Answer:

75 Nm or 75 Joules

Explanation:

Dari pertanyaan tersebut, kami telah diberikan parameter berikut:

F1 = 10N

F2 = 5N

D = 5 Meter.

Kita diminta untuk mencari atau menghitung usaha yang dilakukan pada benda oleh dua gaya.

Rumus kerja yang dilakukan pada suatu benda dengan dua gaya =

W = (F1 + F2) × D

Dimana D = Perpindahan benda

W = (10N + 5N) × 5m

W = 15N × 5m

W = 75Nm atau 75Joules

Oleh karena itu, usaha yang dilakukan pada benda tersebut dengan dua gaya = 75Nm atau 75 Joules

Answer: The stick model method

Answer:

D. The stick model method

Explanation:

Protons are the subatomic particles which has positive charge.

The protons define the element.

So for example, every element that has 1 proton is hydrogen.

Hydrogen is a gas.

Every element that has 23 protons would be vanadium.

Vanadium is a chemical element with an atomic number 23.

Answer:

Chemical digestion involves the secretions of enzymes throughout your digestive tract. These enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts. Digestion involves taking large portions of food and breaking them down into micronutrients small enough to be absorbed by cells. Chewing and peristalsis help with this, but they don’t make particles small enough. That’s where chemical digestion comes in.

Chemical digestion breaks down different nutrients, such as proteins, carbohydrates, and fats, into even smaller parts:

Fats break down into fatty acids and monoglycerides.

Nucleic acids break down into nucleotides.

Polysaccharides, or carbohydrate sugars, break down into monosaccharides.

Proteins break down into amino acids.

Explanation:

In order to go from mass of magnesium to atoms of magnesium, we have to do two things:

   Convert mass of Mg to moles of Mg using the molar mass of Mg as a conversion factor

   Convert moles of Mg to atoms of Mg using Avogadro's number (6.02×1023) as a conversion factor

Step 1:

Before we start, I should note that the molar mass of Mg is 24.31gmol. We can go from mass to moles using dimensional analysis. The key to dimensional analysis is understanding that the units that you don't need any more cancel out, leaving the units that are desired:

48.60g

×1mol24.31g

=2.00mol

Step 2:

We'll use this relationship:

www.sprinklernewz.uswww.sprinklernewz.us

Using the moles of Mg that we just obtained, we can use Avogrado's number to perform dimensional analysis in order to cancel out units of mol to end up with atoms of Mg:

2.00mol

×6.02×1023atoms1mol

=1.204×1024atoms

Thus, 48.60g of Mg is equivalent to 1.204×1024atoms

Hope this helped :)

Answer:The answer is C:two or more forms of an atom that contain different numbers of neutrons. An isotope is when there are different forms of an atom, in terms of neutrons. Not to be confused with cations or anions, which are atoms with a difference of electrons or protons, making them charged.

He walked  the distance of: = 184 m

Answer:

Independent variable: Different tyre treads

Dependent variable: Breaking distance

Constant: Same car

Explanation:

In an experiment, an independent variable is that variable which the experimenter controls or manipulates to effect an outcome. In this experiment, the tyre treads are changed to see if it would affect the breaking distance, hence, the DIFFERENT TYRE TREADS is the independent variable.

On the other hand, a dependent variable is the variable that responds to the manipulation of the independent variable. In other words, it is the outcome of the experiment. In this experiment, the BREAKING DISTANCE is the responding or dependent variable.

Constant or controlled variable is that variable that is kept constant or unchanged throughout the course of the experiment. The constant, if changed, will influence the result of the experiment. The constant in this experiment is the CAR since the same car (unchanged) was used for the experiment.

Answer:

Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. ... Anodizing is accomplished by immersing the aluminum into an acid electrolyte bath and passing an electric current through the medium.

Answer:

Anodising is a process of forming a thick oxide layer of aluminium. Aluminium develops a thin oxide layer when exposed to air.  This Aluminium oxide coat makes it resistant to further corrosion. The resistance can be improved further by making the  oxide layer thicker. During anodising, a clean aluminium article is made the anode and is electrolysed with dilute sulphuric acid. The oxygen gas evolved at the anode reacts with aluminium to make a thicker protective oxide layer. This oxide layer can  be dyed easily to give aluminium articles an attractive finish

Answer:  

In this case the mass number would be 11.

Explanation:

The mass number of an element is the sum of the protons and neutrons. The number of neutrons for a given element is the only number that can change and still have the identity of the element stay the same, (because the atomic number is the number of protons).

✅Models are approximations and omit details, but a good model will robustly output the quantities it was developed for. Models do not always predict the future. This does not make them unscientific, but it makes them a target for science skeptics. ... But correct predictions alone don't make for a good scientific model

Answer:

maltose

Explanation:

If we intend to determine the largest molecule, then we must look at the relative molecular mass of each molecule because the larger the molar mass, the larger the molecule.

Hydrogen =2 gmol-1

Carbon dioxide = 44 gmol-1

Ammonia = 17 gmol-1

Maltose= 342.3 g/mol

Hence maltose is the largest molecule among the options.

Explanation:

1.A physical property is an aspect of matter that can be seen or measured without changing its chemical composition. Examples of physical properties include color, molecular weight, and volume.

A chemical property is observed only by changing the chemical identity of a substance. In other words, the only way to detect a chemical is to perform a chemical reaction.

2.This property measures the ability of chemical change. Examples of chemical properties are reactivity, flammability, and oxidation state.

The physical properties of a substance do not involve any chemical reaction. These include density, color, mass, hardness, freezing points, electrical properties, and the like.

Chemical properties include the reaction of chemicals with other substances. These reactions lead to the disappearance of the raw material and the appearance of new materials that have different physical and chemical properties.

3.Chemical properties can be compared to physical properties; On the contrary, they are recognizable without changing the structure of matter. However, for many properties in the field of physical chemistry and other disciplines at the boundary between chemistry and physics, the distinction can be a matter for the researcher's point of view. The properties of materials, both physical and chemical, can be seen as metaphysical; This means that it is secondary to the principle of tangible reality. Multiple metamorphic layers are also possible.

Density=6×24=144g/cm^3.

Answer:

0.25 g/mL

Explanation:

Density = mass/volume

Volume = 24.0 mL

Mass = 6 grams

Density = 6 grams/24.0 mL

Density = 0.25 grams/mL

The liquid expands as its temperature increases like stated. This is the same as saying that it occupies more space as temperature increases. Therefore it 'uses up' more of the space inside the thermometer as the temperature increases. the relation with kinetic energy is through the kinetic energy being used as it flows and expands, because of the heat, and mercurys relationship with heat. sorry if that's off :/
