Explanation / Answer

Given :       Period of the pendulum ( T ) =2.94 s        Accleration ( g ) = 9.8m/s2       Legth ( L ) = ?     As we know that      For samll amplitudes  Period T = 2 L/g        L = Tg / 2      L = ( T g / 2)2           Solvefor L = ------ m   b ) Legth ( L ) = 0.676 m acceleration due to gravity on moon ( g )= 1.63 m/s2 Period ( T ) = ? Period T = 2 L/g                 = ------ s    c )        mass ( m ) = 0.311kg       Spring constant ( k ) = 43.5N/m        Dispalcement ( x ) = 6.78cm = 6.78 * 10-2 m        Frequency ( f ) =1/2 k/m                               = ------ Hz     Plugin the values and solve it Period ( T ) = ? Period T = 2 L/g                 = ------ s    c )        mass ( m ) = 0.311kg       Spring constant ( k ) = 43.5N/m        Dispalcement ( x ) = 6.78cm = 6.78 * 10-2 m        Frequency ( f ) =1/2 k/m                               = ------ Hz     Plugin the values and solve it
