Oh, okay, thanks Longstreet, now I understand. If we assume that the weight is set (not thrown) on the cart, we could say that there is an inelastic collision occurring with the initial velocity of the weight being negligibly small (giving it a negligibly small initial momentum). Pi = Pf Pci...

I kind of confused about this physics question. Assume for example a 1 kg cart is moving at a constant speed of 5 m/s on a frictionless service. Then, a 1 kg weight is dropped onto the cart. Would its initial momentum be conserved? What would be it's final velocity? At first, the cart has...

Blood is definitely a heterogeneous mixture because it is a colloid. It is made up of different microscopic material that does not occur uniformly throughout; therefore, it is not homogeneous. Dry ice is a pure substance because it is made of a single compound. You are right about krypton...
