Awire has a current that flows to the right. which describes the magnetic field produced by the current? a. straight lines along the wire to the rightb. straight lines along the wire to the leftc. circles around the wire that go in at the topd. circles around the wire that go in at the bottom

magnetic field near any point of wire is given by right hand thumb rule

As per right hand thumb rule if we put our thumb along the current in the wire then magnetic field will always along the curl of fingers.

So magnetic field lines will always forms closed loop around the wire.

As per right hand rule we can say the magnetic field will be

D. circles around the wire that go in at the bottom

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

-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
