Andi performs the calculation that is shown below.
(2.06)(1.743)(1.00)
How should the answer be reported using the correct number of significant figures?

Answers

Answer 1

Answer: 3.59

Explanation:

(2.06)(1.743)(1.00)

2.06 × 1.743 × 1.00

= 3.59058

Two of the multiplied digits are represented in 3 significant figures. Therefore, for correct representation, the result of the product should be written to three significant figures.

3.59058 to 3 significant figures:

First three digits = 3.59

Fourth digit '0' is less than 5, and thus rounded to 0 with other succeeding digits

Therefore, (2.06)(1.743)(1.00) to 3 significant figures equals :

3.59

Answer:

Explanation:

An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 - 11 this atom will have 12 neutrons. Since this atom is neutral the positive protons must be equal to the negative electrons. This atom will have 11 electrons

Answer:

Sodium: Na

It is a metal

It's family is Alkali metals

Its atomic number is 11

It has 12 neutrons, 11 protons, 11 electrons

3. A recent flood in the area has caused many short-term changes to
the ecosystem. Which is a long-term change?
A. Standing water in the streets and sewers
B. Temporary displacement of organisms
C. Permanent change in the landscape
D. Poor water quality in rivers and streams

Answers

Answer:

Explanation:

While standing water in the streets and sewers (option A) and poor water quality in rivers and streams (option D) may persist for some time after the flood, they are generally considered short-term changes as they can eventually be remedied through clean-up efforts and restoration programs.

Temporary displacement of organisms (option B) can also be considered a short-term change, as organisms will eventually return to their original habitats once conditions improve.

However, a permanent change in the landscape (option C) such as altered river channels, new water bodies, or changes in topography, can have lasting effects on the ecosystem and its inhabitants. These changes may alter habitat suitability, nutrient cycling, and water availability, which can impact the ecosystem for years or even decades to come.

Answer: C

Explanation:

The landscape could be flooded. Houses and buildings may be restricted.

this is the question and i dont know which reasoning i should use for the claim "If you follow the instructions, the POW kits will always heat the water above the correct temperature for pasteurization (65°C), but some people didn’t follow the instructions."

Answers

Answer:

I think this evidence supports this claim because Evidence Card b says “One man got sick, but his two children did not. He used water from Whip River. He used the cube to heat the first pitcher of water, which he gave to his kids, and then reused the cube without reheating for the second pitcher, which he drank himself.”

Explanation:

The correct reasoning for the given claim is shown by evidence 2.

What is water pasteurization?

Pasteurization is a method of disinfecting water without boiling it using heat or radiation.

Evidence 2 is the correct reasoning to explain the fact that if we follow the instructions the kit will always heat the water above the correct temperature for pasteurization (65°C). Second evidence is that “One man got sick, but his two children did not. He used water from Whip River. He used the cube to heat the first pitcher of water, which he gave to his kids, and then reused the cube without reheating for the second pitcher, which he drank himself.”

Hence evidence 2 is the correct reasoning.

What are the organelles in the cell?

I can see that your question has to do with the organelles in the cell but I don't quite get the analogies that you intend to use. However, I would explain the organelles one after the other.

Endoplasmic reticulum: The endoplasmic reticulum (ER) is a network of membranous tubes and sacs within the cytoplasm of eukaryotic cells. It serves as a transport system for proteins and lipids, as well as a site for folding and modification of newly synthesized proteins.

Ribosomes: Ribosomes are complex molecular machines that are found in the cytoplasm of all living cells. They are responsible for synthesizing proteins from amino acids, which are the building blocks of proteins.

Mitochondria: These are organelles found in the cytoplasm of eukaryotic cells. They are often referred to as the "powerhouses" of the cell because they are responsible for producing most of the cell's energy in the form of ATP (adenosine triphosphate).

Vacuole: Vacuoles are membrane-bound organelles found in eukaryotic cells. They are large, fluid-filled compartments that serve several important functions within the cell, including storage of nutrients and waste, regulation of the cell's water balance, and maintenance of cell shape.

Cytoplasm: Cytoplasm is the gel-like substance that fills the interior of eukaryotic cells, excluding the nucleus. It is a complex mixture of water, ions, organic molecules, and a variety of cellular structures, including organelles such as mitochondria, ribosomes, endoplasmic reticulum, and lysosomes.

Lysosomes :Lysosomes are membrane-bound organelles found in eukaryotic cells. They are referred to as the "garbage trucks" of the cell because they are responsible for breaking down and recycling cellular waste and unwanted material.

What needed to be present in marine mud to form fossil fuels?

Answers

Carbon and Hydrogen.

Answer:

Mostly decaying organisms are needed to present in marine mud to form fossil fuels.

Explanation: When organisms and plants died and sank to the bottom of swamps and oceans, brown soil-like materials called peat are formed. Over millions of years, the peat became covered with sand, clay and other minerals and the peat is converted into layers of sedimentary rocks. After a long time, different type of fossil fuels are formed.

Write the roman numeral atomic name from the chemical formula.

Answers

The chemical formula VI3 is composed of an unknown element with the symbol "V" and three atoms of iodine. It is not a common compound, as there is no element with the symbol "V". Therefore, it is not possible to write the Roman numeral atomic name from this formula.

The chemical formula SnO2 represents tin(IV) oxide, which is composed of one tin atom and two oxygen atoms. To write the Roman numeral atomic name from this formula, we can follow these steps:

Sn: tin

O: oxygen

The oxidation state of Sn is +4, and the oxidation state of O is -2.

To determine the Roman numeral atomic name, we need to find the charge on the cation (Sn) that balances the charge on the anion (O). Since the charge on two O atoms is -4, the charge on Sn must be +4 to balance the charge.

The Roman numeral for +4 is IV.

Therefore, the Roman numeral atomic name for SnO2 is tin(IV) oxide.

Answer:

atomic name snO2 = Tin (IV) oxide

This is a bio question not chemistry btw

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)

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
