If humans were the third level consumer, would there have been enough food from this ocean ecosystem for them to have a meal in each trial?

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

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
