Answer:
Go to explaination for the details of the answer.
Explanation:
In order to determine the lifetime (75 years) chronic daily exposure for each individual, we have to first state the terms of our equation:
CDI = Chronic Daily Intake
C= Chemical concentration
CR= Contact Rate
EFD= Exposure Frequency and Distribution
BW= Body Weight
AT = Average Time.
Having names our variables lets create the equations that will be used to derive our answers.
Please kindly check attachment for details of the answer.
Explanation:
Population inversion is a process of achieving more electrons in the higher energy state than the lower energy state. In order to achieve population inversion, we need to supply energy to the laser medium. The process of supplying energy to the laser medium is called pumping.
The minimum and maximum required footing projections for a concrete footing having a thickness of 8 inches will be 4 inches and 8 inches.
<h3>What is projection?</h3>
It should be noted that footing projections are important for construction purposes

Answer:
The process of generation of force by the high speed that pushes the jet engine forward is based on Newton’s 2 law of motion ?
Explanation:
1, Newton’s first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This postulate is known as the law of inertia.
2,
Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. The momentum of a body is equal to the product of its mass and its velocity. Momentum, like velocity, is a vector quantity, having both magnitude and direction. A force applied to a body can change the magnitude of the momentum, or its direction, or both.For a body whose mass m is constant, it can be written in the form F = ma, where F (force) and a (acceleration)
3, Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.The third law is also known as the law of action and reaction. This law is important in analyzing problems of static equilibrium, where all forces are balanced, but it also applies to bodies in uniform or accelerated motion. The forces it describes are real ones, not mere bookkeeping devices. For example, a book resting on a table applies a downward force equal to its weight on the table. According to the third law, the table applies an equal and opposite force to the book.
