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.

A 1,400 kg car accelerates from rest to 30 m/s in 6.0 seconds. what is the net force on the car?
Allushta [10]
So your finding acceleration first which is 30m/s divides by 6 seconds equals 5m/s^s and then multiply that by 1,400 kg and you have net force which is 7,000N

What is the mass of a crate if a net force of 12 N gives the crate an acceleration of 0.20 m/s2?
Veseljchak [2.6K]
A :-) for this question , we should apply
F = ma
Given - F = 12 N
a = 0.20 m/s^2
Solution -
F = ma
12 = m x 0.20
m = 12 by 0.20
m = 60 kg

.:. The mass is 60 kg.

A river flows at 2m/s. The velocity of a ferry relative to the shore is 4m /s at right angle to the current. What is the velocit
monitta

The velocity of the ferry relative to the current is 4.5 m/s.

<h3>Relative velocity</h3>
  • Relative velocity is the velocity of a body as observed from the reference point of another body either stationary or in motion.

Since the river is flowing parallel to the shore and the ferry is moving perpendicular to the shore, their velocities are at right angles to each other.

The two velocities form a right angled-triangle of sides 2, 4 and a hypotenuse which gives the relative velocity of the ferry to the current.

Using Pythagoras rule:

  • c² = a² + b²
  • Let c be the hypotenuse
  • a =  velocity of the ferry, and
  • b = the velocity of the current, and

c² = 4² + 2²

c² = 16 + 4

c = 20

c = √20

c = 4.47 m/s

c ≈ 4.5 m/s

Therefore, the velocity of the ferry relative to the current is 4.5 m/s.
