Question

state the magnitude of the following with solution acceleration due to gravity g=9.81m/s​

Answer 1

Explanation:

Order of the magnitude is given by the power of 10 in any quantity.

(a) Acceleration due to gravity,g=9.81m/s

2

So, order is 10

0

(b) Gravitational constant, G=6.67×10

−11

Nm

2

Kg

−1

So, order is 10

−11

(c) The period of rotation of the earth about its own axis is

So, order is 23hrs56mins4secs=86164sec

8.61∗10

4

sec
