-- If the field were inclined to the surface, then it would have
some component parallel to the surface.
-- Then, since we're talking about a conductor, the charges
on the object would move in response to that component
of the field, until there was no longer any component of the
field trying to move them.
Answer:
The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy.
i hope this helps.
Explanation:
Answer:
and
. The missing ion would be
.
Explanation:
In a double replacement reaction, two ionic compounds exchange their ions to produce two different ionic compounds.
In this question, the two ionic compounds are:
, and
.
In particular,
is made up of
ions and
ions, while
is made up of
ions and
ions.
In a binary ionic compound, cations (positive ions) can only bond to anions (negative ions.)
is a cation. In
,
was bounded
anions. During the reaction, it bonds with
anions to produce
.
is also a cation. In
,
was bounded to
ions. During the reaction, it bonds with
anions to produce
.
Hence, the two products will be
and
.
Note that charges on the ions must balance. For example, a
ion carries twice as much charge as an
ion. As a result, each
ion would bond with twice as many
ions as
would in
.
