White light is shining on a green grape. The grape _____.
Marat540 [252]
The grape absorbs all colors except green, and green light is the

Classifying Matter
Schach [20]

Answer:

Solid, liquid, Gas

Explanation:

There are three main states of matter:

- Solid: a substance in a solid state has a definite shape and volume. When in solid state, the particles of the substance are tightly bound together, so they cannot move freely, but they can only vibrate about their fixed position. An example of this state is ice

- Liquid: a substance in a liquid state has definite volume but no definite shape. When in liquid state, the particles of the substance are not tightly bound, so they can slide past each other; however, there are still intermolecular forces that keep the particles close to each other, so that they cannot move freely. An example of this state is liquid water

- Gas: a substance in a gas state has no definite shape or volume. When in gas state, the intermolecular forces between the particles are negligible, so the particles are completely free to move far away from each other. An example of this state is steam

Describe an electromagnet and how it is used
Illusion [34]

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of insulated wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.

The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.

Electromagnets are widely used as components of other electrical devices, such as motors, generators, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment. Electromagnets are also employed in industry for picking up and moving heavy iron objects such as scrap iron and steel.<span>[2]</span>
