JEE & NEET Diagnostic Test

💡 Insight: Gravity (g) acts downwards continuously throughout the motion, even when instantaneous velocity reaches zero.

💡 Insight: NH4Cl has covalent bonds between N and H in the ammonium cation (NH4+), and an ionic bond between NH4+ and Cl-.

💡 Insight: log₂(x(x - 2)) = 3 => x² - 2x = 8 => x² - 2x - 8 = 0 => (x - 4)(x + 2) = 0. Since log requires x > 2, x = 4.

💡 Insight: Buoyant force depends on total displaced fluid volume; hollow construction reduces overall bulk density below that of water.

💡 Insight: Mitochondria perform the Krebs cycle and oxidative phosphorylation to produce ATP.
