CHEMISTRY
A solution is defined as a:
A .
Homogeneous mixture of two or more substances
B .
Heterogeneous mixture of two or more substances
C .
Homogeneous mixture of liquid and solid components only
D .
Homogeneous mixture consisting of water as one of the components
A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase.
A solution consists of a solute and a solvent.
The solute is the substance that is dissolved in the solvent.
For example, in a saline solution, salt is the solute dissolved in water as the solvent.
Answer: A and B
Explanation: If you imagine it to be a coordinate plane. Then horizontal axis is x-axis pointing towards north. Now you draw an angle of 30 degrees with base line as x-axis and common vertex as origin. Now the ray passing through the coordinate plane indicate different displacement at different points but indicating directions towards north-east. Therefore you can mark displacements of 2m and 5m on the same line. Thus (a) and (b) lie on the same straight line. But the other pairs differs in angles as well as direction. Just remember that the direction and angle should be same.
