Answer:

Carbon-14

Explanation:

Carbon dating is also known as radiocarbon dating. Carbon dating is a technique used in the determination of of age(s) of an object. It has been proved that carbon dating is efficient for dating archaeological specimens and fossils. Carbon dating method was developed by Willard Libby(A physicist).

Carbon-14 is an isotope of of carbon. Carbon-14 is radioactive. Carbon-14 is very important in many aspect both medically( to detect ulcer causing bacteria) and in the determination of age of an object. It is also used in radio labelling.

All living things maintain certain amount of carbon-14 while still alive, but when living things die, the amount of carbon-14 decreases exponentially. Carbon-14 is produced by cosmic radiation in the atmosphere.

What attractive force draws in surrounding electrons for chemical bonds?
Dmitrij [34]

The formation of chemical bonds occurs due to the attractive forces between oppositely charged ions (ionic bonds) or by sharing of electrons (covalent bonds).

An atom having tendency of attracting a shared pair of electrons towards itself and this chemical property is said to Electronegativity .

Thus, the attractive forces which draws in surrounding electrons for chemical bonds is electronegativity.

If u (x) = negative 2 x squared and v (x) = StartFraction 1 Over x EndFraction, what is the range of (u circle ma poottay
KonstantinChe [14]
The range is negative numbers.
The interval for the range is .
***You might want to look at your functions again because I don't see a choice that matches.
Step-by-step explanation:
Given functions:


We are asked to find the range of .
I'm also going to look at the domain just to see if this possibly might change my range .
is the inner function. So we will consider the domain of that function first.
You only have to worry about division by zero for the function .
Since we are dividing by , we don't want to be zero.
So far the domain is all real numbers except .
Now let's move out.
exists for all numbers, . So we didn't want to include from before.
Now let's put it together:







So the domain is still all real numbers except at since we cannot divide by 0 and is 0 when .
with .
is positive for all numbers except .
So is negative for all numbers since negative divided by positive is negative.
So the range is only negative numbers.
Let's also look at the inverse:

Multiply both sides by :

Divide both sides by :

Take the square root of both sides:
.
So can't be 0 and it also can't be positive because the inside of the square root will be negative (since negative divided by positive results in negative).

Can someone provide me with 5 different sentences describing what the boundry type Divergent - Mid-Ocean Ridge is? 10 POINTS!!
Lorico [155]

Answer:

The massive mid-ocean ridge system is a continuous range of underwater volcanoes that wraps around the globe like seams on a baseball, stretching nearly 65,000 kilometers (40,390 miles).

The majority of the system is underwater, with an average water depth to the top of the ridge of 2,500 meters (8,200 feet).

Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart.

As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.

The speed of spreading affects the shape of a ridge – slower spreading rates result in steep, irregular topography while faster spreading rates produce much wider profiles and more gentle slopes.

tell me if this is wrong please
