Explanation The core principle behind a hydrogen bomb is the fusion of light atomic nuclei. Specifically isotopes of hydrogen ( deuterium and tritium ), under extremely high temperatures and pressures.  Explanation Milk is a mixture, not a compound — it contains water, fats, proteins, etc., physically combined. Chalk (CaCO₃), Ammonia (NH₃), and Table Salt (NaCl) are pure compounds with fixed chemical formulas. Explanation Calcium belongs to Group 2 of the periodic table, known as alkaline earth metals. These metals are shiny , somewhat reactive , and include beryllium, magnesium, calcium, strontium, barium, and radium. Explanation Tin has the lowest melting point (~232°C) among. Zinc (~419°C) Gold (~1064°C) Lead (~327°C) Explanation The Sun's energy comes from nuclear fusion , where hydrogen nuclei fuse to form helium , releasing enormous energy. This process occurs in the Sun’s core under extreme temperature and pressure , following the proton-proton chain reaction. Explanation Momentum is given by the formula: p = mv, where m is mass and v is velocity (or speed). It depends on mass and speed , not on acceleration, so momentum is independent of acceleration. Explanation When a car moves at constant velocity, it means there is no acceleration . According to Newton’s First Law , if there’s no acceleration , the net force acting on the object is zero . Explanation In uniform circular motion , instantaneous velocity is tangent to the circular path. Instantaneous acceleration (centripetal) is directed toward the center, making the two vectors perpendicular to each other . Explanation Acceleration is directly caused by a net force acting on an object . It always occurs in the same direction as the net (unbalanced) force applied. Explanation Centripetal force acts perpendicular to the direction of motion, so it does no work. Work = Force × Displacement × cos(θ) ; since θ = 90°, cos(90°) = 0, so Work = 0.
