Suppose that we have a monochromatic non-diverging beam of x rays that are incident on a slab of Pb. Inside the Pb plate there are three apertures (openings) that allow the beam of x rays to be incident on a water phantom as shown in the figure below.
(a) In the compartment of water denoted by the dotted line, calculate:
(i) The number of photoelectric interactions per second,
(ii) The number of Compton interactions per second
(iii) The number of coherent scatters interactions per second.
(iv) The energy absorbed per second.
(b) What thickness of air (dair) is needed in order that the number of Compton scatter interactions in air are the same as in the volume of water in (a)?
(c) What thickness of bone (dbone) is needed in order that the number of Compton scatter interactions in bone are the same as in the volume of water in (a)?
An object moving with a speed better than the speed of sound is called to be move with a supersonic speed.
A circuit which employs a DIRECT CURRENT source has a branch which contains a capacitor. After the circuit has reached a steady state, what is the magnitude of the current in the c
Demerits of Vacuum Diode over Semiconductor Diode (i) Bigger in size (ii) Less efficiency (iii) Expensive
Q. In 17 Cl 35, Compute the number of protons, neutrons and electrons. Number of electrons = 17, Number of protons = 17, Number of neutrons = 18
what is entropy and how is it useful in our everyday life?
A filter of the form G ( z ) = z 2 /( z - p )( z - p ) with p = re 4ω n will be studied. With r = 0 . 95 and ω n = Π/10 , plot the time response to
A negatively charged particle is cranium due north straight toward a straight vertical wire which carries a downward current. What is the direction of the force if any use on the c
I think it is same as the apex angle of the prism or the angle of the prism. since it decides the angle of deviation as i+e=D+A(angle of the prism),D=deviation.
Definition: The electric field in a region is shown by continues lines (also known as lines of force). Field line is an imaginary line along which a positive test charge will move
Maxwell's equations (J.C. Maxwell; 1864): Four elegant equations that describe classical electromagnetism in its entire splendor are following.
