Step-by-step explanation:
given that V is directly proportional to u and inversely proportional to f , then the equation relating them is
V = ← k is the constant of proportion
(a)
to find k use the condition when u = 1 and f = 3 , V = , then
=
( cross- multiply )
6k = 3 ( divide both sides by 6 )
k = =
V = ← equation of proportion
(b)
when f = 4 and V = 1 =
, then
=
=
( cross- multiply )
4u = 40 ( divide both sides by 4 )
u = 10
