adelaide sorted mineral samples into two groups: dull and shiny. which of the following properties did adelaide use to separate mineral samples into group?
Answer:
B. luster
Explanation:
This is about physical properties used in classification of minerals.
The four basic properties used to identify minerals from the ground are;
1) Luster; this is a property which shows how well the reflection occurs when a mineral is exposed to light.
2)color; different minerals have different colors and this is a good property to identify minerals.
3) diaphaneity; this is defined as the ability of a mineral to have light transmitted through it.
4) shape: this is also a good property to identify minerals.
There are other properties used to identify minerals like streak which is the colour of the powdered form of a mineral, hardness, fracture e.t.c.
Now,we want to classify the mineral samples as either dull or shiny. For a mineral to be dull, it means it will not be able to reflect light properly whereas if it is shiny, light will easily be reflected from it.
The only property of minerals in the options that corresponds with shiny or dull is the Luster property.
Thus, option B is correct.

Lincoln rejected the suggestion.

Assuming the kittens on the stairs all have the same mass, which kitten has the most gravitational potential energy? Question 5 options: kitten 1 kitten 2 kitten 3 kitten 4 kitten 5
Answer:
Assuming 5 stands above all of them.
5>4>3>2>1
Explanation:
As gravitational potential energy is the measure of energy in a body due its position from the earth surface so kitten 5 is high from all others so it will have the highest potential energy.
Gravitational Potential Energy = mgh
m=mass
g= constant for all.
h= it is varying in this case.
Let us assume height of kitten 5, 4, 3, as 5m, 4m,3m so on
Gravitational Potential Energy (5) = mg5
Gravitational Potential Energy (4) = mg4
So the kitten which is at the top will have the highest Gravitational potential energy.

Read the quote from President Wilson’s letter to the National Child Labor Committee. "As the labor situation created by the war develops I am more interested than ever, if that were possible, in throwing all the safeguards possible around the labor of women and children." The "labor situation" Wilson refers to most likely concerned him because: going to war meant US industry had to begin manufacturing military supplies. women and children had to do the jobs of male workers who became soldiers. no one was left to support families when men enlisted and went to war. women and children had to replace striking factory workers.
Answer:
B
Explanation:
Women demonstrated that they could perform “men's work” to a high standard during the Second World War. Thus, option C is correct.
What are the labor situation referred by Wilson?Wilson backed and signed into law the Adamson Act, which secured an eight-hour workweek for railroad workers after American railroad unions threatened to strike in 1916. This act paved the way for shorter workdays for all industrial workers.
When males were recruited to military duty and the demand for war materials increased, women were granted access to manufacturing jobs.
For the soldiers, they made blankets, fixed shoes, laundered clothing, and sewed uniforms. Giving sick and injured soldiers medical attention during the conflict was arguably the most significant role played by women.
Therefore, women and children had to do the jobs of male workers who became soldiers.

the three numbers are in the ratio 2 : 3 : 4. the sum of their cubes is 33957. find the numbers.
Answer:
14, 21 and 28
Explanation:
2 : 3 : 4 - find the total of the numbers in the ratio cubed
2³ + 3³ + 4³ = 99 - divide 33957 by the total (99)
33957 ÷ 99 = 343 - cube root 343
∛343 = 7
This means we have to multiply each number in the ratio by 7 to find the answers:
2 × 7 = 14, 3 × 7 = 21, 4 × 7 = 28
Answer: 14, 21, and 28
Check:
14³ = 2744, 21³ = 9261 and 28³ = 21952. 2744 + 9261 + 21952 = 33957

table salt can be separated into sodium and chlorine. sodium is explosive. chlorine is a gas that can kill people. what can be concluded from the statements above?
Answer:
B. A harmful compound can become harmful when its elements are seperated.
Explanation:
In the question, common table salt, NaCl was the illustration.
NaCl is a crystalline solid whjch has different benefits like for preservation, add taste to foods etc. NaCl is generally consumed by humans daily and is found readily. This goes to show that NaCl is a harmless compound but the individual elements that is, Soduim and Chlorine gas,
2Na + Cl2 --> NaCl
Soduim metal is a reactive and unstable element with 1 (valence) electron in its outer shell. Hence why the reaction of sodium strips with water is explosive.
Chlorine gas is very poisonous, unstable as well as reactive because of the 7 (valence) electrons in its outermost shell.

When individuals tend to portray the fact that they know that an event would occur before happening is called hindsight bias. This declaration or thought about their awareness is only made known after the event had occurred.
