Answer:
It's STERIC NUMBER.
Explanation:
The steric number is the number of shared pairs of electrons on a central atom of a molecule (σ sigma bond) plus the number of lone pairs on the central atom.
Answer:
-10 m/s^2
Explanation:
Acceleration = Change of velocity over time
25/2.5 = 10 m/s^2
Since we are deccelerating here (Going slower) then the number is written as negative
Answer:
![1.34103\times 10^{-7}\ m](https://tex.z-dn.net/?f=1.34103%5Ctimes%2010%5E%7B-7%7D%5C%20m)
Explanation:
F = Shearing force = 420 N
= Initial length = 2.6 cm
d = Diameter = 3.6 cm
r = Radius = ![\frac{d}{2}=\frac{3.6}{2}=1.8\ cm](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7B2%7D%3D%5Cfrac%7B3.6%7D%7B2%7D%3D1.8%5C%20cm)
E = Young's modulus = ![80\times 10^9\ N/m^2](https://tex.z-dn.net/?f=80%5Ctimes%2010%5E9%5C%20N%2Fm%5E2)
A = Area = ![\pi r^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2)
Change in length is given by
![\Delta L=\frac{FL_0}{AE}\\\Rightarrow \\\Rightarrow \Delta L=\frac{420\times 0.026}{\pi 0.018^2\times 80\times 10^9}\\\Rightarrow \Delta L=1.34103\times 10^{-7}\ m](https://tex.z-dn.net/?f=%5CDelta%20L%3D%5Cfrac%7BFL_0%7D%7BAE%7D%5C%5C%5CRightarrow%20%5C%5C%5CRightarrow%20%5CDelta%20L%3D%5Cfrac%7B420%5Ctimes%200.026%7D%7B%5Cpi%200.018%5E2%5Ctimes%2080%5Ctimes%2010%5E9%7D%5C%5C%5CRightarrow%20%5CDelta%20L%3D1.34103%5Ctimes%2010%5E%7B-7%7D%5C%20m)
The shear deformation of the vertebra is ![1.34103\times 10^{-7}\ m](https://tex.z-dn.net/?f=1.34103%5Ctimes%2010%5E%7B-7%7D%5C%20m)
Answer:
10
Explanation:
Each time you want to move up the scale, the number is multiplied by 10. The opposite is true when moving down; you must divide by 10.
