<span>A method of processing coal to remove contaminants by mixing coal in a solution of potassium permanganate in a selected concentration range, rinsing the coal, mixing the coal in a solution of ammonia hydroxide in a selected concentration range to cause the solution to be brought into contact with the surfaces and pores of the coal, discharging the processed coal from the second reaction vessel, monitoring the process to detect when the concentration of aqueous ammonia in the second reaction vessel has fallen below the selected range, and feeding aqueous ammonia solution with an ammonia concentration in or above the selected range to the second reaction vessel to return the solution to within the selected range.</span>
Answer:
Compression squeezes rocks together, causing rocks to fold or fracture (break) (figure 1). ... Rocks under tension lengthen or break apart. Tension is the major type of stress at divergent plate boundaries. When forces are parallel but moving in opposite directions, the stress is called shear
Explanation:
Your question could mean one of two different things.
You could be asking "How do I figure out the longitude and latitude
of, let's say, Killeen, Texas."
The answer to that is: You look on a map or a globe that has latitude
and longitude lines printed on it, find Killeen, Texas, and estimate its
coordinates as well as you can from the lines printed nearest to it.
Or you could be asking "If I'm out in the middle of the ocean at night,
how do I figure out the longitude and latitude of where I am ?"
I'm afraid the answer to that is far too complicated to write here.
All I can say is: The science of "Navigation" was developed over a period
of hundreds of years. If you look at the history of sea exploration through
the centuries, you see how the explorers ventured farther and farther from
their home ports as time went on. The reason for that is that they were
developing better and better methods of figuring out where they were as
they sailed.
And about 20 years ago, that all changed. Drastically. Now, anybody at all
can walk into his neighborhood sporting-goods store, and buy a little device
that fits in his shirt pocket or in the palm of his hand, and whenever he has a
view of the sky, it can give him the latitude and longitude of the place where
he's standing, more accurately than the best navigators in the US Navy or
the British Armada could ever calculate it before.
That was when countries started putting up bunches of little satellites
to broadcast signals to our pocket receivers.
The satellites that the US put up are called the Global Positioning System . . .
the GPS.

Explanation:
smelling is not a physical change we can see that melting and cutting are physical changes
If the earth’s tilt on its axis were to increase by 20 degrees, the tropic of Capricorn will be at 23.4° + 20°= 43.4°
If the inclination of the axis of the Earth were to rise, the following changes would occur: In various parts of the planet, both the length of the days and the length of the nights would lengthen or shorten, respectively. The duration of each season as well as its average temperature would be altered. There would be different temperatures in different parts of the planet.
The present angle of the Earth's axis of rotation is 23.5 degrees. Earth's seasons are the result of the planet's axis being tilted. The amount of direct sunlight reaching various latitudes and longitudes on Earth varies throughout the year. When the North Pole is in its most equatorial position, it experiences summer, whereas the South Pole is at its most southern position and so experiences winter. When the South Pole is leaning toward the sun, the situation is reversed.
Some people wrongly believe that summer is when Earth is closest to the Sun, but that is not the case. However, in winter the Northern Hemisphere is physically closer to the Sun than it is in summer. Because of how far away Earth is from the Sun, the planet experiences very small temperature swings when the Sun moves closer or further away.
The Earth's axis of rotation is skewed because of a collision with a massive extraterrestrial object named Theia. The impact jarred the axis out of whack and set in motion the release of material that eventually coalesced as the moon of Earth. Various portions of Earth get direct sunlight at different times because of the tilt's consistent orientation with respect to the Sun.
