1. Find the flow of the velocity field F = (y + z)i + xj - yk, where velocity is measured in meters per second, over the curve r(t) = e¹i - e²lj + e^-1k, 0 ≤ t ≤ In 2. 

2. Salt water with a density of ∂ = 0.25 g/cm² flows over the curve r(t) =√ ti + tj, 0  ≤ t ≤ 4, according to the vector held F = ∂v, where y = xyi + (y - x) is a velocity field measured in centimeters per second. Find the flow of F over the curve r(t)
