The correct answer is
c) Neither person is correct because light does not change frequency when it travels through different media
In fact, light changes both wavelength and speed when it travels through different media, but the frequency remains the same.
No. Potentional (other wordy here) are a few of though.
A pure substance because it cannot be separated into parts
From our studies of the work of Professor Newton,
we have learned that
F = M a .
That is, the product of an object's mass and its acceleration
is equal to the net force acting on it.
An object in equilibrium is an object that has no acceleration.
In other words, it may be moving in a straight line at a speed
that does not change, or it may be just lying there before us.
In either case, since the object has no acceleration, we glance
at Newton's formula, and we instantly realize that the net force
on the object must be ZERO.
The object behaves just as if there were NO forces acting on it at all.
Answer:
Copper is a better heat conductor than glass. In general, we think of metals as good conductors. In fact, metals vary widely in their conductivity but, overall, they are better conductors of heat than most liquids and gasses. Other solids also vary in their capability to conduct heat.
