Answer:
Principle stating that specific groups of organisms have followed, or succeeded one another in a definite sequence through Earth history
Explanation:
Principle stating that specific groups of organisms have followed, or succeeded one another in a definite sequence through Earth history describe Faunal succession because it is a principle that indicate that fossil plants and animals succeed each other in a sequential manner even if they occur in different places. Successive strata and faunas are linked together to form composite section in the Earth's history.

Explanation:
A hypothetical element has two main isotopes with mass numbers of 59 and 62. If 73.00% of the isotopes have a mass number of 59 amu, what atomic weight should be listed on the periodic table for this element? Answer in units of amu.
since 73% of the isotope is given, take 100%-73% to get the remaining % of the isotopes which is going to be 27%.
hence,
atomic weight= (73×59) + (27×62)
=4307+1302
=5609 amu

You are standing at position X. Choose the diagram that shows your position when you perceive a sound lower than the actual pitch of the siren.
Answer:
The answer is the second picture.
Explanation:
When you perceive a sound lower than its actual pitch, then you must have been further from the actual position.
What is pitch of a sound?
The pitch of a sound is a perceptual property of sounds that allows sound of similar frequencies to be distinguished.
Pitch is the quality of sound, that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical notes.
Thus, when you perceive a sound lower than its actual pitch, then you must have been further from the actual position.

Calculate the average atomic mass of unknown element X. You determine that isotope 127X makes up 80%, isotope 126X makes up 17%, and isotope 128X makes up 3%.
A. 127.10 amu
B. 126.86 amu
C. 127.54 amu
D. 126.20 amu
Answer:
Option B. 126.68 amu
Explanation:
The following data were obtained from the question:
Isotope A (¹²⁷X):
Mass of A = 127
Abundance (A%) = 80%
Isotope B (¹²⁶X):
Mass of B = 126
Abundance (B%) = 17%
Isotope C (¹²⁸X):
Mass of C = 128
Abundance (C%) = 3%
Average atomic mass of element X =.?
Th4 average atomic mass of X can be obtained as follow:
Average atomic mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]
= [(127 × 80)/100] + [(126 × 17)/100] + [(128 × 3)/100]
= 101.6 + 21.42 + 3.84
= 126.68 amu
Therefore, the average atomic mass of X is 126.68 amu
What happens when you touch two hot bowls made of different materials? The wooden and metal bowl are both at the same temperature and HOTTER than your finger. Compare the direction and speed of the heat arrows for the wooden and metal bowl. Explain WHY and what affects HOW the arrows move from the wooden and metal bowl to the finger.
Answer:
Explanation:
Both metal and wooden bowls are at the same temperature . But wood is non-conductor of heat whereas metal is conductor of heat .
If we touch the wooden bowl , heat flows from hot to cold object . Since the finger is at higher temperature , heat flows from finger to wooden bowl . But , since wood is non conducting , it does not allow heat to be conducted through it . Hence very less heat will be conducted from our finger .
On the other hand , if we touch a metal bowl , heat flows from finger to the metal bowl , without any hinderance . Hence rate of heat flow will be fast in case of metal bowl . As a result of it , we feel cool in touching metal bowl . This feeling will be absent in case of wooden bowl.

Scientific methodology includes the following: Objective observation: Measurement and data (possibly although not necessarily using mathematics as a tool)
Explanation:
Answer:
Modern science is typically divided into three major branches that consist of the natural sciences (e.g., biology, chemistry, and physics), which study nature in the broadest sense; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences
Write down the answer. Make sure to use the correct number of sig figs or
spots after the decimal. 987.22 - 377.1*
Answer:
610.1
Explanation:
When we add or subtract the values, the number of significant figures after decimal in result must be equal to the given measurement having less number of decimal places.
In given values 377.1 has only decimal place thus in result after decimal there should be one digit only.
987.22 - 377.1 = 610.1
When we multiply or divide the values the number of significant figures must be equal to the less number of significant figures in given value.
Now we will calculate the difference between 7.69 and 4.0.
7.69 - 4.0 = 3.69
In given values 4.0 have less number of significant figures thus result must have only two significant figures . So we would round the result.

Why are atoms neutral?
A They have neutrons in the nucleus
B. They have the same number of protons and electrons
They tend to have 8 valence electrons
D
None of the above
Answer:
B. They have the same number of protons and electrons
Explanation:
Protons have a charge of +1, electrons have a charge of -1, and neutrons have no charge, making them neutral. When there are the same number of protons as there are electrons, the charges balance out, leaving you with a neutral atom.

Chloroethene,C2H3C1, reacts with oxygen according to the equation below.
2 C2H2Cl (9) + 5O2(g) + 4CO2 (g) + 2 H20 g) + 2 HCl (9)
What is the amount, in mol, of H2O produced when 10.0 mol of C2H3Cl and 10.0 mol of
O2 are mixed together, and the above reaction goes to completion?
08.00
10.0
04.00
20.0
Lo
Answer:
4.00 moles of water
Explanation:
The equation of the reaction is:
2 C2H2Cl (9) + 5O2(g) -------> 4CO2 (g) + 2 H20( g) + 2 HCl(g)
To find the limiting reactant, we find the species that yields the lowest number of moles of water.
From the reaction equation;
2 moles of C2H2Cl yields 2 moles of water
10 moles of C2H2Cl yields 10 * 2/2 = 10 moles of water
Similarly;
5 moles of oxygen yields 2 moles of water
10 moles of oxygen will yield 10 *2/5 =4 moles of water
Hence oxygen is the limiting reactant.
10 moles of oxygen yields 4 moles of water.
On July 4, 2020, America turned 7.69 x 10^9
seconds old. On that day, how old was America
in years? (Assume 365 days in a year)
America's age = 243.85 years
Further explanationWhen converting units, list and multiply all the units until you find the unit you want
Time unit conversion
1 year = 365 days
1 day = 24 hours
1 hour = 3600 s
7.69 x 10⁹ seconds to years :
[tex]\tt =7.69\times 10^9~s\times \dfrac{1`hour}{3600~s}\times \dfrac{1~day}{24~hours}\times \dfrac{1~years}{365~days}\\\\=\dfrac{7.69\times 10^9}{3600\times 24\times 365}\\\\=\boxed{\bold{243.85~years}}[/tex]

what is potiential and kinetic engergy? pls someone answer my question
Answer:
Potential Energy is stored energy or energy of position (gravitational). The object isn't moving. For example, a ball being held is potential energy because the object isn't moving but it has the potential of turning into kinetic energy.
Kinetic Energy is the energy of motion. For example, running. You are moving, and there is clear action and activity
Energy stored in an object due to its position is Potiential energy . Energy that is moving object has due to its motion is Kinetic energy .
