Answer:
![8M(r\pi)^2](https://tex.z-dn.net/?f=8M%28r%5Cpi%29%5E2)
Explanation:
First we convert 2 cycles/s to angular velocity knowing that each circle has an angle of 2π
![\omega = 2 * 2\pi = 4\pi rad/s](https://tex.z-dn.net/?f=%5Comega%20%3D%202%20%2A%202%5Cpi%20%3D%204%5Cpi%20rad%2Fs)
Then we calculate the moment of inertia of the cylindrical shell, assuming there's no mass inside the wheel (only at the rim):
![I = mr^2 = Mr^2](https://tex.z-dn.net/?f=I%20%3D%20mr%5E2%20%3D%20Mr%5E2)
So the kinetic energy of this is
![E_k = I\omega^2/2 = Mr^2*(4\pi)^2/2 = 8M(r\pi)^2](https://tex.z-dn.net/?f=E_k%20%3D%20I%5Comega%5E2%2F2%20%3D%20Mr%5E2%2A%284%5Cpi%29%5E2%2F2%20%3D%208M%28r%5Cpi%29%5E2)
Answer:
Interference
Explanation:
Interference is a phenomenon that occurs when two waves meet while traveling along the same medium.
Answer:
600 N upward
Explanation:
According to Newton's third law, for every action their is an equal and opposite reaction. The equal and opposite reaction to a downward force of magnitude 600 N is an upward force of magnitude 600 N
You've described two (2) axes of motion.
The third one would have been up-and-down.
Answer:
The correct option is;
Amplitude
Explanation:
When transmitting picture signals over the air by broadcasting stations, the signals are shifted into high frequency channels of Very High Frequency (VHF) or Ultra High Frequency (UHF) carrier currents and imposing the the television signal by changing the amplitude of the high frequency carrier current to match the transmitted television signal waveform shape
