Under the right conditions two high-energy "gamma ray" photons of light can create one electron and one
antielectron (called a "positron") from empty space, provided the
photons then disappear. A positron can be assumed here to have all
the same properties as an electron except that it's charge is the
opposite sign, and is thus given by the value +e. Assume that two
gamma ray photons coincide at one point in space labelled by the large
dot in the figure, and that they produce an electron and positron which
emerge from that point in exactly opposite directions with one moving
only in the +x-direction and the other moving only in the -x-direction.
Assume that all space is filled by a uniform magnetic field as indicated
in the figure, with a strength of 1.0 T, and assume that the speed of the
electron is initially twice that of the positron. Ignore any electric and
magnetic force between the electron and positron themselves.
a) Treating the electron and positron as point particles, sketch
their trajectories on the figure.

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it
