Based on the equals method for Circle objects defined in Section 6.1, what is the output of the following code sequence?
Circle c1 = new Circle(5);
Circle c2 = new Circle(5);
Circle c3 = new Circle(15);
Circle c4 = null;
System. out. println(c1 == c1);
System. out. println(c1 == c2);
System. out. println(c1 == c3);
System. out. println(c1 == c4);
System. out. println(c1.equals(c1));
System. out. println(c1.equals(c2));
System. out. println(c1.equals(c3));
System. out. println(c1.equals(c4));

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.
