which wave will produce the highest pitch?

wave 1

wave 2

wave 3

wave 4

wave 4 is the right answer of following number

Wave 4

im taking the quiz right now

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
