A sculptor is sharpening a chisel on grindstone of radius 1.0 m that is spinning with a constant angular speed of 2.0 rad/s. What is the magnitude of the centripetal acceleration of a point on the rim of the grindstone?

centripetal acceleration will be equal to 4      

Explanation:

We have given radius r = 1 m

Constant angular speed

We have to find the centripetal acceleration

Linear velocity id equal to

Centripetal acceleration will be equal to

So centripetal acceleration will be equal to 4

reserve is the answer

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
