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.

Explanation
√2 cannot be written as a ratio of two integers , so it is an irrational number. Its decimal form is non-terminating and non-repeating (≈ 1.414...).

Explanation
Let's compare the fractions to 0.5 : 1/2 = 0.5 (exact match)

Explanation
Heat is a form of energy , specifically thermal energy , which is transferred from one body to another due to a temperature difference. It is a type of kinetic energy , where the particles of a substance vibrate or move rapidly, generating heat.

Explanation
The pH of pure water (H20) is 7 at 25 °C pH  stands  for " Potential Hydrogen" while Blood is  normally slightly basic,  with a  normal pH  range of about  7.35 to 7.45.
