if anybody knows these 3 answer plz

Answer:

(see below)

Explanation:

Using process of elimination:

A) lose energy

When a liquid freezes into a solid, the particles move a lot slower because the once-flowing particles are now about to be stuck in place, barely vibrating in its structure.

So, yes, they has lost energy, but there can be a better answer.

B) gain energy

When a liquid freezes into a solid, the particles move a lot slower, so there is no way there is more energy now. If there was to be more energy, it would be a gas now.

So, no, they did not gain energy.

C) move faster

When a liquid freezes into a solid, the particles move a lot slower, so there is no way they're moving faster now. Otherwise it would be a gas now.

So, no, they did not move faster.

D) disappear

Particles of a substance don't just . . . disappear. There is no way matter can be destroyed or created, only changed in form, according to the Conservation of Matter.

So, no, they did not disappear.

So the answer is most likely A.

Explanation:

Phosphodiester bonds found between the monomers on the different strands of DNA.

Deoxyribonucleic acid is called as DNA. The molecule found inside cells that carry the genetic material necessary for an organism to develop and function. This knowledge can be passed on from one generation to the next thanks to DNA molecules.

The information molecule is DNA. It contains information needed to create proteins, which are other big molecules.

In DNA polymers, phosphodiester bonds link the 5' carbon of one nucleotide and the 3' carbon of another nucleotide. In a DNA polymer, phosphodiester bonds strong electromagnetic attractants join the nucleotide monomers together.

Thus, Phosphodiester bonds found between the monomers on the different strands of DNA.

Explanation:

Water which is a liquid becomes ice which is a solid

That would be C, due to the fact that the water changes from a liquid to a solid. (I hope that helped ^^)

Answer:

Explanation:

Each time you add a neutron, it adds one mass number to the mass because each neutron and proton weighs approximately 1 amu.

Answer:

The mass increases

Explanation:

When protons and neutrons are added, the mass increases. Electrons, on the other hand, are so small they do not affect the mass.

Answer:

Independent variable: SIZE OF NAILS

Dependent variable: NUMBER OF PAPER CLIPS

Explanation:

The independent variable in an experiment is the variable that is changed or manipulated by the experimenter in order to effect a measurable response. In this investigation, the DIFFERENT SIZES OF NAILS USED is the INDEPENDENT VARIABLE.

The dependent variable is the variable that is measured in the experiment. It is the variable that responds to changes made to the independent variable. In this investigation, THE NUMBER OF PAPER CLIPS the electromagnet could pick up is the DEPENDENT VARIABLE.

The dependent variable is the number of paper clips that the electromagnet could pick up while the independent variable is sizes of nail used.

An experiment consists of;

The independent variable is the variable that is being manipulated while the dependent variable changes with changes in the independent variable.

In this experiment, the dependent variable is the number of paper clips that the electromagnet could pick up while the independent variable is sizes of nail used.

Explanation:

They describe different forms of matter, solid and liquid. As well as both being entirely differently structured forms of matter.

They distinguish between solid and liquid matter. In addition to being completely different types of matter.

Matter is defined as everything that takes up space other words, the "material" that makes up the universe.

All matter is composed of substances known as elements, each of which has unique chemical and physical properties and cannot be decomposed into other materials through ordinary chemical reactions.

Atoms and molecules make up some of the material in the category of solids, liquids, and gases.

The matter that makes up wood have characteristics of any solid, i.e., high intermolecular force of attraction that holds it shape.

The matter that is making water will have liquid characteristics, which do not have a particular shape and will have weak intermolecular forces of attraction.

Thus, this is the chief difference between the "matter that makes up wood" and the "matter that makes up water".

a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction

Answer:

First Question:

Melting is a physical process that involves the phase transition of a substance from its solid to its liquid state. Burning, on the other hand, is a chemical process that involves a substance being broken down and changed into different substances. It's still the same substance, though: water.

Second Question:

Mass is therefore never conserved because a little of it turns into energy (or a little energy turns into mass) in every reaction. But mass+energy is always conserved. Energy cannot be created out of anything.

Explanation:

Mendeleev's holes have long since been filled in and new elements have been added to the periodic table.

Periodic table is defined as a list of chemical elements that are ordered in atomic number order, typically in rows, with comparable chemical elements appearing in vertical columns because of their similar atomic structures. The table can be used by scientists to anticipate chemical reactions, study trends in the periodic properties of certain elements, and speculate on the properties of yet-to-be-discovered elements.

The structure for the contemporary periodic table was developed in 1869 by Russian chemist Dmitri Mendeleev, who left spaces for elements that had not yet been discovered. He organized the elements into groups based on their atomic weight, rearranging them if necessary if he found that they did not fit.

Thus, Mendeleev's holes have long since been filled in and new elements have been added to the periodic table.

C. Total energy :  1.9878 x 10⁻²⁰ J

The photoelectric effect is an electron coming out of a metal because of electromagnetic radiation

One type of electromagnetic radiation is light

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

[tex]\large{\boxed{\bold{E\:=\:h\:.\:f}}}[/tex]

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves

f = c / λ

c = speed of light

= 3.10⁸

λ = wavelength

A. wavelength

[tex]\tt \lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3.10^8}{1.10^8~Hz}=3~m[/tex]

Explanation:

Now let us take a recap of Joelle's criteria for a wall filling material;

1) the material must be a thermal insulator

2) materials should not be acidic

3) they will not dissolve too easily in water.

If we consider the options provided, Na6Ba6  and NeNa do not exist. HCl is an acid and does not match Joelle's criteria. Hence the answer must be C6H6.
