Lucas puts new batteries in his radio-controlled car and its controller. He activates the controller, which sends a radio
signal to the car. The car moves forward. Name at least three
energy transformations that occurred.

Explanation:

When Lucas puts new batteries in the controller, the chemical energy of the battery would be converted to the electrical energy in a closed circuit. This will give the radio signal to the car to start its motor. When the motor will start, chemical energy would then be converted to mechanical energy. Finally, when the car will be running on the floor, the kinetic energy would be dissipated in the form of heat energy due to friction effect.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
