As we've seen, astronauts measure their mass by measuring the period of oscillation when sitting in a chair connected to a spring. the body mass measurement device on skylab, a 1970s space station, had a spring constant of 606 n/m. the empty chair oscillated with a period of 0.848 s. what is the mass of an astronaut who oscillates with a period of 2.26 s when sitting in the chair?

mass of astronaut is M 67.362 kg

Explanation:

Given details:

spring constant k = 606 N/m

Time T = 0.848 s

The time period is

So the mass of the empty chair is

                   = 11.038 kg

When astronaut is sitting in the chair then the time period is

                  m' = 78.40 kg

mass of astronaut is M = m' - m

                                              = (78.40 kg) - ( 11.038 kg)

                                              = 67.362 kg

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
