please can anyone answer me pls ​

Answer 1

Match column A and column B accordingly:

Column A ColumnB

1. Length of an

object d. graph paper

2. SI unit of mass f.Kilogram

3. SI unit of time g. Second

4. Measurement

of body c. metre scale

temperature

5. Area of a

rectangle. e. length × breadth

6. Time interval. a.stopwatch

7. Measurement

of mass. h. digital balance

of gold

8. Length of a

curved b. Thread & Ruler

Explanation:

•Length of an object can be found by use of graph paper.

So, 1. - (b)

•SI Unit of Mass is kilogram. It shown as "kg".

So, 2. - (f)

•SI Unit of Time is Second. It shown as "s".

So, 3 - (g)

•For Measurement of body temperature metre scale can be used. Its also called as "thermometer".

So, 4 - (c)

•Area of Rectangle can be measured by lenght× width(breadth).it is formula of area of Rectangle.

So, 5 - (e)

•To observed Time interval we can use stopwatch.stoptwatch shown total time shown on particular process.

So, 6 - (a)

•Measurement of mass of gold can be measured by digital balance. It also called digital scale.

So, 7. - (h)

• length of curved object can be measured by thread and ruler. It is the one type of curved measurements scale.

So, 8. - (b)
