Three beads are placed along a thin rod. the first bead, of mass m1 = 24 g, is placed a distance d1 = 1.1 cm from the left end of the rod. the second bead, of mass m2 = 14 g, is placed a distance d2 = 1.5 cm to the right of the first bead. the third bead, of mass m3 = 47 g, is placed a distance d3 = 3.2 cm to the right of the second bead. assume an x-axis that points to the right.

Critical mass is the of material required to produce a chain reaction. a.) minimum amount b.) atomic mass c.) precise amount d.) maximum amount

If forces acting on an object are unbalanced. true or false

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
