A student wanted to test how the mass of a paper airplane affected the distance it would fly. Paper clips were added before each test flight. As each paper clip was added, the plane was tested to determine how far it would fly.
What was the dependent (outcome) variable from this experiment?
The paper airplane design.
The number of paperclips.
The type of paper.
The distance the plane flies.
Answer:
The distance the plane flies.

The three cyclists shown below are all traveling at a speed of 13 m/s, but only one cyclist has a changing velocity. The orange cyclist is on the curve, and the green and blue cyclist are on the straight away. Select the rider that has a changing velocity.
(btw the extra tab is to cover my info)
The orange one is changing direction while the rest cyclists are increasing displacement.
What is Velocity?Velocity is defined as the directional motion of an object as an indication of the rate of change of position as observed from a particular frame of reference which is measured by a particular standard of time. Velocity is the vector quantity as it has both direction as well as direction.
Velocity is explained as the displacement/time where the displacement being the change in position. In the above given example, the orange color cyclist's position is not changing as he is changing direction.
Thus, the orange one is changing direction while the rest cyclists are increasing displacement.

Guadalupé’s Argument:
Christchurch’s air temperature is cooler than usual during El Niño years because the prevailing winds are disrupted and the currents change. Therefore, the change in air temperature is caused by changing winds and currents.
Anthony’s Argument:
Christchurch’s air temperature is cooler than usual during El Niño years because the prevailing winds are disrupted. This evidence matters because prevailing winds push the warm currents that pass Christchurch. These currents carry energy, and that energy is transferred to the air, which makes the air warmer. When prevailing winds are disrupted, they do not push the currents toward Christchurch, so the energy transfer does not happen. This makes the air temperature cooler. Therefore, the change in air temperature is caused by changing winds and changing currents.
Who's argument is more convincing?
Guadalupé’s or Anthony's

How is density different from weight and mass?
Hello there!
How is density different from weight and mass you say? It's simple!
1. Unlike weight, density is composed of mass and volume.
2. By dividing the mass over the volume, you can determine an object's density, while weight is the product of mass and gravity.

Which of the following is NOT a reason atom economy is important?
A. Minimize waste of non-renewable reactants
B. To reduce the amount of water used in cooling reactions
C. Make as much product as possible
D. Increase energy use during reactions
Reset Selection
Answer:
Increase energy use during reactions
Explanation:
Answer via Educere/ Founder's Education
Increase energy use during reactions. Hence, option D is correct.
What is an atom?An atom is any particle of matter at its most basic level which contains at least one proton.
A reaction with a high atom economy is important in industry because it uses lesser natural resources, produces less waste, and is better for the environment. It is also cheaper to produce and more sustainable.
Increasing energy used during reactions is NOT a reason atom economy is important.
Hence, option D is correct.

In the following images, a blue circle represents an atom of one type of element, and a red square represents an atom of a second type of element. Determine which of them represent a pure substance, a homogenous mixture, and a heterogeneous mixture.
Are these in the right order?
Answer: No they are not. "Pure substance" is supposed to be placed in the middle picture. "Homogenous mixture" is supposed to be placed in the right picture. "Heterogenous mixture" is supposed to be placed in the left picture.
Explanation:
Pure Substances:
There are two categories of pure substances: elements and compounds (In our case, we have a compound).
Element (e.g. the blue circles or the red squares):
An element is a fundamental substance.An element cannot become simpler than itself, even if chemical separation methods are used.Compound (e.g. the blue circles bonded together with the red squares in the middle picture):
A compound is a substance made of two or more elements in fixed proportions (i.e. One element has the same amount as the other).A compound can be made into individual elements or simpler substances using chemical methods of separation.Mixtures:
There are two categories of mixtures: homo- and hetero- genous.
Homogenous mixture:
The substances or elements are mixed to look like one single substance and cannot be told apart (e.g. When salt dissolves in water, the water still looks like water).The substances or elements are distributed evenly throughout the apparatus. The number of different types of substances or elements can vary (e.g. There is more water than salt) The substances or elements do not bond together.Heterogenous mixture:
The substances or elements are mixed and can be told apart (e.g. When oil is mixed with water, the oil is "water-hating" so it forms its own layer on the bottom, while the water forms another layer on top of the oil layer).The substances or elements are distributed where one type of substance or element is bunched up in one spot and another substance or element in another spot.The number of different types of substances or elements can vary.The substances or elements do not bond togetherThe second Image is not a homogenous mixture, it is a heterogenous mixture as two different types of elements are mixed together.
The mix of two different types of elements in the heterogenous mixture is not uniform and has uneven mixed types.
The third image is a homogenous mixture as even though two different types of elements are together, they are not mixed with each other.
Unlike in the heterogenous mixture, in a homogenous mixture, there is a uniform mix of two different types of elements.
The first image is correct, the image depicts a pure substance.
