A boy ties a stone to the end of a string which he then whirles above his head round a circular path of radius 15cm. if the stone makes 20 oscillations in 10 seconds calculate the angular and linear speeds of the stone.

Ways that industry and agriculture use physical properties to separate substances

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?

The particles that are found in the nucleus of an atom are
