Aparticle moves along line segments from the origin to the points (1,0,0), (1,5,1), (0,5,1), and back to the origin under the influence of the force field below. find the work done. f(x, y,z) = z^2 i + 2xy j + 2y^2 k.

Apulley with a mechanical advantage of 5 will require you to pull times the amount of rope. a. 1/5 b. 5 c. 10 d. 15

An incident ray through the focal point of a spherical mirror will: reflect through the center of curvature. reflect back through the focal point. reflect parallel to the principle axis. reflect the same direction as the incident ray.
