The two types of mechanical waves are longitudinal waves, and transversal waves.
Answer:
(a). The average speed is 51.83 m/s.
(b). The average velocity over one revolution is zero.
Explanation:
Given that,
Angular velocity = 110 rev/m
Radius = 4.50 m
(a). We need to calculate the average speed
Using formula of average speed
(b). The average velocity over one revolution is zero because the net displacement is zero in one revolution.
Hence, (a). The average speed is 51.83 m/s.
(b). The average velocity over one revolution is zero.

Answer:
Optical disk.
Explanation:
The optical disk is defined as a storage media containing a flat, compact, and round disk and manufactured with aluminum, acrylic, and lacquer. A laser is used to write and read the optical disks. Audio, film, applications and images were developed specifically to store optical disks.They are generally of two type read only and write/read. Read only format do not allow to write any information to the disk while the other does allow to read information to the disk.
