heat will flow from object a to object b if:

1 the molecular average kinetic energy of the two objects is the same.

2 the molecular average kinetic energy of a is higher than that of b.

3 the molecular average kinetic energy of b is higher than that of a.

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.

In a heat engine if 1000 j of heat enters the system and the piston does 500j of work, what is the final internal energy of the system if the inital energy was 2000 j1.write the equation2.list out your known variables 3. plug the numbers into the equations4.solve 5.write your solution statement that includes initial energy and final energy added.

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?
