Answer:

F= 1.334x10^-8N

Explanation:.

<em>F(AB)=100G/(50x10^-2)^2   </em>

<em>F(CB)=150G/(50x10^-2)^2</em>

<em>F(net)=F(AB)-F(CB)  </em>

Note that, distance should be in meters so convert it into meter or directly use its meter value (50x10^-2m)

Substitude the value of G=6.67x10^-11Nm^2/kg^2 into the equations and the do the calculations you will obtain the answer.

One student is studying three rock samples, Rock 1, Rock 2, and Rock 3. The characteristics of the three rocks are listed below.
melamori03 [73]
To answer this question, we will refer to the attached diagram which represents the complete rock cycle.

Rock 1:
Formed when rock 2 and rock 3 were subjected to intense heat and pressure inside the earth.
Referring to the diagram, we will find that heat and pressure are the factors required to form metamorphic rocks
Therefore, rock 1 is metamorphic

Rock 2:
Formed when rock 1 and rock 3 were broken down into mineral (sediments) which accumulate and are subjected to pressure.
Referring to the diagram, we will find that this description would lead to the formation of sedimentary rocks.
Therefore, rock 2 is a sedimentary rock.

Rock 3:
Formed when rock 1 and rock 2 were buried inside the earth and melted because of heat and magma.
Referring to the diagram, we would find that melting then cooling of magma would lead to formation of igneous rock.
Therefore, rock 3 is igneous rock.

Based on the above, the correct choice would be:
Rock 1: Metamorphic
Rock 2: Sedimentary
Rock 3: Igneous

How physical properties are important for identifying unknown substances
dmitriy555 [2]

Answer:

Every characteristic property is unique to one given substance. Scientists use characteristic properties to identify an unknown substance. Characteristic properties are used because the sample size and the shape of the substance does not matter.

Explanation:

A characteristic property is a chemical or physical property that helps identify and classify substances. The characteristic properties of a substance are always the same whether the sample being observed is large or small. Examples of characteristic properties include freezing/melting point, boiling/condensing point, density, viscosity and solubility.
