A boy releases his balloon, which slowly rises into the sky. if the balloon has a diameter of 20.0 cm when the child releases it, what is its diameter at a height of a) 1,000 m, b) 2,000 m, and c) at 5,000 m? assume that the balloon is very flexible and that you can neglect the surface tension

b

step-by-step explanation: a third of 24 is 8, 8 times 3 is 24 so 8 - 2 would be 6

d) physical means can be used to separate the components of air.

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
