The force of gravity between two objects is greater when the objects have 
Answers
Answer:
Objects with greater mass have a stronger force of gravity between them.
Explanation:
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled.
SIMPLE QUESTION WORTH 25 PTS :) If water has a density of 1g/ml and gold has a density of 19.3 g/ml. Will gold float or sink in water?
Answers
Explanation:
All substances that have a density greater than that of water will sink into the water since they are heavier and those less than water will float on it since they are less than that of water
From the question
Comparing the two values the density of gold is greater than that of water therefore the gold will sink into the water

Read the excerpt from Harriet Tubman: Conductor on the Underground Railroad. She started talking about William Still and the Philadelphia Vigilance Committee. No one commented. No one asked any questions. In this excerpt, which rhetorical appeal is Tubman attempting to use to convince people to continue? Ethos, because she is using her own knowledge as a tool. Pathos, because she is appealing to her audience's needs. Ethos, because she is appealing to their emotional needs. Pathos, because she is using facts to convince her audience.
Answers
Answer:
Ethos, because she is using her own knowledge as a tool.
Explanation:
Harriet Tubman was an activist and served as a spy for Union Army. 'Harriet Tubman: Conductor on the Underground Railroad' is a book written by Ann Petry narrating the accounts of life of Harriet Tubman who helped free 300 slaves using the paths of Underground Railroad.
In the given excerpt, Tubman has used the rhetorical appeal of 'ethos' as she is using her own knowledge as a tool. While rescuing slaves using Underground Railroad, Tubman made up several stories to keep the slaves moving and encourage them in their paths of freedom. The path for freedom was dangerous, and Tubman knew that some may back up from this, so she kept telling them about people who chose to struggle for freedom, made up stories about them and used this knowledge as a tool to keep the slaves encouraged and motivated. And no one asked her even one question as they trusted her (credibility-- element of ethos).
Thus, the tool Tubman has used in the given excerpt is ethos.

5) 24.3 amu
6) 193 amu
7) 6.94 amu
Explanation:
The fractional abundance shows how many atoms of the element exist as a particular isotope with a certain mass.
To find the average, multiply the fractional abundance with the mass. All the fractional abundance should add up to 100%.
5) Average atomic mass of Mg
= 78.7%× 23.985 +10.13% ×24.986 +11.17% ×25.983
= 24.3 amu (3 s.f.)
6) Avg atomic mass
= 37.85% ×191 +62.42% ×193
= 193 amu (3 s.f.)
7) Avg atomic mass
= 7.59% ×6.015 +92.41% ×7.016
= 6.94 amu (3 s.f.)

Answers
Answer:
c
Explanation:
The one that is chemical property is flammability. The correct option is C.
What are chemical properties?Chemical properties are those properties that do not change by changing the size or shape of the elements. They are the quality that can only be formed by altering a substance's chemical identity is referred to as a chemical property, and it can occur during or after a chemical reaction.
The main chemical properties are flammability, pH, toxicity, reactivity, etc. Flammability is a property of the burning of an element. If a substance burns quickly and readily, it is flammable. If a substance does not burn quickly and readily, it is called inflammable. Some substances are wood, methanol, etc.
Thus, the correct option is C. Flammability.

Elements are organized on the periodic table based on their properties. Which statement correctly predicts and explains the chemical reactivity of two different metals? Barium (Ba) is less reactive than calcium (Ca) because the valence electrons in calcium atoms are farther from the nuclei and harder to remove. Strontium (Sr) is more reactive than magnesium (Mg) because the valence electrons in strontium atoms are farther from the nuclei and harder to remove. Rubidium (Rb) is more reactive than sodium (Na) because the valence electrons in sodium atoms are closer to the nuclei and easier to remove. Lithium (Li) is less reactive than potassium (K) because the valence electrons in lithium atoms are closer to the nuclei and harder to remove.
plz answer asap
Answers
Answer:
Lithium (Li)
Explanation:
The periodic table is the representation of the elements. According to the table, Lithium is less reactive than potassium because of the valence electrons. Thus, option D is correct.
Why is lithium less reactive?Lithium and potassium both are elements arranged in the periodic table and are placed in the same group I. The atomic number of lithium is 3, while potassium is 19.
The reactivity depends on the atomic size of the element and increases when one moves down in a periodic group. In group I, lithium has a small size as valence electrons are closer to the nucleus and harder to remove.
On the other hand, potassium has a higher atomic number and a larger size making its valence electron to be located at a larger space making them get easily eliminated.
Therefore, lithium is less reactive than potassium.
