T1= 400K
T2= 300k, T3= 200K
The circle represents a reversible engine. During some integral number of
complete cycles the engine absorbs 1200 J from the reservoir at 400 K and performs 200 J
of mechanical work. (a) Find the quantities of heat exchanged with the other reservoirs,
and state whether the reservoir gives up or absorbs heat. (b) Find the change in entropy
of each reservoir, (c) What is the change in entropy of the universe ?

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.
