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.

When a chemical reaction occurs, what happens to the atoms of the two substances? Provide an example from the Sim (on Amplify) as evidence to support your answer.
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.
Answers
An example of this can be seen in the Sim on Amplify, where students can experiment with different chemical reactions. For instance, in the "Chemical Reactions" Sim, students can explore the reaction between iron and sulfur to form iron sulfide. In this reaction, the iron atoms and sulfur atoms combine to form a new compound, iron sulfide, with different properties than the original iron and sulfur. The atoms of the iron and sulfur are rearranged to form new bonds, resulting in the formation of a new substance. This is an example of a chemical reaction, where the atoms of the two substances are rearranged to form a new compound with different properties.
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.

Answers
What is drag? (dont copy and paste! put it in you own words)
Answers
Answer:
aerodynamic resistance to the motion of the object through the fluid. This source of drag depends on the shape of the rocket and is called form drag. As air flows around a body, the local velocity and pressure are changed. The base area of a model rocket produces form drag.
Explanation:
Drag depends on the cross-sectional area of the object pushing through the air. Making a rocket as narrow as possible is the best way to reduce drag. The speed of a rocket through the air similarly increases drag.

Comparing the two waves, wave B has a...
A) higher frequency.
B) greater amplitude.
C) shorter wavelength.
D) longer wavelength.
Answers
Answer: D) longer wavelength.
Explanation:
As far as I know, you calculate frequency on a graph using the number of peaks you can see. Since the wavelength is shorter (the distance between two peaks on the wave), the frequency should also be higher as more fit on the graph.

What happens to the atoms that make up hydrogen fuel as it burns?
Answers
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answers
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
kinetic energy is given as
5) when speed is 6 m/s
kinetic energy is given as

The toucan uses its long beak to reach fruits and berries growing on trees in the forest. The energy stored in the fruit and berries is passed on to the toucan when it is eaten. What is the source of energy for the fruits and berries growing on the trees in the tropical forest?
A: Soil
B. Sunlight
C. Heat
D. Water
Answers
Answer:
The type of adaptations of the Toucan and Monstera Plant are physical adaptions. Both of these adapted physical characteristics help these organisms to survive. The difference in their physical adaptation is that in the Toucan, the physical characteristic helps the Toucan consume nutrients. Meanwhile, the adaptation of the Monstera Plant helps prevent harmful things such as mold.
Plants use photosynthesis to convert light into cellular energy, which allows them to make “food” out of the water and nutrients from the soil.
