Answer:
1.MISCIBLE LIQUIDS are those liquids which mix with each other. Alcohol and water are miscible liquids because they mix together in all proportions and form a single layer on mixing. A mixture of miscible liquids is separated by the process of fractional distillation.
Mixtures of liquids can be separated according to their properties. The technique used depends on whether the liquids dissolve in each other, and so are miscible, or if they are immiscible. Fractional distillation is a technique used to separate liquids according to their boiling points.
The two liquids are now separate. Miscible liquids are harder to separate as they dissolve in each other. Miscible liquids are often separated using fractional distillation. This is possible as miscible liquids have different boiling points.
2.Chromatography has various applications. It is used for the separation of different colors of ink. It is also used to identify and separate the preservatives and additives added in the food items. It is also used in DNA fingerprinting and bioinformatics.
3.Separating funnel is used for separating a mixture of immiscible liquid.
4.Hand-picking
Magnetic separation
5.Odometer, or odograph, is a device that measures the distance traveled by an automobile based on the perimeter of the wheel as the wheel rotates.
6.Uniform motion refers only to speed of the object. Speed is described by distance traveled by an object with time. Uniform motion i.e. speed conveys no information regarding the direction of the object.
If object continues to move in fixed direction, then path will look like the straight line. Otherwise with varying direction & uniform motion, there could be various paths like straight line, zigzag line, circle, curve and many more.
7.The SI unit of acceleration is the metre per second squared (m s−2); or "metre per second per second", as the velocity in metres per second changes by the acceleration value, every second.
8.The SI unit of velocity is meter per second (m/s). Alternatively, the velocity magnitude can also be expressed in centimetre per second (cm/s).
