Answer:

carbon 14 is widely used in paleontology to know the age of objects.

Explanation:

Carbon is a fundamental part of all living beings, this element has two stable isotopes carbon 12 and carbon 13, the first being with an abundance of 98.9% and the other with an abundance of 1.1%, in addition to these there are some radioactive isotopes, that is, they decompose over time. One of the isotopes carbon 14 has a half-life of 5730 years.

 The production of carbon 14 occurs naturally for cosmic radiation with nitrogen from the air, at a constant rate, which is why absorbed by living things with air and integrated into their system, when living beings die they stop absorbing this carbon 14 and the disintegration process begins. Therefore, by analyzing the amount of carbon 14 left in the sample, we can know when it died and infer how much time the sample had.

This procedure is called carbon dating 14, which is widely used in paleontology to know the age of objects.

which process was found after wegeners time, helped scientists find out how the continents actually move.
Genrish500 [490]
I don't quite know what you're asking so I'll just go on a rant :) Wegener created and supported the continental drift theory, which stated that all of the continents once formed a super continent called Pangea. No one at the time believed in the theory though so he spent the rest of his life trying to find evidence to prove it. However, after he died scientists began to find information that supported his theory. When scientists began to study Earth's surface and the layers below, the theory of the tectonic plates was formed. This theory stated that Earth's crust, the lithosphere, was divided into twelve moving plates. This theory did in fact prove that Wegener's theory was correct. Another theory that proved Wegener's theory to be true was the process of Sea Floor Spreading. This theory stated that at divergent plate boundaries, new ocean floor was being created and the old was being pushed away from the boundary, the old sea floor would then be pushed to deep sea trenches created by convergent plate boundaries and essentially recycled back into the Earth. I hope this helped, sorry it is so long :)

Newton’s second law of motion addresses the relationship between what two variables that influence the force on a body?
Helen [10]

Answer:

A. Mass and acceleration

Explanation:

  • According to Newton's second law of motion, the resultant force is directly proportional to the rate of change in momentum
  • Therefore; F = ma , where F is the resultant force, m is the mass, and a is the acceleration of the body.
  • <u>Resultant force depends on the acceleration and the mass of a body in motion, an increase in acceleration causes a corresponding increase in resultant force.</u> A body with higher mass will have a larger strong force if the acceleration is kept constant.

Dimension for electric charge
Artemon [7]

Answer:

AT

Explanation:

Dimensions of current = A

Dimensions of time = T

Current = Charge / time

Therefore Charge = Current × time

                 [Charge] = [Current] × [time]

                                 = AT
