A sample of 100 atoms of element “X” is collected. 29 atoms have a mass of 64 amu, 13 atoms have a mass of 70 amu and the remaining have a mass of 65 amu. Calculate the average atomic mass for element “X”. Then identify the element.

Atelevision set that has been running for a while heats up even the air around it. which two laws of thermodynamics could be used to analyze this scenario

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
