1. Density = 13.5 g/mL
Mass = 151 grams
Volume =
What is the volume

density = mass /vol

13.5 =151/ vol

vol = 151/13.5 = 11.2 ml

real, smaller and upside-down.   so the answer should be b.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
