1. Consider two monoenergetic photon beams with the same photon fluences. In one beam the photons are 100 keV and in the other they are 1 MeV. Determine the most appropriate relation between both exposures (X).
2. Electrons with kinetic energy of 1.0 MeV have a speci c ionization in air of 6000 IP/m whereas alpha particles of 2.0 MeV have an LET in air of 0.175 keV/μm. What value is closest to the ratio LET(alphas)/LET(electrons) in air.
why specific heat is different at different temperature?
Motion of an object in a plane is known two dimensional (2-D) motions. For 2-D motion acceleration or velocity can be defined by two elements in any two mutually perpendicular dire
(i) A closed system consisting of 2 kg of a gas undergoes a process during which the relationship between pressure and specific volume is pv1.3 = c. The process begins with 1 p =1b
The frequency of a wave is 50 Hertz and its wavelength is 25 meters. What is the velocity of this wave? Ans: The velocity of given wave is 1250 meters/second.
A 2.00 x 10 3 -g sample of water at 100.0°C is mixed with a 4.00 x 10 3 -g sample of water at 0.0°C in a calorimeter. What is the equilibrium temperature of the mixture?
Derive mathematical equation for an electromagnetic wave travelling in a charge free conducting medium in terms of electric field vector.
What is Power? Power is how fast work is done or energy is used. Example: Remember that cheeseburger (~1/4 pound) I lifted up one meter to do one joule of work? If you now
Regard as a pair of two identical capacitors. In which situation is the capacitance of the pair greater? Ans: The effective capacitance of a couple of capacitors in series
