Explanation:

Answer

Rotating

Explanation:

The Earth is always being pulled towards the Sun by gravity.

The Earth is not moving fast enough to "escape" the Sun's gravity and leave the solar system, but it is going too fast to be pulled into the Sun. Therefore, it keeps going around and around( roating)- orbiting the Sun.

Answer:

Rotating around the sun

Answer:

4477381.7 calories/pound

Explanation:

It is given that,

When a candle burns it produced 41,300 Joules per 1 gram.

We need to convert it into calories per pound.

We know that,

1 cal = 4.184 J

⇒ 1 J = (1/4.184) cal

1 pound = 453.592 grams

⇒1 g = (1/453.592) pounds

Now,

[tex]41300\ \text{Joules per gram}=\dfrac{41300\ \text{Joules}}{\text{gram}}\\\\=41300\times \dfrac{\dfrac{1}{4.184}\ \text{calories}}{\dfrac{1}{453.592}\ \text{gram}}\\\\=4477381.7\ \text{calories/pound}[/tex]

Hence, 41,300 Joules/gram = 4477381.7 calories/pound.

Answer:

According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges

Answer:

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

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

From the question

mass = 12 g

density = 19.30 g/mL

We have

[tex]volume = \frac{12}{19.30} \\ = 0.62176165...[/tex]

We have the final answer as

Answer:

Sandy soil

Explanation:

Sandy soil has the greatest permeability of all soil types. It has a high amount of pore space and grain size.

Permeability is the ability of fluids to pass between the grains of a substance, here soil. It is usually a function of the size of the pore spaces and the grain size.

Permeability is very important for determining the quality of soils.

Because the protons = the electrons so the atom will have 56 electrons.

This atom would have 56 electrons.

Atomic Structure:

So, it is given that;

Number of protons=56

Number of neutrons=58

Thus, number of electrons=56 (since, the number of protons and number of electrons are same)

The measurement is precise and accurate

Explanation:

The accuracy of a measurement of length is often indicated by how "precisely" the length measurement can be read depending on the type of measuring instrument used scale.

Looking at the measurement, we can see that the values lie between ±0.1 from the expected values hence it is accurate.

Also, the values differ from each other by ±0.1 hence it the measurements are precise.

Answer:

Accuracy:

5.5 = 98.15%

5.3 = 98.15%

5.4 = 100 %

Precision:

5.5 ± 0.14

5.3 ± 0.14

5.4 ± 0.14

Explanation:

Accuracy is determined using; 100% - % error

% error = absolute error/actual value * 100%

5.5 - 5.4/5.4 * 100% = 1.85%

accuracy = 100 % - 1.85 % = 98.15%

5.3 - 5.4/5.4 * 100 5 = 1.85%

accuracy = 100 % - 1.85 % = 98.15%

5.4 - 5.4/5.4 * 100  % = 0 %

accuracy = 100 % - 0% = 100%

Precision is determined by obtaining the standard deviation of the mean;

s = √{∑(|x - m|)²/(n - 1)}

where x is the value, m is mean of values , n is number of values

mean = (5.5 + 5.3 + 5.4) / 3 = 5.4

deviations from mean, (x - m) are as follows;

|5.5 - 5.4| = 0.1

|5.3 - 5.4| = 0.1

|5.4 - 5.4| = 0

∑(x - m)² = (0.1 + 0.1 + 0) ²= (0.2)² = 0.04

(n - 1) = 3 - 1 = 2

s = √(0.04/2)

s = ± 0.14

Therefore, the precision of each measurement is as follows;

5.5 ± 0.14

5.3 ± 0.14

5.4 ± 0.14

Creativity

Skepticism

Reasoning

Explanation:

Scientists must see a creative way to solve problems in the world. Scientists must also be skeptic about what is said, because if they were not, no one would disagree and the problems would never be solved. Reasoning is a must, as reasoning is involved in the scientific process and writing conclusions to their studies.

Explanation:

Gold is a chemical element and it is the element 79 on the periodic table. Thus, it has an atomic number of 79. The chemical symbol for Gold is Au, it is chemically classified as a transition metal and as a solid at room temperature.

Generally, the chemical element Gold is known to be malleable, ductile and a good conductor of electricity and heat. Also, it is a non-toxic chemical element with a beautiful lustrous sheen.

Gold atoms can be identified based on the number of protons (79) because it represent its atomic number, which is what is used to differentiate an atom of an element from the atom of another chemical element.

P = 11.133 atm (purple)

T = -236.733 °C(yellow)

n = 0.174 mol(red)

Some of the laws regarding gas, can apply to ideal gas (volume expansion does not occur when the gas is heated),:  

So that the three laws can be combined into a single gas equation, the ideal gas equation  

In general, the gas equation can be written  

[tex]\large {\boxed {\bold {PV = nRT}}}[/tex]

where  

P = pressure, atm  

V = volume, liter  

n = number of moles  

R = gas constant = 0.08206 L.atm / mol K  

T = temperature, Kelvin  

To choose the formula used, we refer to the data provided

Because the data provided are temperature, pressure, volume and moles, than we use the formula PV = nRT

T= 10 +273.15 = 373.15 K

V=5.5 L

n=2 mol

[tex]\tt P=\dfrac{nRT}{V}\\\\P=\dfrac{2\times 0.08205\times 373.15}{5.5}\\\\P=11.133~atm[/tex]

V=8.3 L

P=1.8 atm

n=5 mol

[tex]\tt T=\dfrac{PV}{nR}\\\\T=\dfrac{1.8\times 8.3}{5\times 0.08205}\\\\T=36.42~K=-236.733^oC[/tex]

T = 12 + 273.15 = 285.15 K

V=3.4 L

P=1.2 atm

[tex]\tt n=\dfrac{PV}{RT}\\\\n=\dfrac{1.2\times 3.4}{0.08205\times 285.15}\\\\n=0.174~mol[/tex]
