Change the time flow rate to 1 day (solar day). note the position of the moon and the background stars and click the step time forward button to advance time by 1 solar day. then change the time flow rate to 1 sidereal d. (sidereal day) and watch the moon and stars in the view when you click the step time forward button again, this time to advance time by 1 sidereal day. repeat these steps to decide which of the following statements is not correct. a in 1 sidereal day, the background stars do not appear to move but the moon does. b in a 1 day time step, the background stars and the moon both move. c looking at the time display, a sidereal day is shorter than a normal 'solar' day by about 4 minutes. d in 1 day, the stars and the moon both appear to move in the same direction.

-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
