Question

The R.F of p+ √q is
A. -p-√q
B. p-√q
C. p+(-√q)
D. both b&c
​

Answer 1

Answer:

Step-by-step explanation:

‎• Distance between P and Q = 5cm

‎ ‎ ‎ ‎• Actual distance between them =20km

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎• Relative Distance (R.F.) of map

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎• Scale of the map

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎• R.F. of the map = Distance on map / Distance on ground

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎As we have distance on the ground so, scale of map is 5cm to 20km or 1cm to 4km.

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎Calculating the R.F. of the map...

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎That is,

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎R.F. of the map = Distance on map / Distance on ground

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ Evaluating values...

‎ ‎ ‎ ‎ ‎ ‎ ‎⟹ ‎

‎ ‎ ‎ ‎ ‎ ‎ ‎⟹  

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎Note:–

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎1km = 1,00,000 cm

Understanding the terms:-

• Scale of a map : Maps represent the surface of the earth on a small scale on a piece of paper.

• Representative fraction : A useful and accurate method of representing the scale of a map is by a ratio or fraction called representative fraction.

• Maps : Maps are drawn to represent the earth as a whole or parts of it drawn to scale on a flat surface.
