A
most common source of phosphates in the soil is the weathering of the mineral apatite.
Explanation:
Apatite is a group of phosphate minerals like hydroxylapatite, fluorapatite, and chlorapatite. When apatite rocks weather, they release the phosphate minerals mainly in the form of PO₄ ³⁻ . These minerals become dissolved in water (hydrosphere), where they are readily available to plants and other organisms in the biosphere. The phosphates are taken up and used in biosynthesis. When these organisms die and become buried with sediments, the phosphate gets back to the lithosphere as sedimentary rock.

Answer:
The final velocity of the race car is 27.14 m/s
Explanation:
Given;
initial velocity of the race car, u = 18.5 m/s
acceleration of the race car, a = 2.47 m/s²
distance covered by the race car, s = 79.78 m
Apply the following kinematic equation to determine the final velocity of the race car.
v² = u² + 2as
v² = (18.5)² + 2(2.47)(79.78)
v² = 736.363
v = √736.363
v = 27.14 m/s
Therefore, the final velocity of the racecar is 27.14 m/s

The technology that is involved with an ultrasound technologist include a diagnostic medical somographer and medical imaging technology.
<h3>Who is a ultrasound technologist?</h3>
It should be noted that an ultrasound technologist means an individual who uses specialized equipment to examine the human body.
The technology involves electromagnetic or sound waves as it used high. frequency sound waves to create images of the tissues in the body.
The basic properties of wave are wavelength, time period, frequency, speed and amplitude. The fundamental properties are reflection, refraction, diffraction, and interference.
The things needed for a ultrasound technologist include a degree in diagnostic medical sonography and a medical training in a hospital.
The advantages of this career include the fact that it offers job variety, there's job growth potential, and they earn a decent salary.
