Explanation

• An inclined plane is a flat surface tilted at an angle to help move objects up or down with less effort.
• It reduces the force needed compared to lifting vertically.
• Mechanical advantage = distance along incline ÷ vertical height.

Explanation

• Weight depends on gravitational force acting on mass.
• The Moon’s gravity is about 1/6th of Earth’s, so your weight decreases.
• Your mass remains the same, only weight changes.

Additional information:

• Weight change occurs due to difference in gravity.
• Mass is constant everywhere in the universe.

Explanation

• Weight is the force of gravity acting on an object's mass.
• It depends on mass of the object and gravitational acceleration (g).
• Formula: Weight (W) = Mass × Gravity (W = m × g)

Additional information:

• Earth: g ≈ 9.8 m/s²
• Moon: g ≈ 1.6 m/s² (weight is less)

Explanation

• Frictional force arises when two surfaces slide or move against each other.
  • It opposes the motion and can generate heat.
  • Friction is essential in walking, driving, and machine operation.

Explanation

• A diluted solution has a low ratio of solute to solvent, meaning it contains less solute.
• It is the opposite of a concentrated solution, which has more solute.
• Diluted solutions are often used when a weaker solution is needed.

Explanation

• Paper Chromatography is a method used to separate and identify colored substances, especially dyes in a mixture.
• It works based on different rates of movement of substances through absorbent paper with a solvent.

Additional information:

• Filtration – separates solids from liquids.
• Sublimation – separates a solid that sublimes from a mixture.
• Distillation – separates liquids based on boiling points.

Explanation

The correct answer is: Molecules do not collide with one another

Gas molecules:

• Are widely separated
• Have low attractive forces
• Are free to move in any direction
• Collide with one another
