3.5x10^7 J of heat transfers into an engine. If 2.1x10^7 J of work is performed what is the efficiency of the engine? How much heat is lost to the environment?
600 J of work is done on a system in a process that decreases the thermal energy of the system by 300 J .
How much heat energy is transferred to or from the system as heat? Enter positive value if the energy is transferred to the system and negative if the energy is transferred from the system.
Express your answer in joules.
A PHYS 1510 student was working on a robotics project. The joints on the machine they were building were powered
by pistons.
Based on how hot the machine was getting, the student was able to figure out that 2.34 J of thermal energy was
produced by every piston every time the piston was fully extended to 0.4064 m.
What was the force of friction that the piston experienced during every extension?
Assume friction is the only source of thermal energy. Include units in Sl.
