Magnetic susceptibility of magnesium at 300K of temperature is 1.2times10^(-5) ,the magnetic susceptibility of magnesium at 30 K of temperature will be 1.2times10^(-3) 1.2times10^(-4) 1.2times10^(-5) 1.2times10^(4)

The product of 1.7 xx 10^(4) and 12.5 xx 10^(–6) is expressed in the standard form as k xx 10^(n) . The value of (2k + n) is

(14.96 xx 10^(10)) - (3.84 xx 10^(8)) is expressed in standard form as

Write ‘T’ for true and ‘F’ for false foe each of the following: ( i ) 645 in standard form is 6.45 xx 10^(2). ( ii ) 27000 in standard form is 27 xx 10^(3). ( iii ) (3^(0)+4^(0)+5^(0))=12. ( iv ) Reciprocal of 5^(6) is 6^(5) . ( v ) If 5^(-1) xx x =8^(-1), then x =frac(8)(5).
