In a system of three particles, the linear momenta of the three particles are (1,2,3), (4,5,6) and (5,6,7). These components are in kgms^(-1) . If the velocity of centre of mass of the system is (30,39,48)ms^(-1) , then find the total mass of the system.

If A={5,6,7} and B={7,8,9} then A uu B is equal to a) {5,6,7,8,9} b) {5,6,7} c) {7,8,9} d) None of these

The projection of the line joining (2,3,4) and (5,6,7) on the plane 2x+y+z=1 is: -

Evaluate: (5.67 xx 5.67 xx 5.67 + 4.33 xx 4.33 xx 4.33)/(5.67 xx 5.67 - 5.67 xx 4.33 + 4.33 xx 4.33)

The projection of the line joining (2,3,4) and (5,6,7) on the plane 2x+y+z=1 is sqrt(k) then k=
