An 8 N force is applied to a 2 kg object. What is the magnitude of the object's acceleration? A. 0.25 m/s² B. 4 m/s² C. 6 m/s² D

mel-nik [20]

Answer: 4m/s2 (B)

Explanation:

Force = mass × acceleration

Force given is 8N

Mass=2kg

Acceleration =?

Substitute into the formula

F=ma

8=2a

A=8/2

A=4m/s2

Acceleration used is 4m/s2 (B)

Select the electron-domain geometry for a molecule with three bonding domains and one nonbonding domain.

mamaluj [8]

Answer: C) Tetrahedral

Explanation:

The number of electron pairs is 4 that means the hybridization will be $sp^3$ but as there are three bonding domains and one nonbonding domain, thus electronic geometry is tetrahedral and the molecular geometry will be trigonal pyramidal.

Linear electron geometry is possible when number of electron pairs is 2 and the hybridization will be $sp^2$ .

Trigonal planar geometry is possible when number of electron pairs is 3 and the hybridization will be $sp^3$ .

Trigonal bipyramidal geometry is possible when number of electron pairs is 5 and the hybridization will be $sp^3d$ .

Octahedral geometry is possible when number of electron pairs is 6 and the hybridization will be $sp^3d^2$ .
