### What is a key difference between General Relativity and Special Relativity?

• A.

Special Relativity deals with accelerating frames of reference

• B.

General Relativity is based on quantum mechanics

• C.

Special Relativity includes gravitational effects

• D.

General Relativity is limited to light speed

• E.

None of the above

C. Special Relativity includes gravitational effects
Explanation
The key differences between General Relativity and Special Relativity are:
Special Relativity: Formulated by Albert Einstein in 1905, Special Relativity deals with the physics of objects moving at constant speeds in straight lines (inertial frames of reference). It does not include the effects of gravity. It introduces the concepts of time dilation and length contraction for objects moving at speeds close to the speed of light.
General Relativity: Formulated by Einstein in 1915, General Relativity extends Special Relativity to include acceleration and gravity. It describes gravity not as a force but as a curvature of spacetime caused by mass and energy. This theory applies to all frames of reference, whether inertial or accelerating.
The correct key difference not listed in the options is:
Special Relativity deals with inertial frames of reference, while General Relativity includes both inertial and non-inertial (accelerating) frames of reference and incorporates the effect of gravity as a curvature of spacetime.

Rate this question:

• 12.

### How does General Relativity account for the phenomenon of time dilation?

• A.

Due to the effect of electromagnetic fields

• B.

Due to the motion of matter

• C.

Due to the presence of dark matter

• D.

Due to the curvature of spacetime

D. Due to the curvature of spacetime
Explanation
Time dilation in General Relativity occurs due to the warping of spacetime in the presence of mass. Clocks in strong gravitational fields run slower compared to clocks in weaker fields.

Rate this question:

• 13.

### What did the LIGO and Virgo collaborations detect in 2015, confirming General Relativity?

• A.

Gravitational waves

• B.

Dark matter

• C.

Neutrinos

• D.

A. Gravitational waves
Explanation
The LIGO and Virgo collaborations detected gravitational waves in 2015, providing direct evidence of their existence and confirming a key prediction of General Relativity.

Rate this question:

• 14.

### What is the main concept behind the Equivalence Principle in General Relativity?

• A.

The inertial mass is equal to the gravitational mass

• B.

The speed of light is constant

• C.

Time is absolute

• D.

Gravitational waves are weak

A. The inertial mass is equal to the gravitational mass
Explanation
The Equivalence Principle in General Relativity states that the inertial mass (resistance to acceleration) of an object is equal to its gravitational mass (the force it experiences due to gravity). This principle is a foundational concept in General Relativity.

Rate this question:

• 15.

### Which aspect of black holes is a consequence of General Relativity?

• A.

The event horizon

• B.

• C.

• D.

The Chandrasekhar limit
