To lift a car, you use a hydraulic lift filled with a fluid that has density of 1 1200 kg/m3. the radius of one half of the lift is 0.5 meters and the diameter of the other half of the lift is 2.5 meters. before you put a mas of 200 kg on the smaller piston, the heights of each piston are the same. if the car weighs 2200 kg, how high will it be raised?

3.8 cm

Explanation:

density of fluid = 11200 kg/m^3

r = 0.5 m

R = 2.5 / 2 = 1.25 m

m = 200 kg

f = 200 x 10 = 2000 N

M = 2200 kg

F = 2200 x 10 = 22000 N

a = 3.14 x r^2 = 3.14 x 0.5 x 0.5 = 0.785 m^2

A = 3.14 x R^2 = 3.14 x 1.25 x 1.25 = 4.9 m^2

P1 = f / a = 2000 / 0.785 = 254.77 Pa

P2 = F / A = 22000 / 4.9 = 4489.8 Pa

Let h be the difference in height in both the cylinders

h x density x g = P2 - P1

h x 11200 x 10 = 4489.8 - 254.77

h = 0.038 m = 3.8 cm

explanation:

-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
