Yes, a square is a rhombus. But a rhombus is not a square unless the interior angles are at right angles.

We know that, a square is a quadrilateral with all sides equal and all the interior angles are 90 deg i.e, at right angles. 

Whereas

a rhombus is also a quadrilateral with all sides equal but the interior angles are not at right angles. Hence, if the interior angles of a rhombus are all at right angles (90 deg), then it is square.

1. A fixed budget is established for a specific level of activity whereas flexible budget is prepared for various levels of activity.

2. Fixed budget cannot be changed after the period commences, whereas a flexible budget can be changed after the period commence.

3. Fixed budget is more suitable for fixed expenses whereas flexible budget takes both fixed as well as variable expenses in account.

4. Fixed budget includes only fixed costs, whereas a flexible budget includes fixed costs, variable costs and semi variable costs.

5. Fixed budget is mainly used in planning stage whereas flexible budget is used in controlling stage.

When exports are greater than imports, net exports are positive and similarly, when imports are greater than exports, net exports are negative.

The goal of a statement of purpose is to indicate what is expected to be accomplished in doing an experiment.

On the basis of magnetic properties, substances are classified into three groups namely diamagnetic, paramagnetic and ferromagnetic.

As solids diffuse and reorder very slowly under ambient conditions, the net, directionally dependent (anisotropic) magnetic moment can persist. Conversely, liquids and gases freely tumble and reorder: water rearranges every few pico seconds (10^12 times per second).

Hence liquids and gases can never show ferromagnetic properties.
