- Conclusions The Stefan-Boltzmann Lawarrow_forwardA man of weight 600 N is standing on the top of a building of height 10 m, the energy possessed by the man is Select one: O 6000 Nm O 60 Nm O 58800 Nmarrow_forwardThe shaft is supported by a smooth thrust bearing at A and a smooth journal bearing at B. (Figure 1) -0.8 m 600 N-m -0.8 m -0.8 m 900 N Draw the shear diagram for the shaft. Draw the moment diagram for the shaft.arrow_forward
- True. O Q2. The conservation of energy principle states that; during interaction energy can transform from one form to another and the total amount of energy does not remain .constant True. O False. O محو النموذج التالي عدم ارسال كلمات المرور عبر نماذج Go ogle مطلقا.arrow_forwardA cylinder which is in a horizontal position contains an unknown noble gas at 42100 Pa and is sealed with a massless piston. The piston is slowly, isobarically moved inward 0.189 m, while 15900 J of heat is removed from the gas. If the piston has a radius of 0.327 m, calculate the change in internal energy AU of the system. AU = Jarrow_forwardOn a molecular level, heat can be thought of as representing changes in the positions of the energy levels of a system. True Falsearrow_forward
- The Cyclic integral of a property is always zero. Select one: O True O Falsearrow_forwardAn open system has a mass transfer across its boundaries, and the mass within the system is not necessarily constant is a region of constant mass and only energy is allowed to cross the boundaries O cannot transfer either energy or mass to or from the surroundings O none of the abovearrow_forwardIce is added to hot tea in a thermos and then, the thermos is closed. The energy loses through the thermos lid and walls are negligible. When the system including ice and water reached thermal equilibrium, the energy of ice increased by 10 J. How did the energy of water change? O Unknown O Did not change O Increased by 10J O Reduced by 10Jarrow_forward
- answer please varrow_forwardThe volume and temperature of a gas at the beginning of expansion are 0.0056m3 and 183°C, respectively; at the end of expansion the values are 0.0238 m3 and 22°C, respectively. Assuming expansion follows the law PV^n=C, find the value of n.arrow_forwardThe 1st law of thermodynamics is ΔU = Q –W. Use this statement of the 1st law to show (mathematically) its equivalent statement: “Total energy of the universe is constant”. Here, the universe can be defined as: system + surroundings (everything but the system –everything outside the system). (Hint: this can be shown by two ways-you may either treat system and surroundings as two systems next to each other, or you may treat system + surroundings (universe) as one system.)arrow_forward
