Answer:
They two waves has the same amplitude and frequency but different wavelengths.
Explanation: comparing the wave equation above with the general wave equation
y(x,t) = Asin(2Πft + 2Πx/¶)
Let ¶ be the wavelength
A is the amplitude
f is the frequency
t is the time
They two waves has the same amplitude and frequency but different wavelengths.
F=m*a
F=65 kg *9.8 m/s^2
F=637 N (Newtons) — this is the weight
The two most common units of electric energy is Watts or hertz.
First you do 2.5 n-m / 2 kg-m2
This equals 1.25 rad/s^2
Then multiply rad/s^2 by 10 because of the amount of seconds
This equals 12.5 rad/s^2
Then do this following equation : (1/2)Iwf^2
Do (0.5) 12.5 * 12.5 * 2
This equals 156.25 J (meaning that the answer is C: 156 J)
