Answer:
g = 8
Explanation:
This is a question of inverse proportion
g varies inversely as √h
g ∝ 1/√h
Where ∝ = proportional symbol
g =k/√h
Where k is constant
When:
g= 4
h =100
4= k/√100
4= k/10
k = 4×10 = 40
Hence the relationship between g and h :
g= 40/√h
To find g when h = 25, we would insert the new value of h in their relationship
g = 40/√25
g = 40/5
g = 8
Hence when h decreases, g increases and vice-versa.
