Why do a guitar and a piano sound different playing the exact same note? 🎻🎹 In Question 48 of the 2026 SW Mock, we dive back into wave mechanics to find what determines the quality (or timbre) of a sound note produced by a vibrating string. It's not just about how loud it is or how high the pitch is—it's about the unique flavor of the sound! Let's lock in this wave theory mark with iPrep GCE Academy! ✍️📚

Is it a compound or a mixture? 🧪🌬️ In Question 47 of the 2026 SW Mock, we shift our focus to fundamental chemistry. We need to identify which of the given options is a mixture rather than a chemically bonded compound. Knowing the difference between how substances combine is a guaranteed way to secure easy marks on your GCE! Let's clear up the confusion with iPrep GCE Academy. ✍️📚

Why do massive ships stay afloat? 🚢🌊 In Question 45 of the 2026 SW Mock, we analyze the essential physics characteristic of a floating object. When an object sits stably on a fluid surface, there is a perfect equilibrium between the downward pull of gravity and the upward push of buoyancy. Let's break down this mechanics milestone with iPrep GCE Academy! ✍️📚
