What is an ellipse please help)
Answers
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

What did you discover about the polarity of rocks on the ocean floor near the Mid Atlantic Ridge? pls help its for an essay due soon
Answers
Explanation:
When lava gets erupted at the mid-ocean ridge axis it cools and turns into hard rock. As it cools it becomes permanently magnetized in the direction of the Earth’s magnetic field.Less than 60 years ago, scientists discovered that the Earth’s magnetic field has reversed its polarity (direction) hundreds of times during the past several hundred million years. A polarity reversal means that the magnetic North flips to where we know the South Pole is. At the mid-ocean ridge spreading axis, these flips in the direction of the Earth’s magnetic field are recorded in the magnetization of the lava. This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges.
These patterns of stripes provide the history of seafloor spreading. Geophysicists can read these patterns from the magnetic anomalies they measure with a magnetometer. Where the magnetic wiggles, or anomalies, are broader, the spreading rate has been faster. At slow spreading ridges, the anomalies are squeezed tighter together, but the basic patterns are quite similar so scientists can correlate or relate the magnetic wiggles to different parts of the global mid-ocean ridge.

If an object is placed in water and has a density of 1.9 g/ml will the object float or sink?
Answers
Answer:
float
Explanation:
since everything that have a density more than 1g/l (not g/ml) will sink and less than that will float
then 1.9g/ml < 1g/l
Answer:
it would sink
Explanation: it would sink because the density of water is 0.997 m/ml and 1.9 is more then that
when salt dissolves into water does it change its state
Answers
Answer:
no it doesn't change back
fine here When you dissolve salt in water, the sodium chloride dissociates in Na + ions and Cl - ions, which may be written as a chemical equation : NaCl (s) → Na + (aq) + Cl - (aq) Therefore, dissolving salt in water is a chemical change. The reactant (sodium chloride, or NaCl) is different from the products (sodium cation and chlorine anion).

Answers
A student predicts that a solution of ethanol (C2H5OH) and water will have a lower density at room temperature than that of pure water. By taking moisture the student can test this prediction.
What are the properties of ethanol ?Ethanol is a natural plant fermented by-product which can also be produced by the process of hydration of ethylene.
It is an important industrial reagent, can be used as a solvent, for the synthesis of solvent, organic chemicals and some additive to automotive gasoline.
Its chemical formula is C2H6O, two carbon atoms and one oxygen atom where as the structural formula is C2H5OH indicating that the two-carbon chain has a hydroxyl group.
Ethanol is always a liquid at room temperature and has the melting point of 156K and a boiling point of 351 K.
It is used in making many medicines like cough syrups, tonics, any proportion of ethanol is soluble in water.
Direct consumption of even a small quantity of pure ethanol is lethal to body.

Jane is a graphic designer who is hired by several different companies to create logos and marketing designs. As part of her final project, she makes sure to deliver images in several resolutions. Why is the resolution of an image important? Why would several different versions of the same image be needed? What would happen if a low-resolution image was used on a large poster? Explain your reasoning
Answers
Answer: I hope I can explain this well
the reason she makes copies of the image in different resolutions is because depending on the print size the lower resolution can look perfect for a small print and a higher resolution will look better on a large print, because larger prints are expanded, if you use a lower resolution image it will appear blurry on a large poster, the more pixels the better for a large poster
Explanation:
Answer:
Good Luck
Explanation:
Because larger prints are expanded, a lower resolution image will appear blurry on a large poster, so she makes copies of the image in various resolutions because, depending on the print size, a lower resolution can look perfect for a small print and a higher resolution will look better on a large print.

3. A recent flood in the area has caused many short-term changes to
the ecosystem. Which is a long-term change?
A. Standing water in the streets and sewers
B. Temporary displacement of organisms
C. Permanent change in the landscape
D. Poor water quality in rivers and streams
Answers
Answer:
c
Explanation:
While standing water in the streets and sewers (option A) and poor water quality in rivers and streams (option D) may persist for some time after the flood, they are generally considered short-term changes as they can eventually be remedied through clean-up efforts and restoration programs.
Temporary displacement of organisms (option B) can also be considered a short-term change, as organisms will eventually return to their original habitats once conditions improve.
However, a permanent change in the landscape (option C) such as altered river channels, new water bodies, or changes in topography, can have lasting effects on the ecosystem and its inhabitants. These changes may alter habitat suitability, nutrient cycling, and water availability, which can impact the ecosystem for years or even decades to come.
Answer: C
Explanation:
The landscape could be flooded. Houses and buildings may be restricted.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

How would you connect these items to make a circuit in order to power a light bulb? step by step explanation
-a light bulb
-2 batteries
-aluminum foil
-paper clips
-electric tape
Answers
Answer:
How would you connect these items to make a circuit in order to power a light bulb? step by step explanation
Making a Circuit:
1. Connect one end of each wire to the screws on the base of the light bulb holder. (If you’re using foil, ask an adult to help you unscrew each screw enough to fit a foil strip under it.)
2. Connect the free end of one wire to the negative (“-“) end of one battery. Does anything happen?
3. Attach the free end of the other wire to the positive (“+”) end of the battery. Now what happens?
Adding Power :
1. Disconnect the battery from your circuit. Stand one battery so that the “+” end is pointing up, then set the other battery next to it so that the flat “-” the end is pointing up. Tape around the middle of the batteries to hold them together.
2. Set a paperclip across the batteries so that it connects the “+” end of one to the “-” end of the other. Tape the paperclip in place with a narrow piece of tape (do not tape over the metal battery ends).
3. Turn the batteries over and tape one end of a paper clip onto each of the batteries. Now you can connect one wire to each paper clip. (The bottom of the battery pack should only have one paper clip – do not connect a wire to it.)
4. Connect the free ends of the wires to the light bulb.
(Note: Instead of steps 1-3, you can use two batteries in battery holders and connect them together with one wire.)

What physical property of mercury makes it best suited for use in a thermometer
Answers
Answer:
High coefficient of expansion
Explanation:
It is only mercury that is in liquid form at room temperature. It works on the principle of thermal expansion, it expands when heated and contracts when cooled. The very minute change can be notable by the use of mercury in the thermometer. So this property of the thermometer makes it suitable for measuring temperatures.
