Time standards are now based on atomic clocks. A promising second standard is based on pulsars, which are rotating neutron stars (highly compact stars consisting only of neutrons). Some rotate at a rate that is highly stable, sending out a radio beacon that sweeps briefly across Earth once with each rotation, like a lighthouse beacon. Suppose a pulsar rotates once every 1.743 206 448 872 75 ± 2 ms, where the trailing ± 2 indicates the uncertainty in the last decimal place (it does not mean ± 2 ms).
How many rotation does the pulsar make in 14.0 days?
(b) How much time does the pulsar take to rotate exactly one
million times? (Give your answer to at least 4 decimal places.)
(c) What is the associated uncertainty?

Developing a Promising Manager
Training and development are the second components of the human
resource management system and are used to ensure that
organizational members develop the skills and abilities that will
enable them to perform their jobs effectively in the present and
the future. Training and development are ongoing processes because
changes in technology and the environment, as well as in an
organization's goals and strategies, often require that
organizational members learn new techniques, gain new knowledge,
and develop...

An initial deposit of $10000 is made into an account now, and a
second deposit of $18000 is made into the same account after 15
years. During the first 10 years, the account earns interest quoted
at a nominal quarterly discount rate of d %. After 10
years have passed, any money in the account earns a nominal
semi-annual interest rate of 4.6%. At the end of 30 years, the
total value of the account will be $86440. What is...

Atomic absorption spectrometry was used with the method of
standard additions to determine the concentration of cadmium in a
sample of an industrial waste stream. For the addition, 10.0 μL of
a 1000.0 μg/mL Cd standard was added to 10.0 mL of solution. The
following data were obtained: Absorbance of reagent blank = 0.041
Absorbance of sample = 0.476 Absorbance of sample plus addition =
