Question

When it comes to GRAVITY IN BOTH SPECIAL AND GENERAL RELATIVITY, what or why is... - choose one of the three alternatives each for a) - e)

a) TIDAL EFFECTS (1. Exists only in Newtons theory - 2. Depends on different curves in Spacetime - 3. Exists only in free-falling reference frames)

b) GENERAL RELATIVITY SAYS (1. Gravity is stronger than normally - 2. Gravity is weaker than normally - 3. Gravity does not exist)

c) GRAVITATIONAL EFFECTS (1. Depends on curves in space - 2. Depends on curves in spacetime - 3. Depends only on energies)

d) GRAVITY WAVES (1. Are electromagnetic - 2. Have a speed that is proportional converse/inverse to their wavelength - 3. Carries away energy from accelerating masses)

e) BLACK HOLES (1. Releases more mass-energy than nuclear reactors - 2. Does not cause gravity - 3. Have details that depends on how they were created)
