Problem 28P

What mass of steam at 100°C must be added to 1.00 kg of ice at 0°C to yield liquid water at 20°C?

SolutionConsider the pendulum has some small angle oscillation,in this case pendulum undergosimple harmonic motion.the time periods of the pendulum on the moon and on the earth are T earth= 2L /g earth and T mars= 2L /g marsDividing the equations T /Tmars= g /g earth mars earth g mars= gearthT earthTmars) 2 2 =(9.8 m/s )(1.50 s/2.45 s) 2 =3.67 m/sBecause of T > T ,same length pendulum will give smaller value of g on Mars. earth mars
