Object A is stationary while objects B and C are in motion. Forces from object A do 11 J of work on object B and -5 J of work on object C. Forces from the environment do 4 J of work on object B and 8 J of work on object C. Objects B and C do not interact.

What is ?Ktot if objects A, B, and C are defined as separate systems?

What is ?Uint if objects A, B, and C are defined as separate systems?

What is ?Ktot if one system is defined to include objects A, B, and C and their interactions?

What is ?Uint if one system is defined to include objects A, B, and C and their interactions?

As an object moves from point A to point B only two forces act on it: one force is nonconservative and does –40 J of work, the other force is conservative and does +60 J of work. Between A and B, Select one: the potential energy of object increases, mechanical energy decreases. the potential energy of object decreases, mechanical energy increases. the potential energy of object increases, mechanical energy increases the potential energy of object decreases, mechanical energy decreases.

Three objects (A, B, and C) are originally far apart. Object B is brought into contact with object A, and no heat flows from one object to the other. Then, object B is moved away from object A and brought into contact with object C. When object B touches object C, the temperature of the two objects changes. Objects B and C eventually reach thermal equilibrium. (a) Give as much information as you can about the original temperatures of the...

I ONLY NEED PART B ANSWERED. EVERYTHING ELSE IS LISTED FOR INFO PURPOSES A. An object of mass m1 = 17 kg and velocity v1 = 6.5 m/s crashes into another object of mass m2 = 5 kg and velocity v2 = −14.5 m/s. The two particles stick together as a result of the collision. Because no external forces are acting, the collision does not change the total momentum of the system of two particles, so the principle of conservation...

Specific Heat The heat capacity of an object indicates how much energy that object can absorb for a given increase in that object's temperature. In a system in which two objects of different temperatures come into contact with one another, the warmer object will cool and the cooler object will warm up until the system is at a single equilibrium temperature. Note the difference between the terms molar heat capacity, which has units of J/(mol⋅∘C), andspecific heat, which has units...
