⇒ F = V/λ
F = 28/0.6 = 46.67 Hz
Angular frequency (ω) = 2πF = 2π (46.67) = 93.34π rad/s
Average power supplied to the rope will be calculated as follows
where;
ω is the angular frequency
A is the amplitude
V is the velocity
μ is mass per unit length = 0.123/3.54 = 0.0348 kg/m
= 1676.159 watts
The average power supplied to the rope to generate sinusoidal waves is 1676.159 watts.

Answer:
E) the flow of energy due to a temperature difference.
Explanation:
Heat can be described as the flow of energy due to a temperature difference.
Which is expressed mathematically as;
H = MCΔT
Where;
H is the quantity of heat in a body, measured in Joules
M is the mass of the body, measured in kg
C is the specific heat capacity of the body, J/kg.K
ΔT is change in temperature or temperature difference.
So, heat energy in any system flows from a hotter region to a colder region due to temperature difference.
E) the flow of energy due to a temperature difference.
Answer:
Speed and direction affect pitch.
