Explain the function of various parts of a data acquisition
system. What are the industrial applications of PC-based data
acquisition system? and how it assists in calibration and testing
of measurement sensors?
Cyanide is used in several industrial applications, such as
mining gold and electroplating silver. A danger of working with
cyanide solutions is the potential hazard of releasing highly toxic
hydrogen cyanide gas. What conditions are necessary to ensure that
less than 1% of the cyanide in a particular solution is chemically
present as HCN rather than CN-? (HCN pKa= 9.2)
(A) pH > 11.2
(B) pH > 10.2
(C) pH > 9.2
(D) pH > 8.2
(E) pH > 7.2...

Many radioisotopes have important industrial, medical, and
research applications. One of these is 60Co, which has a half-life
of 5.20 years and decays by the emission of a beta particle (energy
0.310 MeV) and two gamma photons (energies 1.17 MeV and 1.33 MeV).
A scientist wishes to prepare a 60Co sealed source that will have
an activity of at least 13.7 Ci after 37.0 months of use. If the
activity is 13.7 Ci, how many 60Co atoms are in the...
