1156 g/L
= ________ kg/mL
Answers
The Answer is 0.001156.
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.

Which items are biomass energy sources? Select all correct answers.
the sun
wood chips
manure
paper
Answers
Answer:
wood chips, paper, and manure are biomass energy sources.
Explanation:
Biomass energy is energy generated or produced by living or once-living organisms.
Wood chips, paper, and manure are biomass energy sources. The primary form of energy from renewable sources that can be utilised to replace fossil fuels on a long-term basis is biomass.
Energy created or generated by living or formerly living creatures is known as biomass energy. Plants like the aforementioned maize and soy are the most prevalent types of biomass that are utilised for energy. These creatures' energy may be used to generate electricity or be burnt to provide heat. Direct combustion is the primary method of producing most of the power from biomass. In a boiler, biomass is burnt to create high-pressure steam. These turbine blades revolve as a result of the steam flowing over them. Wood chips, paper, and manure are biomass energy sources.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

What happens to the atoms that make up hydrogen fuel as it burns?
Answers
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

Which of the following best explains the relationship between peak-to-peak amplitude and semi-amplitude?
Answers
Answer:
A. Semi-amplitude is half the distance of the peak-to-peak amplitude
Explanation:
The correct answer is : The semi-amplitude is half the distance of the peak-to-peak amplitude (option A). The peak-to-peak amplitude is the total distance between the highest positive peak and the lowest negative peak in a waveform. It represents the full range of variation in the amplitude of the waveform.
The peak-to-peak amplitude of a waveform is the measurement of the total distance between the highest positive peak and the lowest negative peak. It provides information about the full range of variations in the amplitude of the waveform. Mathematically, it is calculated by subtracting the minimum value from the maximum value of the waveform.

The standard reduction potential for the half-reaction of Be^2+ + 2e^- -> Be is given as E^0 = 3.83 V.
For the half-cell Hg^2+ | Hg, the standard reduction potential is not provided in the given information. To calculate the electric potential for the voltaic cell, we need the reduction potential for the Hg^2+ | Hg half-cell.
A voltaic cell, also known as a galvanic cell or an electrochemical cell, is an electrochemical device that generates electrical energy through a spontaneous chemical reaction. It consists of two half-cells connected by an external circuit and a salt bridge or porous barrier that allows the flow of ions between the two half-cells.
Each half-cell consists of an electrode immersed in an electrolyte solution. The electrode is typically made of a metal or a conductive material, and the electrolyte is a solution containing ions that can participate in the redox (reduction-oxidation) reaction.

Develop models bonds can be placed on a scale that ranges from 100% ionic to 100% covalent. Use what you know about the types of bonds that specific elements tend to form to place each of the following compounds in the correct location on the scale: CO2, N2 , NaF, H2O
Answers
Answer:
Bonds can be placed on a scale that ranges from 100% ionic to 100% covalent.
CO2: CO2 is a covalent compound, with each carbon atom sharing electrons with two oxygen atoms. Therefore, it can be placed closer to the 100% covalent end of the scale.
N2: N2 is a covalent compound, with each nitrogen atom sharing electrons with another nitrogen atom. Therefore, it can be placed closer to the 100% covalent end of the scale.
NaF: NaF is an ionic compound, consisting of a sodium cation (Na+) and a fluoride anion (F-). Therefore, it can be placed closer to the 100% ionic end of the scale.
H2O: H2O is a polar covalent compound, with the hydrogen atoms sharing electrons with the oxygen atom, but the electrons are not shared equally, therefore the oxygen atom has a partial negative charge and hydrogen atoms have a partial positive charge. Therefore, it can be placed closer to the middle of the scale, between ionic and covalent.
Overall, the scale can be represented as follows:
100% Ionic <-------> NaF <-------> H2O <-------> CO2 <-------> N2 <-------> 100% Covalent
What are some ways your body regulates the increase of body temperature that also occurs when exercising?

What is effect of exercising on body temperature?
Our muscles quickly deplete stored energy when you start exercising. To make more energy, muscles combine oxygen with adenosine triphosphate or ATP. This process creates heat energy as a byproduct. Muscles generate the most heat because they produce so much energy.
Extra heat raises your body temperature, so your body needs to eliminate heat as quickly as possible.
Therefore, some ways by which your body regulates the increase of body temperature that also occurs when exercising are evaporation of sweat and skin blood flow.
