Answer:
1/ K times
Explanation:
The capacitance of a parallel plate capacitor is given by
Where, A be the area of plates and d be the distance between the plates.
When a dielectric is inserted between the plates, the new capacitance is
The charge remains same.
As we know that
q = C V
The capacitance becomes KC so, to keep the charge remains same the potential difference should be 1 / K times.
V' = V / K
Answer:
E. A and B are equally good and better than C
Explanation:
This is the concept of trigonometry, the direction of the John will be given by:
tan theta=opposite/adjacent
suppose:
a=theta
opposite=4 mph
adjacent=5.5 mph
tan a=4/5.5
a=tan^-1(4/5.5)
a=36
therefore the boat canoe will be moving 36 degrees from East, his direction will be 126 degrees south east
The order of the location of each process in the carbon cycle are as follows;
- <u>Ingestion → Decomposition → Fossilization → Combustion </u>
Reasons:
Ingestion; During the ingestion process, the products of the direct Sunlight and photosynthesis, which
are energy rich chemical substances are ingested by herbivores.
Decomposition; The plants and animals die and undergo decomposition.
Fossilization; A long period the decomposed plants and animals manifest
into hard petrified materials, with their parts transformed to fossils.
Combustion; The remains of plants and animals, subjected to heat and
pressure due to compression, as when as bacteria decomposition that
removes several other elements, leaving a carbon and hydrogen rich
sludge that can be processed into fuel used for combustion. The
combustion process produces carbon dioxide which restarts the cycle.

The amount of energy needed to increase the temperature of a substance by
is given by:
where
m is the mass of the substance
is the specific heat capacity of the substance
is the increase of temperature
In our problem,
, while
and the specific heat capacity of iron is
if we plug these numbers in the equation, we find the amount of energy needed:
