The primary product of nuclear fusion reactions in stars is helium, formed from the fusion of hydrogen nuclei.

The primary product of nuclear fusion in stars like the Sun is helium, formed from the fusion of hydrogen nuclei.

A demodulator converts the modulated signal back to its original form.

A modulator converts digital signals to analog for transmission.

Modulation allows signals to be transmitted over long distances by shifting the frequency of the signal to a higher range, making it suitable for transmission through various media.

The formation of droplets is primarily due to surface tension, which minimizes the surface area of the liquid.

Higher molecular weight leads to increased intermolecular forces, resulting in higher viscosity.

Diffraction occurs due to the wave nature of light, allowing it to bend around obstacles and spread out.

Diffraction occurs due to the wave nature of light, allowing it to bend around obstacles.

Electric motors operate based on the Lorentz force, which acts on current-carrying conductors in a magnetic field, causing rotation.

Capillarity is primarily caused by surface tension, which allows liquids to rise or fall in narrow spaces against gravity.

Insulation is used primarily to prevent conduction of heat, thereby maintaining the desired temperature inside buildings.

An unstable nucleus with too many protons typically undergoes alpha decay, where it emits an alpha particle (2 protons and 2 neutrons) to become more stable.

Uranium-238 primarily emits alpha radiation during its decay process.

During alpha decay, an alpha particle, which is a helium nucleus (2 protons and 2 neutrons), is emitted.

The primary use of a Wheatstone bridge is to measure unknown resistances by balancing it against known resistances.

Nuclear fission is primarily used in power plants to generate heat, which is then converted into electricity.

Nuclear fission is primarily used for nuclear power generation.

The primary use of nuclear reactors is to generate electricity through controlled nuclear fission.

Polarizers are primarily used in photography to reduce glare from reflective surfaces.

Radioactive isotopes are primarily used in medicine for diagnostic imaging and treatment.

The principal quantum number (n) corresponds to the shell number. For the 4th shell, n=4.

The principal quantum number (n) indicates the energy level of an electron. For a 3p orbital, n = 3.

The principal quantum number (n) indicates the energy level of an electron. For the 4s orbital, n = 4.

The principle behind a lever is mechanical advantage, which allows a smaller force to lift a larger load.

A potentiometer measures voltage by balancing it against a known voltage, allowing for accurate voltage measurements without drawing current from the circuit.

Thermometers work on the principle of expansion of liquid (like mercury) with temperature.

Archimedes' principle states that a body submerged in a fluid experiences a buoyant force equal to the weight of the fluid displaced.

Electromagnetic induction is based on the principle that a changing magnetic field can induce an electric field and vice versa.

Nuclear fission is the process where a heavy nucleus splits into two or more lighter nuclei, releasing energy.
