Different things motivate different people. While you may be motivated to get good grades and get a scholarship to an Ivy League college after high school, your classmate's motivation might be to finish high school and go backpacking around the world. Do some research on the Internet and at the school library, and write about the four different types of external and internal motivations: extrinsic, intrinsic, identified, and introjected, and provide examples for each. Also, consider a situation in which you were highly motivated (it does not have to be academic), and describe your motivation and the outcome of the situation.

The frequency of vibrations of a vibrating violin string is given by f = 1 2l t Ο where l is the length of the string, t is its tension, and Ο is its linear density.β (a) find the rate of change of the frequency with respect to the following. (i) the length (when t and Ο are constant) (ii) the tension (when l and Ο are constant) (iii) the linear density (when l and t are constant) (b) the pitch of a note (how high or low the note sounds) is determined by the frequency f. (the higher the frequency, the higher the pitch.) use the signs of the derivatives in part (a) to determine what happens to the pitch of a note for the following. (i) when the effective length of a string is decreased by placing a finger on the string so a shorter portion of the string vibrates df dl 0 and l is β f is β (ii) when the tension is increased by turning a tuning peg df dt 0 and t is β f is β (iii) when the linear density is increased by switching to another string df dΟ 0 and Ο is β f is β
