Answer: Seismograph is an instrument that is used to measure the vibration of the earthquake. It is based on seismic waves. X ray is an electromagnetic energy wave that is used for CAT ( computerized axial tomography) scan.
Hence, both seismic wave and X ray are energy waves.
The velocity of seismic waves is different in different media. Similarly, X ray loses its amplitude depending upon the dense layer of the tissue.
Answer:
The final angular speed of the carousel is 1.68 rad/s.
Explanation:
This is simply a conservation of angular momentum problem.
Combining the two equations yields the angular momentum of the carousel after the man climbs.
