When acceleration is held constant and objects of different mass are observed,are mass and force directly proportional or inversely proportional? explain.

Yes. When two things are directly prortional, that means that as one increases, the other increases at the same rate. So, say you have a 2kg object at an acceleration of 2m/s^2. The force would be 4N. If you have a 3kg object at an acceleration of 2m/s^2, the force would be 6N. If two things are inversely proportional, that means that as one thing increases the other decreases at the same rate. A good example of this is in a chemical reaction. If you increase the surface area of the reactants, the reaction time decreases. They are inversely proportional.

The correct answer is D :Linear

Explanation:

Talking about molecular geometry and arrangement of atoms, liner geometry and trigonal bipyramidal arrangement of atoms would have 3 lone pairs and 2 no. of bond pairs.

For example, in ICl2 and XeF2, the central molecule has 3 lone pairs, and it shows sp3d hybridization.

In trigonal bipyramidal arrangement, orbitals have trigonal bipyramidal structure. It has three-atom molecules which have a linear shape and the orbitals on the equator contain three lone pairs each.
