Question
In a closed system, what forms of energy transfer can take place? Lifting a weight to height of 20 m takes 30 seconds for 1 crane but 10 seconds for another crane. Is there any difference in the amount of work done on the weight by each crane. For full credit, you must explain your answer. The torque applied to a shaft can be expressed with the units N*m. This dimension is equivalent to Power Energy Force Pressure When a closed system that contains one component undergoes a process between two specified states, the change in temperature between the end states depends on the details of the path. Circle one answer below and briefly explain. True False More information is needed If the external absolute pressure is 1 atm and the absolute pressure of a refrigerant in a cycle is 0.8 atm, the gage pressure of the refrigerant is 0.2 atm. Circle one answer below and briefly explain. True False More information is neededExplanation / Answer
1.“energy” or as “work" 2.Yes there is difference in work done because the time taken is different the acceleration is also different so Force is acting in each case is different so as the Work 3.(b)Energy because Energy is work done and Torque is force *distance 4.a)true 5.a)true
