How are casts formed by decaying organisms? O Organisms turn into rock over time.
O Organisms leave carbon residue on a rock.
O Organisms leave impressions in sediment that hardens into rock.
O Impressions left by organisms are filled in with sediment that hardens into rock.

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,?
