In certain ranges of a piano keyboard, more than one string istuned to the same note to provide extra loudness. For example, thenote at 1.10 x 102 Hz has two strings at this frequency. If one string slips from its normal tension of 6.00 x102 N to 5.40 x 102 N, what beatfrequency is heard when the hammer strikes the two stringssimultaneously?

What is the main difference between the formulas for kinetic energy (ke) and gravitational potential energy (pe)? a. ke depends on position and pe depends on motion. b. ke depends on motion and pe depends on position. c. both energies depend on motion, but only ke depends on position. d. both energies depend on position, but only pe depends on motion.
