8 0

Question: Which of these is an environmental cost of tar sands extraction? A.Mine collapse

B.Pollution

C.Acid rain

D.Shale deposits

Answer:

The correct answer is B. pollution.

Explanation:

A combination of sand, clay, water and bitumen (hydrocarbon) is named tar sands or oil sands. Bitumen is mined from tar sands and polished it to harvest gasoline and withdrawal of tar sands importantly influence on atmosphere. Once gasoline made from tar sands harvests extra carbon dioxide as compare to outdated oil extraction. The mining of tar sands has improved carbon releases over a period of time. Thus, growth percentage of carbon dioxide reasons pollution.

Edema occurs when____________
Maksim231197 [3]

Answer:

A) areolar tissue soaks up excess fluid in an inflamed area

Explanation:

Areolar tissue is found around blood vessels, muscles, nerve bundles. Edema which is also a part of inflammation occurs when blood capillaries of blood vessels leak the fluid and is soaked by areolar tissue. So excess fluid in these tissue cause swelling of that part.

Edema is one type of defense reaction to the cell injury. With fluid white blood cells and defense proteins move in the area and counter the infectious agent of injury and helps in eliminating the injurious factor. So the correct answer is A.

A performer, seated on a trapeze, is swinging back and forth with a period of 8.90 s. If she stands up, thus raising the center
iren2701 [21]

Answer:

8.800s

Explanation:

When the performer swings, she oscillates in SHM about Lo of the string with time period To = 8.90s.

First, determine the original length Lo, where for a SHM the time period is related to length and the gravitational acceleration by the equation

T = 2π×√(Lo/g)..... (1)

Let's make Lo the subject of the formulae

Lo = gTo^2/4π^2 ..... (2)

Let's put our values into equation (2) to get Lo

Lo = gTo^2/4π^2

= (9.8m/s^2)(8.90s)^2

------------------------------

4π^2

= 19.663m

Second instant, when she rise by 44.0cm, so the length Lo will be reduced by 44.0cm and the final length will be

L = Lo - (0.44m)

= 19.663m - 0.44m

= 19.223m

Now let use the value of L into equation (1) to get the period T after raising

T = 2π×√(L/g)

= 2π×√(19.223m/9.8m/s^2)

= 8.800s

What are the two recognized means of preventing injury during electrical equipment operation?
baherus [9]
Grounding and insulation will be the two most recognized means of preventing injury during an electrical equipment operation. The workers should always place a non-conductive material like plastic around the conductor of electricity. When grounding, there needs to be a direct connection to either a cold water pipe or even metal. Without doing either grounding or insulation, there is a chance of burns, shocks, fire, and in extreme cases death.
