Spark Your Learning Two submersibles, Atlas and Pisces, are exploring an ocean trench.
Every hour, Atlas makes 5 descents of 10 meters each. Every hour,
Pisces makes 2 descents of 50 meters each. What integer represents
the total change in elevation for each submersible after 3 hours?

Find a parametrization for the curve「and determine the work done on a particle moving along γ in r3 through the force field f: r^3--r^3'where f(x,y,z) = (1,-x,z) and (a) im (γ) is the line segment from (0,0,0) to (1,2,1) (b) im (γ) is the polygonal curve with successive vertices (1,0,0), (0,1,1), and (2,2,2) (c) im (γ) is the unit circle in the plane z = 1 with center (0,0,1) beginning and ending at (1,0,1), and starting towards (0,1,1)
