Question1
Chlorine gas (Cl2) can be formed from a solution containing Cl−ions (i.e., from Na+Cl−) by electrolysis. What should be the current throughout an electrolytic cell to produce 1.0 kg of Cl2 gas in 7 hours? The basic charge is 1.602×10−19C, Avogadro’s number is 6.022×10 23, and atomic mass of chlorine is 35.5 g/mol. (Answer in units of A)
Question2
A string under a tension of 53.5 N uses to whirl a rock in a horizontal circle of radius 2.65 m at the speed of 20.7 m/s on frictionless surface. As a string is pulled in, speed of the rock increases. While string is 1.00 m long and the speed of the rock is 53.0 m/s, the string breaks. What is the breaking strength, in Newton’s, of string?
