3 0

Answer:

The Cambrian period, which began roughly 541 million years ago, represented the start of the Phanerozoic Eon (we are still in this eon today!). Despite the fact that this period of times makes up nearly 7/8 of the Sarah's history, little is known about the beginning of this period due to the fact that Precambrian rocks are metamorphosed (destroying their origin) or heavily eroded.

Most still haven't even been discovered.

Which of the following is a statement of positive economics?
Ugo [173]

Answer:

a. If the overall unemployment rate is 6 percent, teenage unemployment rates will exceed 12 percent.

Explanation:

Positive economics refers to the description of facts and information related to the economic situation of a country or region. It simply means explaining the facts and reality that is proven by theoretical work as well. It highlights the cause and effect relationships between different economic phenomenon. Here, the statement that if the overall unemployment rate is 6 percent, teenage unemployment rates will exceed 12 percent fulfills this criteria as it presents a simple and well-known fact that teenage unemployment rates are usually higher than the overall unemployment rate and can be double. This is because of a lack of skill set and experience at the youth level as compared to older age groups.

a 62 kg wave boarder is being pulled by a boat with a force of 124N. What is the acceleration of the wave boarder
vfiekz [6]

Answer:

Acceleration = 2m/s^2

Explanation:

Given

Force = 124N

Mass = 62\ kg

Required

Determine the acceleration

This will be calculated using force formula:

Force = Mass * Acceleration

Substitute values for Force and Mass

124N = 62kg * Acceleration

Divide both sides by 62kg

Acceleration = \frac{124N}{62kg}

Acceleration = 2m/s^2

<em>Hence, the wave boarder accelerates at </em>2m/s^2<em></em>
