3. What conclusion would you draw if a seismogram from a particular seismic station showed only P waves?4. Why is it better to use data from three or more seismic stations to find the epicenter of an earthquake?
Answers
3. The Earthquake occured on the other side of the Earth
Explanation:
One of the main difference between P-waves and S-waves is that P-waves can travel through solids and liquids, while S-waves can only travel through solids. They are not able to travel through liquids.
So, if a seismic station showed only P waves, it means that there was some area in liquid state between the seismic station and the hypocenter of the earthquake. Inside the Earth, the outer part of the core is made of liquid, so this means that there outer core was along the line connecting the seismic station and the hypocenter and "blocked" the S-waves: therefore, the earthquake occurs on the other side of the Earth.
4. In order to determine with precision the location of the epicenter
Explanation:
One seismic station is only able to determine the distance of the epicenter - so, by using one seismic station only, we are only able to tell that the epicenter is located on a point along a circle, centered around the seismic station.
If we use two seismic station located at different points, we can draw two circles of possible locations for the epicenter, one for each seismic station. The intersection between the two circles will give us the exact location of the epicenter. However, two circles have two intersections: therefore, there is still an ambiguity concerning the exact location of the epicenter.
If we use three stations, therefore, we can draw three circles, and they have one intersection only: this intersection will give us the exact location of the epicenter.
Answer:
1. P waves can travel through liquid and solids and gases, while S waves only travel through solids. Scientists use this information to help them determine the structure of Earth. For example, if an earthquake occurs on one side of Earth, seismometers around the globe can measure the resulting S and P waves.
2. P waves can travel through liquid and solids and gases, while S waves only travel through solids. Scientists use this information to help them determine the structure of Earth. For example, if an earthquake occurs on one side of Earth, seismometers around the globe can measure the resulting S and P waves.
3. If a seismogram records P-waves and surface waves but not S-waves, the seismograph was on the other side of the Earth from the earthquake because those waves cannot travel through the liquid core of the earth.
4. Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Knowing this helps them calculate the distance from the epicenter to each seismograph.
5. As the P and S waves travel out from an earthquake the P waves get progressively farther ahead of the S waves. Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave.

the bell, the balloon
contracted
expanded
Answers
When the pump removed the air in the bell, the balloon expanded.
Option: B
Explanation:
In order to construct our own environment in the glass jar known as bell jar system, which can be used to explore and consider our larger environment on Earths, for an instance. Here a glass jar that hinges on an airtight rubber basis i.e seals appropriately. At the top of the jar, a bung is connected to it which passed via a metal tube. It has an adjacent flexible tube that goes to a hand vacuum pump and the best hand-powered pump was made with a wine preserver.
When the pump extracts the air from the bell jar, the pressure inside the balloon naturally decreases. The balloon usually has a air pressure around it, which restricts its size, but when this air is extracted and the pressure around it decreases the gas in the balloon will expand and the balloon seems to be inflating. When you release the air back into the bell jar, it will once again compress back to its actual size.
Speed is constant.
Speed has direction and velocity.
Speed is measured over time.
Answers
The statement about speed and/or velocity which is true is: Velocity has both speed and direction.
Velocity refers to the rate of change in displacement (distance) with time. Velocity is a vector quantity and this simply means that, it has both magnitude (speed) and direction.
Mathematically, velocity is given by the formula;
On a related note, speed is a scalar quantity because it has magnitude but no direction.
However, both speed and velocity are measured in meters per seconds.
In conclusion, the relationship between speed and velocity is that velocity has both speed and direction.

Ah hah ! I work with these things all the time, so I can read it straight
off the picture. However, I realize that you probably don't, and can't ...
otherwise you wouldn't need to look for help online. So I'll try to
explain through it:
-- This is a "topographic map", and those brown lines on it are
"elevation contours".
-- All of the points on one brown line are all at the same elevation
(altitude, height, etc.), so if you follow one of the brown lines wherever
it goes, you're following a level path.
-- The little numbers somewhere on each brown line tell you the elevation
(above something) of all the points on that line. You can see lines that
are 35-ft, 45-ft, 50-ft etc. above whatever the reference is for this map.
If a line has no numbers on it, then it's halfway between the next lower
line and the next higher line. There's a line on this map with no number
on it between 35 and 45 ... the elevation of every point on this line is 40.
There's another one between 45 and 50 with no number on it ... every
point on that line must be at elevation of 47.5 .
-- On this kind of map ...
==> The flattest ground is where the lines are far apart, like where
that lake is. That's where there's a big distance between the 25-ft
line on one side, to the 30-ft line on the other side. All of the land
between those 2 lines is within 5 feet of the same height.
Same for the land between the 30-ft line and the 35-ft line ... every
point between those 2 lines is within 5 feet of the same height. It's
a very level place.
The gentlest 'shallowest' slope is always on the path that crosses the
fewest lines, or where the lines you have to cross are the farthest apart.
That's how we'll find the answer to the question, in just a moment.
==> The steepest slope is where the lines are close together, like
from 35-ft to 45-ft to 50-ft. In that short distance, the land rises 15-ft
because it's going up the steep side of Mount Cleveland.
==> You can also see where the peaks are, like where the 52-ft line
makes a circle. The peak of the mountain is inside that circle, and from
there, no matter which way you walk from the peak, the land goes down.
-- The absolutely shallowest path to the peak of the mountain would start
on the left side of the map, about 1/3 of the way up from the bottom.
There seems to be 2 lines there, but if you follow them up and around,
you find that they're both the same 50-ft line. So from that point on the
edge, all the way to the peak of the mountain, the land only rises a
little more than 2 feet. But you'd still have to get yourself up to that
starting point, and this path is not one of the choices.
-- If you start at the bottom center just below the end of the lake, OR
if you start from the lower right in Arthur Park, OR if you start at the
upper right in the marsh and swamp up at that end of lake, heading
for the peak of the mountain from any one of those points, you start
from elevation lower than 30 feet, and your hike is flat and pretty level
for a while, until it gets to the 35-ft line. And then, suddenly, it goes
ZUP ... 17 feet straight up to the top, in a short distance from there,
and crossing lines that are close together.
-- If you start from the bottom left corner, that point is already at an
elevation of about 45-ft, so it only has about 7-ft more to rise from there
to the peak. ALSO ... Starting from there, and going all the way to the
peak, the path goes roughly the same way the brown lines go ... it's
roughly parallel to them ... so there's more distance from one line to
the next one.
So "bottom left" is the place to start.
Note:
The numbers on the lines of a real topographic map are much more
likely to be marked in meters, not feet, so everything I've just described
would be 3.28 times as hard to climb.
