What is an ellipse please help)
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.
Maybe they might use that math thing for Science.

Answer:
Yes
Explanation:
Water being burnt in a pot of fire results in H20 Gas.
Answer:When you boil water, the heat given off is a sign that chemical bonds are being broken and new ones are being fore broken.
Explanation: false Water boiling is a physical change and not a chemical change, therefore no bonds are broken.

Terrence measures the amount of water displaced by various objects when they are dropped into a graduated cylinder of water. By looking at his data, he realizes that the amount of water displaced depends on either the mass or the volume of the object, depending on whether the object sinks or floats.
Which data table includes all the information Terrence needs to come to this conclusion?
Answer:
Y
Explanation:
Logic
Photosynthesis begins when chlorophyll molecules in the plant absorb light energy from the sun. Along with sunlight, CARBON DIOXIDE (CO2)/OXYGEN (O2) and HYDROGEN (H)/WATER (H2O) are also taken in by the plant. Light energy from the sun FUSES/SPLITS water molecules (H2O) into hydrogen (H) atoms and oxygen (O) atoms. Pairs of oxygen atoms combine to form oxygen gas (O2). The oxygen gas (O2) leaves the plant as a WASTE/SUGAR product. The carbon dioxide (CO2) and hydrogen (H) molecules are made into WASTE/SUGARS, which are used by the plant to make energy. Also during this process, light energy from the sun transforms into THERMAL/CHEMICAL energy that is stored in sugars.

7: How many times can a volcano erupt?
Answer:
Some small volcanoes only erupt once in their lives,
while other volcanoes erupt multiple times. Kilaeua volcano in Hawaii, which has been erupting continuously since 1983, is the world's most active volcano. While some volcanoes erupt at regular intervals, there are always exceptions to the rule
Answer:
small volcano's only 1 time while big volcano's mutiple times
Explanation:
What makes the atomic radius change down a column of the periodic table?
O A. The greater number of total electrons, the larger the atomic radius.
O B. The more valence electrons listed, the larger the atomic radius.
C. The more sublevels occupied, the larger the atomic radius.
O D. The larger the highest energy level number, the larger the atomic
radius.
Answer:
As you go across a period, radius shrinks because you are adding protons. The added positive charge increases pull on the electron shells. So I believe the answer is D
The statement, that describes the atomic radius change down a column of the periodic table is "the larger the highest energy level number, the larger the atomic radius."
What is atomic radius?The size of an atom is described by its atomic radius. Atomic radius is commonly defined as the total distance from an atom's nucleus to the electron's outermost orbital.
The atomic radii of elements steadily grow from top to bottom in a group. As we move down the group, the atomic number rises, and so does the number of shells. Furthermore, as we advance down the group, the valence electrons are present in a higher shell, increasing the distance of the valence electrons from the nucleus. As a result, the attraction between the nucleus and the valence electron weakens. When a result, as one moves along a group, the atomic radius grows.
As the number of energy levels (n) decreases down a group, the distance between the nucleus and the outermost orbital rises. As a result, the atomic radius increases.
Hence, the correct option is D.

Observations 1: sunny and warm
2: cloudy and rainy
3: drop in temperature
4: clear skies and cold temperatures
A student tracks the daily weather. The student’s observations are logged in the table. Which factor in the atmosphere best explains the student’s observations?
A cold front moved into the area.
A warm front moved into the area.
High levels of moisture are contained within an air mass.
A warm air mass replaced a cold air mass.
The factor that explains the observations is that the high levels of moisture are contained within an air mass. So the correct option is C.
What is an air mass?An air mass is a sizable portion of the atmosphere that has a largely constant temperature and moisture content. Air masses may travel thousands of kilometers over the surface of the Earth and can extend up to 16 km (10 mi) into the atmosphere, or the stratosphere.
Large uniformly cooled and humid surfaces are known as source zones where air masses develop. Low wind speeds allow air to remain still over an extended period of time and absorb the characteristics of the source location, such as heat or cold.
Winds transport the climatic conditions (hot or cold, dry or wet) of the air masses they move from the source region to the destination region. A conflict with an air mass with a different temperature and humidity level may occur when the air mass enters a new area. Severe storms may result from this.
Based on where they form across the Earth, meteorologists may identify specific air masses. Arctic, tropical, polar, and equatorial are the four divisions of air masses.
Therefore the correct option is C.

Do you think a moving skateboard has energy? Why or why not?
PLEASEEEEEE HURRY
Answer:
"Yes," a moving skateboard has energy.
When the skater seems to be in motion or throughout a movement, the potential energy converts itself into the kinetic form of energy, and then it becomes potential energy again.
Furthermore, somewhere after every movement, the same skateboarder was around a similar height, — in other words thus every time it is equally powerful.
The response is thus the right one.

When a chemical reaction does not occur, what happens to the atoms of the two substances? Provide an example from Sim as evidence to support your answer.
Answer:
Explanation:A chemical response is a chemical transformation in which two chemicals combine to create a third component.
(i) Adding diluted acid to an active metal causes the test tube to heat up and hydrogen gas to escape, which results in the production of heat.
(ii) When diluted hydrochloric acid is added to silver nitrate, AgCl, a white precipitate, results.
(iii) When water is added to quicklime, the mixture boils and produces heat along with a hissing sound.
(iv) Thermal breakdown of mercury oxide - Mercury turns from red to a metallic silver tint as a result of this process.
