Which of the following best explains the energy transfer in this system?
Battery
Chemical energy in the battery is converted into electrical energy, which is then converted into sound and heat energy
O Chemical energy in the battery is converted into electrical energy, which is then converted into light and nuclear energy.
Electrical energy in the battery is converted into electrical energy in the docking station, which is then converted into sound, heat, and light
energy
Electrical energy and chemical energy in the battery is converted to sound and heat energy

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
