Scientists are working hard to develop nuclear fusion reactor Nuclei of heavy hydrogen, _(1)^(2)H , known as deuteron and denoted by D , can be thought of as a candidate for fusion rector . The D-D reaction is _(1)^(2) H + _(1)^(2) H rarr _(2)^(1) He + n+ energy. In the core of fusion reactor, a gas of heavy hydrogen of _(1)^(2) H is fully ionized into deuteron nuclei and electrons. This collection of _1^2H nuclei and electrons is known as plasma . The nuclei move randomly in the reactor core and occasionally come close enough for nuclear fusion to take place. Usually , the temperature in the reactor core are too high and no material will can be used to confine the to plasma for a time t_(0) before the particles fly away from the core. If n is the density (number volume ) of deuterons , the product nt_(0) is called Lawson number. In one of the criteria , a reactor is termed successful if Lawson number is greater then 5 xx 10^(14) s//cm^(2) it may be helpfull to use the following boltzmann constant lambda = 8.6 xx 10^(-5)eV//k, (e^(2))/(4 pi s_(0)) = 1.44 xx 10^(-9) eVm Result of calculations for four different design of a fusion reactor using D-D reaction are given below. which of these is most promising based on Lawson criterion ?

Suppose the evaporation rate of water in a lake is given by the equation E=((T_(a)-T_(b))/(700)-(V)/(T_(w)))/(h^(4)) , where E is the evaporation rate in gallons/day. T_(a) is the air temperature, T_(d) is the dew point temperature, V is the volume of water in the table, T_(w) is the water temperature, and h is the number of hours the water is exposed to sunlight. Which of the following expresses T_(w) in terms T_(a), T_(b), V, E, and h ?

An impluse laser may be treaed as a source of phtons that are emitted during the time interval of the pulse which is followrd by a time interval when no photons are produced. Pulse are periodically repeated. A laser beam of diameter d = 10 microns is directed upward and is perpendicular to the then foil surface which has an index of reflection rho = 0.50 (see the sketch of the experiment). The index of reflection of the surface is the ratio of the relected energy of foil that can be supported in the air solely by the light pressure of the laser beam ?

For the reaction 5Br^(-)(aq)+BrO_(3)^(-)(aq)+6H^(+)(aq)rarr 3Br_(2)(aq)+3H_(2)O(l) the reate expression was found to be -(d[BrO^(3-)])/(dt)=k[Br^(-)][H^(+)]^(2)[BrO_(3)^(-)] Which of the following statements is /are correct? I. Doubling the intial concentration of all the reactants will increase the reaction rate by a factor of 8. II. Unit of rate constant of the reaction in a buffer solution is "min"^(-1) III. Doubling the concentration of all the reactants at the same time will increase the reaction rate by a factor of 16 IV. rate of conversion of BrO_(3)^(-) and rate of disappearance of Br^(-) are the same

Luciano measured the amount of water that evaporated over a period of time from a container holding w ounces of water, where w is greater than 12. By the end of the first day, the cub had lost 2 ounces of water. By the end of the 7th day, the cup had lost an additional 8 ounces of water. By the end of the 11th day, the cup had lost half of the water that remained after the 7th day. Which of the following represents the remaining amount of water, in ounces, in Luciano's container at the end of the 11th day?

A small bottle contains powered beryllium Be & gaseous radon which is used as a source of alpha -particles. Netrons are produced when alpha- particles of the radon react with beryllium. The yield of this reaction is (1//4000) i.e. only one alpha -particle out of induced the reaction. Find the amount of radon (Rn^(222)) originally introduced into the source, if it prouduces 1.2 xx 10^(6) neutrons per second after 7.6 days. [ T_(1//2) of R_(n) = 3.8 days]
