← All Quizzes

← A steel wire is fixed between two rigid supports 0.80 m apart. It is stretched so that its strain is 1.6 × 10⁻³. Steel has a Young's modulus of 2.0 × 10¹¹ Pa and a density of 8000 kg/m³. What is the fundamental frequency of the wire? Give the answer in Hz.Which change leaves the stopping potential of a photocell unchanged? →
