Explanation

• Asteroids travel around the Sun in elliptical orbits.
• Most asteroids are found in the Asteroid Belt between Mars and Jupiter.
• Their orbits follow Kepler's Laws of Planetary Motion.
• The shape of the orbit may vary from nearly circular to highly elliptical.
• Asteroids are small rocky bodies that revolve around the Sun.

Explanation

• Navigation satellites are used to identify the location of objects on Earth.
• They provide position, navigation, and timing (PNT) services.
• These satellites help determine the exact location of people, vehicles, ships, and aircraft.
• They are widely used for navigation, mapping, and tracking.
• The most well-known navigation satellite system is GPS (Global Positioning System).

Explanation

• The collective term for all the petals of a flower is called the Corolla.
• The corolla is usually brightly colored to attract pollinators such as insects and birds.
• It is the second whorl of a flower, located inside the calyx.
• Petals help in the process of pollination.

Additional information:

• Calyx → Collective term for sepals
• Androecium → Male reproductive part (Stamens)
• Gynoecium (Pistil) → Female reproductive part (Carpels)

Explanation

• In forging, a slow squeezing process is called Press forging.
• Press forging shapes the metal by applying slow and continuous pressure.
• It produces more accurate shapes and a better surface finish than hammer forging.
• It is commonly used for manufacturing large and strong metal components.
• The process improves the strength and grain structure of the metal.

Explanation

• Poisson’s Ratio (μ or ν) is the ratio of lateral strain to longitudinal strain.
• Formula: ν = Lateral Strain / Longitudinal Strain
• Longitudinal strain occurs in the direction of the applied load.
• Lateral strain occurs perpendicular to the applied load.
• It is a dimensionless quantity.
• It is represented by the Greek letter ν (nu).

Explanation

• According to Fleming's Right-Hand Rule, the forefinger points in the direction of the magnetic field (lines of force).
• The thumb shows the motion of the conductor.
• The forefinger shows the magnetic field (N → S).
• The middle finger shows the induced current (or induced e.m.f.).
• This rule is used for electric generators.

Explanation

• Sound waves in solvents (like liquids) travel as longitudinal waves, where particles vibrate parallel to the direction of wave propagation.
• These are a type of mechanical wave, requiring a medium to travel.

Explanation

• A diode is a semiconductor device that allows electric current to flow in only one direction.
• It conducts current in forward bias and blocks it in reverse bias.
• A diode is made by joining P-type and N-type semiconductors to form a P-N junction.
• It is widely used for rectification, converting AC into DC.
