Answer to Question #8085 in Physical Chemistry for DAVID
Question #8085
International computer communications are carried by optical fibres,laid along the ocean floor. If one strand of optical fibre weighs 0.00119Ib/m.What is the total mass (in Kg) of a cable made of six strands of optical fibre,each long enough to link New Yorkand Paris(8850km).
Expert's answer
The total length of optical fibre is
L = 8850 km * 6 = 53100 km
one strand of optical fibre weighs 0.00119 lb/m = 0.0005398 kg/m = 0.5398 kg/km
The total mass of the cable is
m = 0.5398 kg/km * 53100 km = 28663 kg
Answer: The total mass of the cable is 28663 kg
L = 8850 km * 6 = 53100 km
one strand of optical fibre weighs 0.00119 lb/m = 0.0005398 kg/m = 0.5398 kg/km
The total mass of the cable is
m = 0.5398 kg/km * 53100 km = 28663 kg
Answer: The total mass of the cable is 28663 kg
