A mass spectrometer is used to examine the isotopes of uranium.
Ions in the beam emerge from the velocity selector at a speed of
3.08 ✕ 105 m/s and enter a uniform magnetic field of
0.590 T directed perpendicularly to the velocity of the ions. What
is the distance between the impact points formed on the
photographic plate by singly charged ions of 235U and
238U?

The centripetal force, 
where , 
is the mass, 
is the velocity 
is the radius of curvature.
The magnetic field, 
where 
is the charge of particle (here it is electron) 
is the magnetic field
is the angle between
and
= 
as the charge enters perpendicularly
That is 
The distance between the impact points is 
---------> eqn (1)
That is 
Rearranging, 
or 
Substituting this on eqn (1)
Which gives, 
Substitute the values for
(Charge of electron)

A certain commercial mass spectrometer is used to separate
uranium ions of mass 3.92 × 10-25 kg and charge 3.20 × 10-19 C from
related species. The ions are accelerated through a potential
difference of 107 kV and then pass into a uniform magnetic field,
where they are bent in a path of radius 1.03 m. After traveling
through 180° and passing through a slit of width 0.998 mm and
height 1.31 cm, they are collected in a cup. (a)...

A certain commercial mass spectrometer is used to separate
uranium ions of mass 3.92 ✕ 10−25 kg and charge 3.20 ✕
10−19 C from related species. The ions are accelerated
through a potential difference of 145 kV and then pass into a
uniform magnetic field, where they are bent in a path of radius
1.20 m. After traveling through 180° and passing through a slit of
width 1.00 mm and height 1.00 cm, they are collected in a cup.

A certain commercial mass spectrometer is used to separate
uranium ions of mass 3.92 × 10-25 kg and charge 3.20 × 10-19 C from
related species. The ions are accelerated through a potential
difference of 106 kV and then pass into a uniform magnetic field,
where they are bent in a path of radius 0.891 m. After traveling
through 180° and passing through a slit of width 0.774 mm and

A mass spectrometer is designed to calculate masses of
atoms. A source produces positive ions of
mass m and charge q. The ions move with a velocity v to the right,
pass through a narrow slit S1 and
enter a region between two charged plates. In this region they
experience both an electric and a
magnetic field. The electric field E is caused by the 2 charged
plates; the upper plate is (-) charged
and the lower plate is (+)...

Many radioactive isotopes are used in medicine for imaging and
treatment purposes. The specific isotopes used depends on the
particular organ or body system being studied (for example, Xe-133
is used to image lung function and blood flow.) For thyroid
imaging, isotopes of iodine are used, commonly I-123 and I-131,
which have half-lives of 13.2 hours and 8.0 days, respectively.
Why is iodine used for thyroid imaging (as opposed to any other
element)?

You are given a soil sample taken from the environment. Give
examples of any Uranium isotopes that may be present. What other
long-lived isotopes may also be present in the sample? Briefly
discuss what you understand by the term “decay chain”, giving some
examples of the type of decay processes involved

Why is uranium-235 the only isotope of uranium that can be used
as fuel for a nuclear weapon?
A uranium 235 particle is struck by a neutron creating a
fission event. The uranium splits into the following atoms and
particles: A Barium 141 atom, a Krypton 92 atom, and 3 neutrons.
Use this information and your knowledge of electrostatics,
fundamental forces, and the conservation of energy to explain
(conceptually) how this produces energy.
After a fission event occurs the Barium...
What are isotopes? how are they related with the mass number?
Must be in a paragraph form. Explain clearly. Must site examples also.

A
parallel beam of 1-MeV photons is normally incident on a sheet of
uranium, 1.0mm thick. The incident beam intensity is
10^4MeVcm-2s-1
1) calculate the energy fluence rate transmitted by the
sheet
2) what fraction of the transmitted energy fluence rate is due
to uncollided photon?
3) what physical processes are responsible for energy transfer
to the sheet?
4) what processes are responsible for energy absorption jn the
sheet?
