← A particle moves along the x-axis with x = 5 sin(π t + π/3), where x is in centimetres and t in seconds. Its period, its position at t = 0, and its largest speed areA parallel-plate capacitor has plates of area 0.01 m², 2 mm apart. A slab of dielectric constant 4 and thickness 1 mm, as large as the plates, is placed between them. Take ε₀ = 8.85 × 10⁻¹² F/m. The capacitance is closest to →
