What are the differences between the circuits you find in your house and

the circuits on a microchip in a computer?

Check explanations below

Explanation:

The circuits in the house uses an alternating voltage, For example the United States uses 120V 60 Hz AC. The circuits in the house use electrical components that are large such as switches, Contactors and circuit breakers, distribution board, Gear switches, lampholders, etc.  

The circuits on a microchip in a computer uses a direct current supply. The voltage requirement is usually low (between 5V and 12V). In addition, micro electronic components, such transistors, resistors, low resistance wires, capacitors (in microFarad) are used.  

Typically, the Home circuit is an electrical circuit while the circuit on the computer microchip is an electronic circuit with low voltage and current requirement and low power consumption.

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

-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
