An experimental device imparts a force of magnitude f = 40 lb to the front edge of the rim at a to simulate the effect of a slam dunk. compute the moment of the force f about point o and about point b. the moments are positive if counterclockwise, negative if clockwise. finally, locate a point c from the base at o to the location on the ground where the force imparts zero moment. the distance d from point o to point c is positive if c is to the right of o, and negative if to the left.

1) sections 1, 2, and 10 are significant primarily because they suggest the likelihood that a) widow wycherly is actually the woman in the full-length portrait. b) dr. heidegger wants to include his guests in an experiment with the water. c) dr. heidegger plans to drink some of the water from the vase and needs witnesses. d) the guests will be asked to witness dr. heidegger's transformation when he drinks the water.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
