Free energy of a 2-state system physics. take the two states to have energies 0 and e a) find the free energy as a function of temperature b) from the free energy determine the energy and entropy. (c) determine the heat capacity (also known as the specific heat) at constant volume and sketch it as a function of temperature.

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

a=d/t

a="triangle"v/t

explanation:

a = acceleration

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
