At time t=0 a grinding wheel has an angular velocity of 26.0 rad/s . it has a constant angular acceleration of 30.0 rad/s2 until a circuit breaker trips at time t = 2.20 s . from then on, the wheel turns through an angle of 440 rad as it coasts to a stop at constant angular deceleration. through what total angle did the wheel turn between t=0 and the time it stopped? express your answer in radians. at what time does the wheel stop? express your answer in seconds. what was the wheel's angular acceleration as it slowed down? express your answer in radians per second per second.

-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

hope this
