Explanation:

Density

The density of an object of mass m and volume V is given by:

[tex]\displaystyle d=\frac{m}{V}[/tex]

We are given the following densities:

Gold: 19.3 gr/cm3

Silver: 10.5 gr/cm3

With the data provided in the table, we can confirm which of the three columns corresponds to gold, silver, or a mix of both.

Calculating the first density: m1=1,930 gr, V1=100 cm3

[tex]\displaystyle d1=\frac{m1}{V1}[/tex]

[tex]\displaystyle d1=\frac{1,930}{100}[/tex]

[tex]d1=19.3\ gr/cm^3[/tex]

This crown is made of gold

Calculating the second density: m2=1,930 gr, V2=184 cm3

[tex]\displaystyle d2=\frac{m2}{V2}[/tex]

[tex]\displaystyle d2=\frac{1,930}{184}[/tex]

[tex]d2\approx 10.5\ gr/cm3[/tex]

This crown is made of silver

Calculating the last density: m3=1,930 gr, V3=150 cm3

[tex]\displaystyle d3=\frac{m3}{V3}[/tex]

[tex]\displaystyle d3=\frac{1,930}{150}[/tex]

[tex]d3\approx 12.9 gr/cm^3[/tex]

Since the value of the density is between gold and silver, this crown is a mixture.

How to calculate weight on
mars?

Answers

it takes the weight of an object on earth and converts it to Martian weight, the formula is Weight on Mars= (Weight on Earth/9.81m/s2) * 3.711m/s2. To find the Martian weight, we divide the weight on earth by the earth's force of gravity, which is 9.81m/s2. This calculates the mass of the object. Once we have the object's mass, we can find the weight by multiplying it by the gravitational force, which it is subject to. Being that Mars has a gravitational force of 3.711m/s2, we multiply the object's mass by this quanitity to calculate an object's weight on mars.

So an object or person on Mars would weigh 37.83% its weight on earth. Therefore, a person would be much lighter on mars. Conversely, a person is 62.17% heavier on earth than on Mars.

Which list of atomic model descriptions represents

the order of historical development from the earliest

to most recent?

Explanation:

3

Atomic models have been proposed throughout history describing the possible arrangements of different particles inside the atoms.

The very first model for atom was given by Dalton known as the solid sphere model that was an indivisible hard sphere.The model given by Rutherford that was known as nuclear model  mostly included empty space.The model given by Shrodinger showed electron shells as being outside the central nucleus.

Thus, the correct order of atom model is B C A. Hence, the correct answer is option C.

6. A) Silicon, commonly used in electronic devices, is classified as a semiconductor

7. B) Electrons from your hair jump to the balloon, causing it to become negatively charged on one side.

Explanation:

7. The balloon “steals” electrons from your hair, which causes one side of the balloon to become negatively charged. Since your hair lost electrons, it now has a partial positive charge. Opposite charges of static electric attract, causing them to stick together.

6. For a material to be considered a semiconductor, it must have a resistance to electric current that's too high to be considered a conductor but too low to be considered an insulator. Three common semiconductors used in electronic devices are silicon, germanium, and selenium.

5. If three components are arranged to form a parallel circuit, and the individual resistance of these components are r1, r2, and r3 respectively, the formula for finding the total resistance R is: 1/R= 1/r1 + 1/r2 + 1/r3.

When you are standing in a subway train and the train suddenly stops but your body continues to move forward. Which one of Newton's laws is this?
1st law
2nd law
3rd law
4th law

Answers

Answer:

A. 1st law.

Explanation:

Newton's first law of motion states that, an object or body will continue to be at rest or experience a uniform motion in a straight line at constant speed provided there's no action of an external force. Thus, unless compelled to change its state by an external force, a body will continue to be at rest or experience a uniform motion in a straight line.

The Newton's first law of motion is also known as the law of inertia; which is the tendency of a body to be at rest unless acted upon by an external force.

In this scenario, you are standing in a subway train and the train suddenly stops but your body continues to move forward. This is in accordance with Newton's first law of motion.

Hence, the sudden stoppage of the train generates a force which acts on the body thereby causing the passenger to tip or move forward.
