Question

6. Differentiate between a word scale and a ratio scale. 7. Write the following ratio scales as word scales. 7.1. 1: 10 000 = Icm - 10 OOO 7.2. 1: 30 000 - 1cm=30000 7.3.1: 200 7.4. 1:40 000 8. Describe two differences between large scale and small-sc​

Answer 1

Answer:

Given,

The new value of acceleration due to gravity, 

g′=100g×25=4g

g′=4g

We know that

The variation in the value of acceleration due to gravity is given by:

g′=(h+R)2gR2

4g=(h+R)2gR2

41=(h+R)2R2

Taking square root both side.

21=h+RR

h+R=2R

h=R
