There is a free body diagram drawn on a block on a 50-degree incline with 3 force vectors. The first vector is pointing away from the surface of the incline and perpendicular to the surface, labeled F Subscript N Baseline. The second vector is pointing into and perpendicular to the surface of the incline, labeled F Subscript g y Baseline. The third vector is pointing straight down to the center of the earth, labeled F Subscript g Baseline. There is another force parallel to the surface of the incline and down the hill starting at the tip of the F Subscript g y Baseline vector, labeled F Subscript g x Baseline. A box with a mass of 100.0 kg slides down a ramp with a 50 degree angle. What is the weight of the box? N What is the value of the normal force? Round the answer to the nearest whole number. N What is the acceleration of the box? (Disregard friction and air resistance.) Round the answer to the nearest tenth. m/s2

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.
