Explanation:
The speed of sound in the air increases 0.6 m / s for every 1 ° C increase in temperature. An approximate speed can be calculated using the following empirical formula:
Where:
A more exact equation, usually referred to as adiabatic velocity of sound, is given by the following formula:
Where:
Hence:
Now, the Mach number at which an aircraft is flying can be calculated by:
Where:
Therefore:
Answer / Explanation:
The result of the Training and Exercise Planning Workshop (TEPW) is to set the foundation for the strategy and pattern for a proposed exercise program. The TEPW purpose is to engage elected and selected officials in identifying exercise program priorities and planning a schedule of training and exercise events to meet those priorities.
An essential factor for the exercise management process is to create a collaborative environment where a whole community stakeholders can engage in a forum to discuss and coordinate training and exercise activities across local organizations to maximize the use of available resources and prevent duplication of effort.

Centripetal force is modeled by the equation:
F = MV^2/R
where
F = force
M = Mass
V = Velocity
R = Radius
I will assume the shark is swimming in a circle with a radius of 14 m / 2 = 7 m. The actual radius will be smaller, but I'll assume that the question is simply poorly worded. So we need to calculate the velocity of the shark. The circumference of the circle is pi*14m = 43.98229715 m. And since velocity is defined as distance over time, we have a velocity of 43.98229715 m / 80 s = 0.549778714 m/s.
Now substitute the known values into the equation for centripetal force.
F = MV^2/R
F = 681 kg * ( 0.549778714 m/s)^2 / 7m
F = 681 kg * 0.302256635 m^2/s^2 / 7m
F = 205.8367683 kg*m^2/s^2 / 7m
F = 29.40525261 kg*m/s^2
F = 29.40525261 N
Rounding to 2 significant figures gives a force of 29 Newtons.</span>
