We now divide the number of revolution in radians by the time in minutes.
Answer:
9.8 m/s2
Explanation:
In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2.
Got it from the internet, hope it helps though ^^
If the domains of ferromagnetic are oriented randomly, THE MATERIAL IS NON MAGNETIC.
The magnetic properties exhibited by some elements is due to the motion of their electrons at the atomic level. Ferromagnetic materials have different domains, when these domain are oriented randomly, they cancel one another out and the material become non magnetic.
