Which of the following is a true statement?

1. Which of the following is a true statement? • Albert Einstein was born in Switzerland. • All of Albert Einstein’s teachers considered him to be the best-performing classroom student that they had encountered. • Albert Einstein elected to take a job as a patent examiner in spite of having offers for faculty positions at universities. • Albert Einstein got married twice – first to MilevaMaric, and later to his cousin Elsa Loewenthal. • Albert Einstein was a highly accomplished teacher and mentor of undergraduate students, many of whose students went on to successful research careers in physics.

2. Which was NOT among the topics about which Einstein published during his miraculous year of 1905? • Brownian motion • The electrodynamics of moving bodies • The equivalence of inertia and energy • the photoelectric effect • The redshift of light as it climbs in a gravitational field

3. Einstein was the first to use the concepts of spacetime and worldlines in connection with his special theory of relativity. • True • False

4. Why do chemical engineers use the rule that the mass of the products of a chemical reaction must equal the mass of reactants? • Because the equation E=mc2 does not apply to chemical reactions. • Because the energy releases in chemical reactions are small enough that the corresponding mass decreases are negligibly small. • It is not true that the chemical engineers use a “mass conservation” rule.

5. In Einstein’s explanation of the photoelectric effect, a monochromatic beam of light is supposed to consist of a stream of photons, with the energy E of each photon equal to Planck’s constant h times ______ of the light. • the frequency • the intensity • the wavelength • None of the above

6. According to Einstein’s special theory of relativity, ______________ . • the measured speed of light is the same in every inertial frame of reference • moving clocks run slow • moving objects are shortened longitudinally • if two events are simultaneous in one frame of reference, they are typically NOT simultaneous as observed in a frame reference moving with respect to the first • All of the above are true

7. Which of the following effects had already been observed before Einstein developed the general theory of relativity? • deflection of starlight as it passes near the Sun • excess precession in the perihelion of the planet Mercury • the redshift of light as it climbs in a gravitational field • All of the above had already been observed • None of the above had been observed before Einstein developed general relativity

8. There are no devices of practical importance for which the general theory of relativity plays an important role. • True • False

9. In 1935, Einstein and two co-authors published a paper expressing doubt that ______________ can provide a correct and complete description of the physical world. • logical thought • mathematics • quantum mechanics • string theory
