2.) What are some major soil properties and behaviors that are influenced by soil separates?

Answers

Answer and Explanation:

Some of the soil seperates are listed below:

  • Clay
  • Silt
  • Sand

where clay is the smallest and sand is the largest.

Some of the behaviors or properties influenced by soil seperates are listed below:

  • Porous nature of soil or generally called as porosity which can be defined as the total volume of soil with pore spaces volume.
  • Water drainage pattern refer to as soil drainage.
  • Ratio of interlinked pores to the total soil volume(permeability).
  • The intensity and the nature of vegetation in the soil.
  • They affect the geological structure of the soil.

Scientists to determine the location of an earthquake's epicenter they must first determine the distance to the epicentre from all seismograph stations recording the quake.

What is seismograph?

A seismograph, or seismometer, is an instrument used to detect and record seismic waves. Seismic waves are propagating vibrations that carry energy from the source of an earthquake outward in all directions. They travel through the interior of the Earth and can be measured with sensitive detectors called seismographs. Scientists have seismographs set up all over the world to track the movement of the Earth's crust.

Seismic waves are divided into two types: body waves and surface waves. Body waves include P (compressional or primary) waves and S (transverse or secondary) waves. An earthquake radiates P and S waves in all directions and the interaction of the P and S waves with the Earth's surface and shallow structure produces surface waves. Near an earthquake the shaking is large and dominated by shear-waves and short-period surface waves. These are the waves that do the most damage to our buildings, highways, etc. At farther distances the amplitude of the seismic waves decreases as the energy released by the earthquake spreads throughout a larger volume of Earth.

Seismographs record a zig-zag trace that shows the varying amplitude of ground oscillations beneath the instrument.

To figure out just where that earthquake happened, you need to look at your seismogram and you need to know what at least two other seismographs recorded for the same earthquake. You will also need a map of the world, a ruler, a pencil, and a compass for drawing circles on the map.

Two stars that are 109 km apart are viewed by a telescope and found to be separated by an angle of 10-5 radians. The eyepiece of the telescope has a focal length of 1.5 cm and the objective has a focal length of 3 meters.

Answers

Answer:

Distance between star and observer = 2 × km

Explanation:

Step 1

Angular magnification of telescope is given by formula:

             M = - f° ÷ fⁿ

where

M is angular magnification

f° is focal lens of object lens

fⁿ is  focal lens of eyepiece lens

Step 2

      M =  300cm ÷ 1.5 cm

           =  - 200 (-tive sign means image is inverted)

  M =  θⁿ ÷ θ°

   solve for θ°

  θ° =   θⁿ ÷ M

       =   ÷  200

       = 5 × radians

Step 3

now find distance between star and observer

  Adj = opposite ÷ θ°

         =   ÷ 5 ×

         =  2 × km

A graphical representation of the strength of an acid or base​

Answers

The correct answer to this open question is the following.

A graphical representation of the strength of an acid or base​ is the "pH scale."

The pH scale is used to represent the acidic grade of a solution. The ph scale helps us to identify the concentration of hydrogen ions in any solution. The first studies on the subject were developed by Danish scientist Soren Lauritz Sorensen in 1909.

Answer: titration curve

Explanation:

A titration curve is a graphical representation of the pH of a solution during a titration. The figure below shows two different examples of a strong acid-strong base titration curve. On the left is a titration in which the base is added to the acid and so the pH progresses from low to high.

________ is a measurement of displacement on the fault surface.

Answers

Fault slip is a measurement of displacement on the fault surface. The term fault slip comes from fault, which is a rock fracture where the two sides have been displaced relative to each other. 
When faults suddenly slip past one another the result is earthquake. The measurement of fault slip determines the seismic potential of faults.

The total distance around wendy's rectangular-shaped bedroom is 260 feet. The width of the room is 60 feet. What iOS the area of wendy's bedroom use the appropriate unit of measure

Answers

Answer:

Given;

The total distance of the rectangular-shaped bedroom is 260feet.

This also means that the perimeter of the room is 260feet.

The width of the room is 60feet.

Let the perimeter of the bedroom be p = 260feet

The perimeter of a rectangle p = 2 (length + width)

i.e p = 2 (length + width) --------------------- (i)

Substituting p=260 and width=60 in equation (i) gives;

260 = 2 (length + 60)

Dividing both sides by 2 gives

130 = length + 60

Making length the subject of the formula gives;

length = 130 - 60

length = 70feet

Since we have the length=70feet and width=60feet for the bedroom, we can calculate the area as follows:

Area of rectangle(bedroom) = length * breadth

Area = 70 * 60 = 4200

Therefore, the area of Wendy's bedroom is 4200 squarefeet.

This can also be written as 4200

Hope this helps!

Explanation:

I don't know the math equations on how to do it to be honest, but I know you're just looking for the answer.  

60+60=120 260-120=140 140/2=70 70*60=4200

Your answer is 4200ft^2

Why may you be asked whether you are allergic to eggs before receiving a vaccination?

Answers

Some vaccines are made out of egg proteins, which is why it is imperative for those administering them to ask if the patient has an egg allergy. Some vaccines may cause a severe allergic reaction. However, if hives are all the patient gets from eggs, the vaccines are still administered. If they get more than hives, they are closely monitored if given the vaccine.
