4. The amount of space occupied by a substance

Accepted Answer

A device used to measure the speed of automobiles:

The speedometer of the automobile measures the speed of an automobile at any instant of time during the motion of an automobile.

Note: A speedometer or a speed meter is a gauge that measures and displays the instantaneous speed of a vehicle. It measures the speed as the distance travelled per hour. It measures the speed in any unit system like $kilometres per hour$ or $miles per hour$ .

A device used to measure distance travelled, commonly fitted in vehicles:

An Odometer meter is a device that is used to measure the distance travelled by a car. Odometer only measures the distance, not displacement. The odometer is used with the speedometer which is a separate device which measures the instantaneous speed of the car.

It is a tube similar to a measuring jar, with a pinch-cock provided at the bottom.

Measuring cylinders, such as burette and pipette are used for laboratory purposes. Burette consists of a narrow glass tube marked in ml and provided with a tap at the lower end. Each ml is divided into ten equal parts. The marking is from top to bottom.

_____ is the mass per unit volume of a substance or object.

The mass per unit volume of a substance is called its density. If $M$ is the mass of an object of volume $V$ , such that $D$ is its density, then $D = \frac{M}{V}$ . In the SI system, mass is measured in kilograms and volume in cubic meters. Therefore, the unit of density in the SI system is $kg m^{- 3}$ .

The amount of space occupied by a substance

Amount of space a matter takes is known as volume. Solids and liquids have a definite volume, but gases do not have a definite volume.

Distance travelled per unit time:

Speed is defined as:- Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.

Or The rate of change of position of an object in any direction is called speed.

The formula of speed is given as $Speed = \frac{Distance}{Time}$ $= s = \frac{d}{t}$

Where, $s =$ Is the speed in metres per second $(m / s)$ , $d =$ Is the distance travelled in metres $(m)$ , $t =$ Is the time taken in seconds $(s)$
