Well to find the answer for force, the formula is mass X acceleration.
So, 20m/s² X 0.5kg = 10kg-m/s².
But, because we measure force in Newtons, we have to change the units (kg/m/s²) to Newtons.
1N (newton) equals to 1kg-m/s² and because we had 10, your answer is
10N
Osteocytes is a bone cell formed when an osteoblast becomes embedded in the matrix it has secreted. So it would be that osteocytes secrete the matrix of Hanoverian canal.
It primarily occurs in the leaves
