Your car is traveling at 30 m/s when you press the brake. The car stops after 250 m. Assuming that the deceleration is constant, calculate the time to stop. (a) 16.7 s (b) 17.25 s (c) 9.8 s (d) 35.4 s (e) 12.9 s

Two models of the same compound are shown. in what way is model b better than model a? model b shows the types of elements in the compound, but model a does not. model b shows the three-dimensional shape of the molecule, but model a does not. model b shows how the atoms in the molecule are connected, but model a does not. model b shows the number of atoms of each element in the molecule, but model a does not
