Two plastic plates are glued together across a seam labeled a-a. The cross-section
of the plate where the load p is applied is 40 × 70 mm and is uniform throughout. The
maximum allowable tensile stress on the glue joint is 200 kPa and the allowable shear stress is
300 kPa. What is the maximum load that can be applied to the bar, P?

Tungsten-filament lightbulb emits light based on the temperature of the filament. which phenomenon does this demonstrate?

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u.s. legal proceeding.)

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.
