a stone attached to 1m long string is moving with the speed of 5ms in a circle find the centripetal acceleration of the stone​

The centripetal acceleration of the stone is 5 m/s²

Explanation:

The length of the string to which the stone is attached, r = 1 m

The speed with which the string is rotated, v = 5 m/s

The centripetal acceleration, , is given as follows;

Therefore, the centripetal acceleration of the stone found as follows;

The centripetal acceleration of the stone, = 5 m/s².

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
