● 0.3x10-4s
Time constant is L/R. Allow the original inductance of the coil be L0
and its original resistance be R0. The resistance and inductance of each
half is R=R0/2 and L=L0/2. Since they are connected in parallel, the
effective inductance is given by (L-1+L-1)-1=(L0/2)/2= L0/4. Similarly,
the effective resistance R=R0/4. Time constant=L/R=
(L0/4)/(R0/4)=L0/R0=1.8x10-4/6=0.3x10-4s. Answer: A uniformly
wound solenoid coil of self-inductance 1.8x10-4H and resistance 6Ω is
broken into two identical coils and connected in parallel across a 12V
battery of negligible resistance. What is the time constant for the current
in the circuit?
● Hurricanes turn clockwise in the Southern Hemisphere.
The Coriolis Effect is a natural angular momentum applied to large-scale
objects and is produced by the rotation of the Earth. The effect causes a
clockwise spin for air and water masses in the Southern Hemisphere,
and a counterclockwise spin for large objects in the Northern
,hemisphere. Answer: The Coriolis Effect causes what physical
phenomena?
● Anything that occupies space and has mass. Answer: Earth Science
deals with matter. Matter is often described as:
● the continents were once in very different positions than they are today
The fact that fossils of tropical plants have been found in Antarctica,
which is very cold and does not support tropical life, suggests that
Antarctica was at one time much closer to the equator and therefore in a
tropical climate. Answer: The fact that fossils of tropical plants have
been found in Antarctica is evidence of which of the following?
● a chemical reaction occurs
A chemical reaction is a change in a substance that transforms it into
other substances. A chemical reaction occurs when an apple is cut open
and turns brown. The reason the apple turns brown is when the apple is
cut open it reacts to the oxygen in the air. Answer: What happens when
an apple is cut open and then turns brown?
● Stem cells still retain the ability to differentiate.
,Stem cells are remarkable in that they still retain the ability to
differentiate into other types of cells. That is important for brain cell,
pancreatic cell, or any other type of cell in the body. In order to make the
repairs, raw materials (i.e. stem cells) are necessary. Answer: Why are
recent breakthroughs in stem cell research so important?
● osmosis
The more hypertonic the environment, the more water will diffuse out
because the salt concentration is greater outside the cell than it is inside,
causing the cell to shrink. If too much water flows out, the cell will die.
Freshwater organisms like the goldfish don't have extra salt in the cells
to slow down the process of osmosis like saltwater organisms do. So
putting a goldfish into a saltwater tank causes the goldfish's cells to
shrivel up and the goldfish would die from dehydration. Answer: A
goldfish is taken from a freshwater fish tank and put into a saltwater fish
tank and the fish dies shortly after. Which of the following terms
explains why the fish died?
● it is formed from minerals that have flat or needle-like crystals into
parallel layers.
Foliated metamorphic rocks are formed from minerals that have flat or
needle-like crystals into parallel layers. Slate is an example. Nonfoliated
rocks are composed of minerals with more block-shaped crystals.
Metamorphic rocks can melt and refreeze, but they wouldn't be foliated
if they had a haphazard pattern. Exfoliation is the process of peeling off
, rock layers, but the pieces don't form foliated rocks. Answer:
Metamorphic rocks are usually classified into two groups: foliated and
nonfoliated. Slate, shown above, is a foliated rock, which means:
● He expanded our notion about the age of the Earth.
James Hutton is best known for expanding our notion about the absolute
age of the Earth.
By observing geological formations, he found evidence supporting that
the Earth was much older than had been previously believed. Answer:
Your lesson plan requires you to prepare a report on James Hutton. What
is the basis of his fame?
● Autoimmunity
Stress, genetics, and age are all considered risk factors for disease.
Autoimmunity, when the immune system attacks the body, is considered
a mechanism of disease rather than a risk factor. Answer: Which of the
following is NOT a risk factor for disease?
● Genes located farther apart have a greater chance of a crossover
occurring
Recombination frequencies are related to the relative distance between
genes and can be used to map genes. Genes that are farther apart have a
