Answer:There are numerous reasons why soils differ regionally. The most influential factors include the parent material (the rocks from which the soil has come), the climate and terrain of the region, as well as the type of plant life and vegetation present, and, of course, human influence.

The best way to complete the second sentence such that it resembles the one given is "You <u>must have </u>left your phone in the restaurant."
<h3>Reason for using "must have"</h3>
- Using the phrase, "almost certain" infers that a person has little doubt that something has happened.
- The phrase, "must have" also infers little doubt and high probability.
The best phrase to fit in the second sentence that would both be grammatically correct and convey the same meaning, is therefore "must have."
In conclusion, the answer is "must have."

The acceleration of the pendulum mass D is; r"_d = [x''(t) + lθ'' cos θ - lθ'² sin θ]i - l[θ'' sin θ - θ'² cos θ]j
<h3>What is Kinematics of particles?</h3>
Kinematics is the study of the geometry of motion of particles, rigid bodies, etc., disregarding the forces associated with these motions. However, Kinematics of a particle is the motion of a point in space.
From the sample problem, we can solve it using the (x, y, z) coordinate system to get;
r_c = x(t) i
r_d = [x(t) + l sin θ]i + l cos θ j
Finding the first derivative of r_d gives velocity as;
r'_d = [x'(t) + lθ' cos θ]i - lθ' sin θ j
Taking the second derivative of r_d gives the acceleration as;
r"_d = [x''(t) + lθ'' cos θ - lθ'² sin θ]i - l[θ'' sin θ - θ'² cos θ]j
A sample problem of kinematics of particles is;
A block C slides along the horizontal rod, while a pendulum attached to the block can swing in the vertical plane. Find the acceleration of
the pendulum mass D.

Answer:Mass =
no. of molecules / 6.023 * 10^ 23 * Molar mass
Explanation:
Molar mass of CO2 = 44g/mol1.5⋅10256.023⋅1023 = 51.5 moles of CO2 51.5⋅44g/mol=2266grams
