QUESTIONS WITH VERIFIED ANSWERS.
The Law of Reflectance: - correct answer-the angle of
incidence equals the angle of reflection. Scattering is merely a
reflection from a rough surface. Incoming light waves are
reflected at many different angles because the surface is
uneven.
The most commonly-seen type of lens is the _____ _____. A
convex lens is a converging lens; it focuses the light passing
through it to a point. A convex lens is used to bend light in a
magnifying glass so objects appear larger than they really are.
A concave lens spreads out light rays that have been refracted
through it. - correct answer-convex lens
A _____ lens is used to correct short-sightedness. - correct
answer-concave
Static electricity. - correct answer-In order to understand static
electricity, it is important to review the basics of atoms. An atom
consists of protons, electrons, and neutrons. Protons have a
positive charge, electrons are negatively charged, and neutrons
,have no charge. Because atoms normally have the same
number of electrons as protons, the positive and negative
charges cancel each other out and, as a result, atoms usually
have no charge; they are neutral. Static electricity is the result
of an imbalance between negative and positive charges in an
object. Normally, the protons and neutrons in the nucleus are
held together very tightly. But some of the outer electrons are
held very loosely; they can move from one atom to another. If
an electron is removed from a neutral atom, the atom is left with
more positive particles and acquires a positive charge. If an
electron is added to a neutral atom, the atom has more
negative particles and acquires a negative charge. The more
positive atoms or negative electrons you have, the stronger the
attraction for the other. For example, rubbing a shoe against a
carpet creates an excess of electrons. When reaching and
touching a doorknob a shock, or tiny spark, is felt or seen;
excess electrons are released to recreate a balance of
electrons and protons in atoms. Lightning is also a result of
static electricity.
Current electricity. - correct answer-Current electricity comes
from a stream of electrons moving through a conductor, such
as copper. Some materials allow charges, usually electrons, to
flow through the material. These materials are called
conductors, and the flow of charge is called current. Some
materials are better conductors than others; they offer very little
resistance to the flow of electrons. Most metals are very good
conductors—copper, silver, gold, aluminum, or steel, for
example. However, not all substances are good conductors.
Materials that do not conduct electricity well are called
,insulators. Rubber, plastic, wood, cloth, glass, and dry air are
good insulators; they have very high resistance to the flow of
electrons.
Materials that do not conduct electricity well are called_____. -
correct answer-insulators
In a circuit, electrons travel along a conductor in _____ loops. -
correct answer-closed
The word circuit means _____ - correct answer-circle
Magnetism - correct answer-A magnet is any object that has
the ability to attract ferrous objects like iron, steel, nickel, and
cobalt. Magnetite, called lodestone for many years, is a
naturally occurring iron ore that has this ability. Most permanent
magnets we use are manufactured and are a combination or
alloy of aluminum, nickel, cobalt, and iron, although none of
these metals is naturally magnetic. The magnetic field in a
permanent magnet is a result of electron spin. A magnetic field
is produced by spinning electrons in an atom. Every atom is
essentially a small magnet with a north pole and a south pole.
In nonmagnetic materials, electrons spin in random directions,
so the magnetic field is not noticeable. In magnets, however,
, the electrons all spin in the same direction—they are aligned—
and create a north pole and a south pole. When a bar magnet
is suspended at its center by a string, it will rotate until one end
points north. That end is called the north pole of the magnet
and the end that points south is called the south pole. In
magnets, unlike poles attract, and like poles repel. Either pole,
however, can attract iron objects such as pins and paper clips.
That is because under the influence of a nearby magnet, each
pin or paper clip becomes a temporary magnet, with its poles
arranged in a way appropriate to magnetic attraction.
_____, called lodestone for many years, is a naturally occurring
iron ore that has this ability. - correct answer-Magnetite
Surrounding all magnets is a region called the _____ _____. -
correct answer-magnetic field
Electricity and magnetism are closely _____. The movement of
electrons creates a magnetic field, so electric current creates a
magnetic field. This magnetic property can be used to make
powerful electromagnets. You can make an electromagnet by
simply coiling wire around a thin rod made of iron or steel (a
nail will work, too). When an electric current moves through the
wire, it makes a magnetic field. The strength of the magnetic
flow is dependent on the number of times the wire is coiled
around the rod, and the value of the current is dependent on
