Most likely solid. Molecules move in a chaotic matter, which a Scottish botanist found out in the 19th century. In gases, this chaotic movement is the most “dramatic” and they move around freely; in liquids it’s a bit less noticeable, and in solids the particles oscillate around locked positions. Movement in plasma is similar to gas.
Answer:
The sun touches earth during daytime and the suns rays heat our earth giving us heat. The sun heating the earth is also considered radiation.
Explanation:
Newtons first law is that an Object that is in motion will stay in motion until an unbalanced force acts upon it, and part 2 is that an object at rest will stay at rest until and unbalanced force acts upon it
As a transformer generates ac current of different voltage when the switch is closed and the current flows in the primary coil which induces a magnetic field.
Answer: Option 2
<u>Explanation:</u>
A transformer is an electric device which can vary the potential differences or voltages of an alternating current. It's a simple device composed of an iron core, a primary and the secondary current conducting coil.
The primary coil is attached to the switch which provides ac current through potential difference. Now this current induces a magnetic field in the iron core. When the voltage of this ac current is varied, the magnetic field varies and starts inducing ac current of different voltage in the secondary coil.
Thus, an AC current of different voltage flows in the secondary coil that can be used in small electric devices. This is how a transformer works. There are two kinds of transformers- Step Up and Step Down. A step up transformer increases the potential difference whereas the step down does the opposite.
Answer:
Liquid
Explanation: It can't be gas because gases are all around us and we can still see light. For solids it can't even move through a solid. Ex: If you're in a solid dome made of rock you can't get any light through. Let me know if I'm right!
