(a) what is the length of a simple pendulum that oscillates with a period of 3.2 s on earth, where the acceleration due to gravity is 9.80 m/s2, and on mars, where the acceleration due to gravity is 3.70 m/s2?

length (earth)=?

length (mars)=?

(b) what mass would you need to suspend from a spring with a force constant of 20 n/m in order for the mass-spring system to oscillate with a period of 3.2 s on earth, where the acceleration due to gravity is 9.80 m/s2, and on mars, where the acceleration due to gravity is 3.70 m/s2?

mass (earth)=?

mass (mars)=?
