Question
12. A difference between the Special Theory of Relativity and the General Theory of Relativity is the inclusion of this in the General Theory. a. Gravity on planets b. Relative Motion c. The Constant Speed of Light d. Acceleration e. The Effect of the Frame of Reference 13. For a thermonuclear weapon (an H-bomb) to work, it requires a. only an electrical trigger. b. only a critical mass of a fissionable material. c. only a critical mass of fusionable materials. d. both a critical mass of fissionable material and fusionable materials. 14· The Michelson-Morley experiment demonstrated that a. the speed of light was 3,000,000 km/s. b. the speed of light changes depends on how it is measured relative to the motion of the Earth. c. the speed of light is the same in every frame of reference. d. light depends on the ether, something that waves propagate through space e. ether does not exist. In the Twin Paradox, when he returns, the age of the twin that travels on the rock ship that approaches the speed of light will be 15. a. younger than his twin. b. older than his twin. c. the same age as his twin.Explanation / Answer
Solution:
12) a
The difference between the two theories is that the theory of general relativity throws light on the force of gravity with respect to curving four-dimensional space-time. As per Einstein, the accelerative and gravitational forces are equal and same. His findings and written document also states that all physical laws can be formulated so as to be well-founded and logical for any observer, regardless of the observer’s movement
13) c
The hydrogen bomb, also called a thermonuclear bomb, uses fusion - or atomic nuclei coming together - to produce explosive energy. Stars also produce energy through fusion.
14) d
The Michelson–Morley experiment was a scientific experiment to find the presence and properties of a substance
called aether, a substance believed to fill empty space. The experiment was done by Albert A.Michelson and
Edward Morley in 1887.
15) a
The twin paradox is a thought experiment in special relativity involving identical twins, one of whom makes a journey into space in a high-speed rocket and returns home to find that the twin who remained on Earth has aged more this occurs due to Time dialation.
