In 1980, over San Francisco Bay, a large yo-yo was released from a crane. Suppose the yo-yo was 108 kg, and it consisted of two uniform disks of radius 40.0 cm connected by an axle of radius 4.00 cm. What was the magnitude of the acceleration of the yo-yo during (a) its fall and (b) its rise

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
