A:
Answer: (a) S = K/G (b) 4. 2 ( a decimal)Step-by-step explanation: From the statement , it meansS ∝ 1/GIntroducing the proportionality constant⇒ S = K/GGiven : S = 7 when G = 1.8Substitute the given values into the equationi.e 7 = K/ 1.8Which means K = 1.8 x 7 K = 12. 6Substitute the value of K into the equationi.e S = 12.6/ G(b) To find S when G =3 , you will need to substitute G = 3 into the equation i.e S = 12.6/ 3 S = 4.2
