Darragh's coin has lost 0.164 grams
Step-by-step explanation:
Simple subtraction has to be done to find the amount of weight the coin has lost.
Given
The coin's actual weight = [tex]w_i = 13.715g[/tex]
Coin's weight after circulation = [tex]w_f = 13.551g[/tex]
So, the weight lost will be:
[tex]w = w_i - w_f\\= 13.715-13.551\\=0.164g[/tex]
Hence,
Darragh's coin has lost 0.164 grams
