Q1. An elevator cable can withstand a maximum tension of 19,500N before breaking. The elevator has a mass of 480 kg and a maximum acceleration of 2.24 m/s2. Engineering safety standards require that the cable tension never exceed two-thirds of the breaking tension. How may 65-kg people can the elevator safely accommodate?

Q2. A double-slit experiment is set up using helium-neon laser (λ = 633 nm). Afterwards a very thin film of glass (n = 1.50) is placed over one of the slits. Afterward, the central point on the screen is occupied by what had been the m = 11 dark fringe. How thick is them glass?
