What will happen if we shift the camel from the desert to the polar region ?

Camel is the only domestic animal that can easily survive in desert area. 

But in case, if you shift your camel in the polar region means cold region area, they are not much comfortable to survive in this area as they can survive in desert area.

So here in your mind one question is come, why camel cannot survive in cold area region ?

So first of all you need to know that, all living being on earth is different different living nature and environment, according to their living nature of their body.

Biologically camel not have any type of insulation to prevent body heat from releasing.

But in polar region animals have insulation to prevent body heat from releasing.

So therefore, if we want to shift our camel in polar region, so it is proved very risky for camel heat.

Find the square root of each of the following correct to three decimal places. (i) 2.5 (ii) 0.036 (iii) 6.4 (iv) 0.100

 i) Square root of 2.5 =  1.581

ii) Square root of 0.036 =  0.189

iii) Square root of 6.4 =  2.529

iv) Square root of 0.100 =  0.316

Define Radius of gyration, SI unit, Dimension

Define:- The radius of gyration defined as, the whole mass of the body                is supposed to be concentrated, so as to possess the same                       moment of inertia as that of body about the same axis is                       called as radius of gyration.

SI Unit:- m (metre)

CGS Unit:- cm (centimetre)
