What angular speed (in revolutions/second) is needed for a centrifuge to produce an acceleration of 1 000 g at a radius arm of 15.0 cm?

a. 40.7 rev's

b. 75.4 rev/s

c. 81.4 rev/s

d. 151 rev/s

a. 40.7 rev's

Explanation:

"Centrifugal force" is the apparent force that a non-inertial observer seems to perceive as a result of the non-inertiality of his reference system. Therefore, in this case we must work with an equivalent force, that is, the centripetal force, which is given by:

The centripetal acceleration is defined as:

The linear speed is given by:

So, we have:

volts times amps 6 x 0.5 3w

it is a negative acceleration
