Answer:
v = k[tex]\sqrt{E}[/tex]
Step-by-step explanation:
Given v is proportional to [tex]\sqrt{E}[/tex] then the equation relating them is
v = k[tex]\sqrt{E}[/tex] ← k is the constant of proportion
v = k√E
v is proportional to square root of E means:
v ϱ √E
the general formula for variation is y=kx
as y is proportional to x
