g of objects A through D has the greatest total kinetic energy at the bottom of the ramp, or do all have the same kinetic energy? Which of objects through has the greatest total kinetic energy at the bottom of the ramp, or do all have the same kinetic energy? Object A has the greatest total kinetic energy at the bottom of the ramp. Object B has the greatest total kinetic energy at the bottom of the ramp. Object C has the greatest total kinetic energy at the bottom of the ramp. Object D has the greatest total kinetic energy at the bottom of the ramp. All objects have the same kinetic energy at the bottom of the ramp.

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
