The semisolid material that supports collagen fibers in the bone matrix is called osteoid , which comprises organic materials that help in bone formation. It is essential for the development of strong bone structure through mineralization. Osteoid plays a pivotal role in maintaining the flexibility and strength of bones. ;
To calculate the number of electrons flowing through a device with a current of 15.0 A for 30 seconds, we find the total charge as Q = 15.0 A × 30 s = 450 C. Knowing that the charge of a single electron is approximately 1.6 × 10^{-19} C, we find that approximately 2.81 × 10^{21} electrons flow through the device.
