A cobalt specimen emits induced radiation of 75.6 millicurie per second. Convert this disintegration into becquerel.
(one curie = `3.7xx10^(10) Bq`)

Text Solution

Verified by Experts

Cobalt specimen emits induced radiation = 75.6 millicurie per second ( `"1 curie" = 3.7 x 10^(10)` Bq)
So 75.6 millicurie = `75.6 xx 10^(-3) xx 1 "curie"`
`75.6 xx 10^(-3) xx 3.7 xx 10^(10)` Bq
`= 279.72 x 10^(7)`
`= 2.7972 xx 10^(9) "Bq"`
75.6 millicurie per second is equivalent to `2.7972 xx 10^(9) "Bq".`

One end of a rod length 20cm is inserted in a furnace at 800K. The sides of the rod are covered with an insulating material and the other end emits radiation like a blackbody. The temperature of this end is 750K in the steady state. The temperature of the surrounding air is 300K. Assuming radiation to be the only important mode of energy transfer between the surrounding and the open end of the rod, find the thermal conductivity of the rod.
