Determine the maximum bending stress developed in the steel if the beam is subjected to a moment of MM = 100 kN⋅mkN⋅m . Take EwEw = 10 GPaGPa , EstEst = 200 GPaGPa .

Agas expands from an initial volume of 0.040 m^3 and an initial pressure of 210 kpa to a final volume of 0.065 m^3 while its temperature is kept constant. how much work is done by the system?

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.

Ascientific blank must be testable and capable of being proven false?
