Exploring Gravity and Dimensions

What is the hierarchy problem in the context of gravity?

• The challenge of explaining why gravity is much weaker than other forces.

• The issue of gravity not being observable at small scales.

• The difficulty in measuring gravity accurately.

• The problem of unifying gravity with electromagnetism.

According to the inverse square law, how does the strength of gravity change with distance?

• It decreases with the square of the distance.

• It increases with the square of the distance.

• It remains constant regardless of distance.

• It increases linearly with distance.

What would happen to gravity if our universe had four spatial dimensions?

• Gravity would increase with distance.

• Gravity would follow an inverse cube law.

• Gravity would become stronger than other forces.

• Gravity would remain unchanged.

What is meant by 'compactified' dimensions?

• Dimensions that are visible to the naked eye.

• Dimensions that are wound up very small.

• Dimensions that are infinitely large.

• Dimensions that do not affect gravity.

Who originally designed the apparatus used in the Cavendish experiment?

• Oscar Klein

• Albert Einstein

• John Mitchell

• Isaac Newton

What is a torsion pendulum used for in the Cavendish experiment?

• To detect electromagnetic waves.

• To measure the speed of light.

• To measure tiny forces by observing twists.

• To calculate the mass of planets.

How did Cavendish protect his experiment from external influences?

• By isolating it from gravitational influences.

• By conducting it in a vacuum.

• By using a telescope to measure displacement.

• By shielding it from magnetic fields.

What is the significance of modern Cavendish experiments?

• They have disproven the existence of extra dimensions.

• They have confirmed the existence of extra dimensions.

• They have shown that gravity is stronger than previously thought.

• They have improved the precision of gravitational measurements.

What challenge arises when testing gravity at scales below 1 micrometer?

• The Casimir force becomes significant.

• Gravity becomes too strong to measure.

• The inverse square law no longer applies.

• Electromagnetic interference increases.

What is the current understanding of the number of spatial dimensions?

• There are more than three spatial dimensions.

• There are exactly three spatial dimensions.

• There are no spatial dimensions.

• The number of spatial dimensions is constantly changing.
