Explanation:

1 Solid ball, no subatomic particles. This model was proposed by some Greek Philosophers and John Dalton in 1803. That matter was made up of small indivisible substances called atoms.

4 Solid ball of positive materials with electrons scattered throughout. (Plum Pudding Model). This model was proposed by JJ Thomson in 1904. That the atom contained a large positively charged ball with negative charges scattered about.

3 # The atom is mostly empty space. A dense nucleus with protons and neutrons is in the center and electrons travel around it randomly. This model was proposed by Ernest Rutherford in 1911. The center of the atom was dense and positively charged with protons and neutrons surrounded by electrons orbiting it and most of the space between the nucleus and the electron orbit empty.

2 A dense nucleus with protons and neutrons is in the center of the atom. The electrons travel around the nucleus in distinct energy levels. This model was proposed by Niels Bohr in 1913. This was due to the fact that atoms only emit light at certain wavelengths which would imply that they have discrete energy levels which the electrons are contained in.

Сл A dense nucleus with protons and neutrons in the center of the atom. The electrons are found in "electron clouds" which surround the nucleus. Electron cloud show where electrons are likely to be, but not exactly where they are. This model was proposed by Erwin Schrodinger in 1926 through the solution of the Schrodinger wave equation. The position of the electron is assumed to to be a probability in an electron cloud.

-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

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
