Hi please help me answer these questions for Physics. Please include the explanation.

l} A34wkg child on an \"IE-kg swing set swings back and forth through small angles. If the length of the VEI'Y light supporting cables for the swing is 3.3- 111... how long does it take for each complete backandforth swing? Asslu'ne that the child and swing set are very small compared to the length of the cables. A] 3.6 s 1204.0 s (:14: s o} 4.3 s 2] A simple pendulum has a period T on Earth.
