(3) replaced by a lower frequency tuning fork
(4) replaced by a higher frequency tuning fork

Vi. on another planet, a spring with constant 4.7 n/m is set up and allowed to expand verticaly freely. 8.4kg mass is placed on the spring and the spring extends 5.28m. calculate the exected extension on earth.
