Two bumper cars hit in a "non-sticky collision." Before the collision: Momentum of Car 1 = 1,000 kg X m/s Momentum of Car 2 = 200 kg X m/s After the collision: Momentum of Car 1 = 600 kg X m/s Momentum of Car 2 = ? Find the momentum of Car 2 after the collision. Find the total momentum of both cars before the collision by adding them up.

True or false: (a) the strings of little red dots represent carbohydrates. (b) the model is called a bilayer because there are two main types of molecules present, lipids and proteins. (c) the many black lines represent amino acid tails. (d) this model shows membrane transport. (e) the blue ovals are hydrophobic. (f) the blue ovals represent phospholipid heads.
