###### The chin-up is one exercise that can be used to strengthen the biceps muscle. This muscle can exert a force of approximately $8.00 \times 10^{2} \mathrm{N}$ as it contracts a distance of 7.5 $\mathrm{cm}$ in a $75-\mathrm{kg}$ male. $^{3}$ . How much work can the biceps muscles (one in each arm) perform in a single contraction? (b) Compare this amount of work with the energy required to lift a 75 -kg person $40 . \mathrm{cm}$ in performing a chin-up. (c) Do you think the biceps muscle is the onl

##### Natural crystals of tartaric acid will rotate polarized light in a specific direction, while synthetically made crystals do not. In 1849 Louis Pasteur deduced that this "optical activity" was due to the existence of two distinct isomeric forms of tartaric acid, leading to the discovery of chirality in molecules. The formula of tartaric acid is Using wedged bonds, sketch the two optical isomers of a tartaric acid molecule.
