That depends on the wavelength of the electromagnetic radiation.
-- If the waves are long, then we use them for radio, TV, and cellphones.
-- If the waves are shorter than that, then we use them for GPS in the car.
-- If the waves are shorter than that, then we use them to heat meatloaf
in the microwave oven.
-- If the waves are shorter than that, then they warm us and they
make our plants grow ... like the ones we eat.
-- If the waves are shorter than that, then our eyes use them to see with.
-- If the waves are shorter than that, then they tan our skin.
-- If the waves are shorter than that, then they can cause cancer on
our skin.
-- If the waves are shorter than that, then they can cause cancer and
other diseases in places inside our body.
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:
