Using a single dimensional equation, estimate the number of steps it would take you, walking at your normal stride, to walk from the Earth to Alpha Centauri, a distance of 4.3 light-years. The speed of light is 1:86 x 105A miles/s.
Energy has dimensins mass times distance^2 divided time^2. In these expressions, m is mass, x is distance, t is itme, v is speed, and a is acceleration. Which expressoin as dimensions equivalent to energy?
mx^2/t
max
ma/t
max/t
mv^2/x
A light-year (ly) is the distance light travels in one year (at speed of 2.998 ×× 108 m/sm/s ). An astronomical unit (AU) is the average distance from the Sun to Earth, 1.50 ×× 108 kmkm.1 yearyear = 3.156 ×× 107 ss.
a. How many meters are there in 6.50 lyly ?
Express your answer using three significant figures.
b. How many AUAU are there in 6.50 lyly light-year?
Express your answer using three significant figures.

- According to the Theory of Relativity, the length of an object depends on its velocity v with respect to an observer. For an object whose length at rest is 10 m, its observed length L satisfies the equation c2L2 + 100v2 = 100c2 where c is 300,000 km/s, the speed of light. (Round your answers to four decimal places.)
