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.

Throwing a football is an example of force because

Answer:

i found this provided by the San Francisco 49ers (found on Khan Academy)

Explanation:

I HOPE THIS HELPS!!!

So, what is a force? A force is a push or a pull exerted on one object from another. Forces make things move. You can make something start or stop when you push or pull an object.

There are many different types of forces in action in football. A player kicking a football is a force that makes the football fly through the air. A quarterback throwing a football is another example of a force that makes the football fly in a game.

When studying the concept of force, we can look to history to find mathematical principles that guide the laws of motion. Sir Isaac Newton was one of the most famous scientists of the 17th century to study the laws of forces and motion. Through careful study of how objects react to various forces, Newton developed the Three Laws of Motion. Below are explanations of each law and how these laws can be applied to football.

A charge of 4.5 × 10-5 C is placed in an electric field with a strength of 2.0 × 104 . If the charge is 0.030 m from the source
snow_tiger [21]

Answer:

The electrical potential energy is 0.027 Joules.

Explanation:

The values from the question are

charge (q) = 4.5 \times 10^{-5} C

Electric Field strength (E) = 2.0 \times 10^{4} N/C

Distance from source (d) = 0.030 m

Now the formula for the electrical potential energy (U) is given by

U = q \times E \times d

So now insert the values to find the answer

U = 4.5 \times 10^{-5} C \times 2.0 \times 10^{4} N/C \times 0.030 m

On further solving

U = 0.027 J
