First we have to find L.C.M. of all numbers: 21=3*7 36=2*2*3*3 66=2*3*11 The L.C.M. =2*3*2*3*7*11 =2^2*3^2*7*11 For perfect square of all numbers, we need perfect square of 7and 11: =7^2*11^2 The answer=4*9*49*121 =213444 If you want one more process for

15. ## Intergated chemistry/physics

use conservation of momentum to answer this. --> (m1*v1 of 10lb ball)+(m2*v1 of 6lb ball) = (m1*v2 of 10lb)+(m2*v2 of 6lb) --> 10lb=4.5kg; 6lb=2.7kg --> (4.5kg *2m/s)+(2.7kg*0m/s) = (4.5kg*0m/s) + (2.7kg*v2) -->9+0 = 0+2.7*v2 v2 = 3.33m/s
