Answer:

number one use carbon 14

Explanation:

Answer:

A

Explanation:

Carbon-14 testing of organic material such as wood can approximate the age by measuring the radioactive decay rate of the carbon-14 in the wood. From that a baseline for the trees age can be established and the ring patterns can by applied to a time period.

Explanation:

Technology is the application of scientific research and knowledge .

Answer:

Explanation:

3. The word circuit means "go around", therefore a circuit is a pathway or closed path around which electricity (or water) flows.

4. Electrons flowing through a wire can be compared to water flowing through a hose. Once the flow of electrons or water is going, work, is performed.

5. You would get shocked in a bumper car by touching the floor and the ceiling at the same time. This means you are completing the circuit allowing electricity to flow.

6. Electricity from a wall outlet has enough energy to stop your heart.

7. Electricity is the flow of electrons, because electrons move or jump from atom to atom.

8. Materials that allow electrons to move easily from atom to atom are called conductors.

9. Materials that do not allow electrons to flow easily are called insulators.

10. Semi- conductors are materials that are somewhere in between .

11. Voltage is the force or pressure of electricity and is compared to the amount of water pressure in a hose.

12. Current (amps ) is the amount of electricity and is compared to the amount of water in a hose .

13. Watts (power) is the term for work performed by electricity.

Answer:

Mercury is the only one in liquid state at room temperature. It's used in thermometers because it has high coefficient of expansion.  It also has a high boiling point which makes it very suitable to measure higher temperatures. Also, it has a shiny appearance and doesn't stick to the glass surface of glass.

Explanation:

Answer: An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.

Explanation: The parts of a circut bit can easily be found online, but heres a pic i found.

As the shape of a molecule has a lot to do with the polarity of the compound, the molecular structure influences the molecular properties. Polar compounds tend to dissolve in polar compounds, forming solids or liquids with higher boiling and melting points.

A physical property is a property of matter that is unrelated to changes in its chemical composition. Density, color, hardness, melting and boiling points, and electrical conductivity are all examples of physical properties.

In the solid state, the structure determines how individual polymer molecules can orient. As a result, physical properties such as density, crystallinity, melting point, and strength are affected.

Intermolecular forces - forces that attract one molecule to its neighbors - van der Waals attractions or hydrogen bonds - govern physical properties.

Because the intermolecular forces of attraction are relatively weak, molecular substances tend to be gases, liquids, or low melting point solids.

Thus, this way the molecular structure of a material influence its physical properties.

Answer:

s₁ = 240,000 km

Explanation:

The distance between both the focuses f₁ and f₂ will be the sum of distances of the moon from each focus at a given point. Therefore,

s = s₁ + s₂

where,

s = total distance between the focuses = ?

s₁ = distance between f1 and moon = 200,000 km

s₂ = distance between f₂ and moon = 300,000 km

Therefore,

s = 200,000 km + 300,000 km

s = 500,000 km

Now, when the distance from f₂ becomes 260,000 km, then the distance from f₁(planet) will become:

s = s₁ + s₂

500,000 km = s₁ + 260,000 km

s₁ = 500,000 km - 260,000 km

s₁ = 240,000 km

Answer: For #1, 7.3 m/s2.

Explanation: See this wikipedia screenshot for explanation, it's complicated.

Answer:

Explanation:

5x + y = 7

20x - y = -2

    25x = 5

        x = (1/5)

5(1/5) + y = 7

1 + y = 7 .

y = 6

system of equations  5x+y=7, 20x+2=y

is  [tex]x=\frac{1}{5} \\y=6[/tex]

Therefore,

Calculation

[tex]5x+y=7.............(i)\\20x+2=y..........(ii)[/tex]

adding equations (i) and (ii)

⇒[tex]5x+y=7-(20x-y=-2)[/tex]

⇒[tex]25x=5[/tex]

⇒[tex]x=\frac{1}{5}[/tex]

putting the value of x in equation (i), we get

⇒[tex]5[/tex]×[tex]\frac{1}{5}+y=7[/tex]

⇒[tex]y=7-1[/tex]

⇒[tex]y=6[/tex]
