The American physical chemist Gilbert Newton Lewis (1875-1946) proposed a unit of time called a jiffy. According to Lewis, 1 jiffy is the time it takes light to travel 1 cm. (c= 2.998 x 10^8 m/s)

Answer:

a) 0.0166 s

b) 3600 jiffys

Explanation:

a) A jiffy is equivalent to a 60th of second:

[tex]1 jiffy=\frac{1}{60 s}=0.016666 s[/tex]

Hence, if a task is performed in [tex]1 jiffy[/tex] this is equivalent to [tex]0.016666 s[/tex]

b) Now, if a minute is equal to 60 seconds, we can make the transformation to jiffys:

[tex]1 min \frac{60 s}{1 min} \frac{1 jiffy}{0.016666 s}=3600.144 jiffys \approx 3600 jiffys[/tex]
