Given that T =2 pz,find the value of T√7² + g²if I = 3.142,1 = 7.8

1.	Given that T =2 pz,find the value of T√7² + g²if I = 3.142,1 = 7.89 and g = 9.81.(Give your answer correct to 3 significant figures.) [(A) 3.94(B) 394(C) 39.4(D)4.39
Answer» Step-by-step EXPLANATION: Solution T = 2 π l √ l 2 + g 2 π = 3.142 l = 7.89 g = 9.81 T = 2 × 3.142 × 7.89 √ ( 7.89 ) 2 + ( 9.81 ) 2 = 49.5492 √ 158.4882 = 49.5492 12.589 = 3.935 = 3.94
