.^(60 m)Co rarr .^(60)Co emits gamma -radiations of wavelength 3 xx 10^(-10) . Assuming each nuclei emits one wavelength, with what mass per mole of two nuclei differ? a. 4.43 xx 10^(-9) g b. 4.43 xx 10^(-4) g c. 4.43 xx 10^(-3) g d. 4.43 g

Assertion: Like light radiation, thermal radiations are also electromagnetic radiation. Reason: The thermal radiations require no medium for propagatio.

alpha, beta and gamma radiations come out of a radioactive substance

Assertion: Between alpha, beta and gamma radiations, penetrating power of gamma -rays is maximum. Reason : Ionising power of gamma -rays is least.
