4 half lives have occurred. Divide 20 ( the number of years it sat out ) by 5 (it’s half life). To find the remaining amount, divide the 300g by 2 four times, since that’s the amount of half lives that occurred:
300/2 = 150 (1 half life)
150/2 = 75 (2 half lives)
75/2 = 37.5 (3 half lives)
37.5/2 = 18.75 (4 half lives)

There is 18.75 g of Cobalt-60 remaining.

disa [49]

Step-by-step explanation:

पति ऑफिस से घर आया... और खाना खाने बैठा

खाते-खाते उसने अपनी पत्नी से कहा कि

"खाना ठीक नहीं है, कोई टेस्ट नहीं आ रहा है।"

पत्नी चुपचाप उठी, और उसने कॉरपोरेशन मेंं कॉल किया और एम्बुलेंस को बुला ली

और कहा..

"इन्हे टेस्ट नहीं आ रहा है.."

एम्बुलेंस पति को ले गयी और उसे क्वॉरंटाइन कर दिया

अस्पताल में पत्नी ने पति को फोन किया और पूछा: अब आया स्वाद??

यहाँ तक की कहानी सबने सुनी होगी। अब देखिये कहानी में नया मोड़:

उधर पति को पूछा गया कि

"आपके संपर्क में कौन-कौन आया था ?"

पति ने बड़ी ही शांति से कहा..

- मेरी पत्नी

- मेरा ससुर

- मेरी सास

- मेरा साला

- मेरी साली

बस अब ये सब भी अस्पताल के बिस्तर पर बैठे-बैठे पति को घूर रहे हैं!

Moral of the story is

बेजुबान को ज्यादा सताना भी ठीक
