Answer:
Musculoskeletal disorders (MSD) are injuries or disorders of the muscles, nerves, tendons, joints, cartilage, and spinal discs.
Explanation:
We will determine the magnitude of the final component as follows:

So, the magnitude is approximately 8.36.
And the direction will be approximately 57.8° counter-clockwise.
This can be seeing as follows:
Answer:
2.55348650884 m/s
2.67400481907 m/s²
10.6960192763 m/s²
Explanation:
d = Diameter of the ride = 16 ft=
r = Radius = 
t = Time taken = 6 seconds
Velocity is given by

The speed is 2.55348650884 m/s
Acceleration is given by

The acceleration is 2.67400481907 m/s²
When the speed is halved


The acceleration is 10.6960192763 m/s²
Answer:
what a big question I must say
3A) Because the wave speed remains constant
