Answer:

Explanation:

arranged in order of increasing.

Answer:

42.3529412 m/min or 0.705882353 m/s

Explanation:

We can calculate speed using the following formula.

[tex]s=\frac{d}{t}[/tex]

where [tex]d[/tex] is distance and [tex]t[/tex] is time.

The Olympic swimmer can swim 360 meters in 8.5 minutes. Therefore,

[tex]d= 360 \ m \\t= 8.5 \ min[/tex]

Substitute the values into the formula.

[tex]s=\frac{360 \ m}{ 8.5 \ min}[/tex]

Divide.

[tex]s= 42.3529412 \ m / min[/tex]

Her speed is 42.3529412 meters per minute.

If we want to find her speed in meters per second, convert the minutes to second.

1 minute is equal to 60 seconds, so we can multiply 8.5 by 60.

[tex]8.5 *60=510[/tex]

The swimmer can swim 360 meters in 510 seconds.

[tex]s=\frac{d}{t}[/tex]

[tex]d= 360 \ m \\t= 510 \ s[/tex]

[tex]s=\frac{360 \ m}{510 \ s}[/tex]

[tex]s=0.705882353 \ m/s[/tex]

Her speed is also 0.705882353 meters per second.

Answer: 0.5g/ml

Explanation:

The density of a substance is given by the following formular; Mass / Volume,

Where mass = 10g

           volume = 20ml

Density = 10g/ 20ml = 0.5g/ml

Answer:

pretty sure its Scientific laws are statements about observed experimental facts, while theories are explanations of natural phenomena.

The statement that correctly explains the difference between a theory and a scientific law is as follows:

Thus, the correct option is B.

A Scientific theory may be defined as a well-explained fact that is significantly associated with the natural world that has been constructed through the utilization of the scientific method, and which brings together many facts and hypotheses.

A Scientific theory is based on observation. It is proven but still testable in nature in order to derive evidence. It generally does not possess mathematical statements and deductions. Theories are explained on nature as well as natural phenomena.

Scientific law is based on unalterable facts or those facts that remain constant. It is proven as well as contains evidence to support the claim. It definitely possesses mathematical statements and deductions.

Therefore, the correct option for this question is B.

Density is mass divided by volume.

Since mas is 0.5kg we need to convert it to grams. Using conversion factors we get the mass of the bread to be 500g.

So densty=500/2500

density =1/5 grams per cubic centimeter

Answer:

Matter can be classified according to physical and chemical properties. Matter is anything that occupies space and has mass. The three states of matter are solid, liquid, and gas. A physical change involves the conversion of a substance from one state of matter to another, without changing its chemical composition.

Explanation:

Answer:

Described in the explanation section

Explanation:

Ice is the solid phase of water and this phase, the water molecules usually have very little energy and therefore can't detach from each other. This is because the water molecules are closely packed together in a regular arrangement normally called lattice.

Now, when the ice is heated to become a liquid, the energy of the water molecules increases and thus some of them will have enough energy to overcome the intermolecular forces that had been keeping them closely packed in the ice phase. This will then make the water molecules to move further apart thereby forming liquid water.

Now, when the molecules are heated further, the liquid water will now turn into water vapor, which is the gas phase of water. The molecules in this gas phase will have more energy than in the liquid phase because the average distances between each of them will be much larger than the size of the molecules themselves.

Answer:

heated or cooled

Explanation:

Matter can change from one state to another if heated or cooled.

Answer:

Many things can change a substance from one state to another. These things include pressure, temperature, frequency, and many more.

Answer:

Explanation:

zn is oxidized because its oxidation number is increased from zero in zn to +2 in zn(No3)2

Ag is reduced because its oxidation number is reduced from +1 in AgNo3 to zero in Ag

oxidation number of zn(s) is zero while the oxidation number of zn in zn(No3)2  is

zn(No3)2=x+(5*2)+(-2*6)=x+10-12=x-2

x-2+2=2

x=2

the oxidation of Ag in AgNo3

AgNo3=x+5+(3*-2)=x+5-6=x-1

x-1+1=1

x=1 while the oxidation number of Ag is zero

so zinc is oxidized and silver (Ag) is reduced

Answer:

Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.

(Sorry I had to answer twice it was because of LukeG1).

Answer:

The answer is

Explanation:

The density of a substance can be found by using the formula

[tex]Density = \frac{mass}{volume} [/tex]

From the question

mass = 67 g

Volume of ring = new volume of water - original volume of water

Volume = 13.47 - 10 = 3.47 mL

Substitute the values into the above formula and solve

That's

[tex]Density = \frac{67}{3.47} \\ = 19.308357[/tex]

diamonds

Explanation:

Diamond does not conduct electricity.  

• A form of carbon in which each of the atom of carbon is joined to four other atoms of carbon, giving rise to a giant covalent composition is a diamond.  

• Due to this, diamond is very robust and exhibits high melting point. Thus, is used to cut tools.  

• Diamond does not conduct electricity, due to the absence of delocalized electrons in the structure.  

Thus, diamond does not conduct electricity. Option d is correct.

His measurements will be more precise if he uses a graduated cylinder that measures to the nearest tenth of a mL.

Explanation:

His measurements will be more accurate if he uses a graduated cylinder that measures to the nearest tenth of a mL. The correct option is B.

The closeness of a measurement to the real or recognised value is referred to as accuracy.

The learner can achieve more exact measurements and eliminate the possibility of rounding mistakes by using a graduated cylinder that measures to the closest tenth of a millilitre.

This enhanced precision will help to improve measurement accuracy. Taking measurements from more flowers (options A and D) will expand the sample size but will not enhance accuracy unless the measuring device is updated.

Option C recommends improving precision but does not address accuracy.

Thus, the correct option is B.
