n observer notices that a moving clock runs slow by a factor of exactly $10.$ The speed of

the clock is:

A$)0\mathrm{.}0100$c

B$)0\mathrm{.}100$c

C$)0\mathrm{.}900$c

D$)0\mathrm{.}990$c

E$)0\mathrm{.}995$c

$33.$ A meson when at rest decays $2$s after it is created. If moving in the laboratory at $0\mathrm{.}99$c$,$ its

lifetime according to laboratory clocks would be:

A$)$ the same

B$)0\mathrm{.}28$s

C$)4\mathrm{.}6$s

D$)14$s

E$)$ none of these
