The maximum speed is 0.55 m/s
Explanation:
For an object in uniform circular motion, the force of friction between the object and the ground provides the centripetal force required to keep the body in motion. Therefore we can write:

where the term on the left is the frictional force and the term on the right is the centripetal force, and where
is the coefficient of static friction
m is the mass of the body
g is the gravitational acceleration
v is the speed of the body
r is the radius of the circular path
In this problem, we have:

r = 0.102 m

Substituting and re-arranging, we find the maximum speed v at which the salt shaker can rotate:

Explanation:
The electric force acting on a charge is given by:

where
q is the magnitude of the charge
E is the strength of the electric field
In this problem, we have
is the charge
is the strength of the electric field
Substituting into the equation, we find

Answer: Although low frequency sound travels further than high-frequency sound, calls at higher frequencies give the bats more detailed information--such as size, range, position, speed and direction of a prey's flight. Thus, these sounds are used more often.
