Particle a of charge 3.15 10-4 c is at the origin, particle b of charge -6.12 10-4 c is at (4.00 m, 0), and particle c of charge 1.10 10-4 c is at (0, 3.00 m). we wish to find the net electric force on c.(a) what is the x component of the electric force exerted by a on c?
n
(b) what is the y component of the force exerted by a on c?
n
(c) find the magnitude of the force exerted by b on c.
n
(d) calculate the x component of the force exerted by b on c.
n
(e) calculate the y component of the force exerted by b on c.
n
(f) sum the two x components from parts (a) and (d) to obtain the resultant x component of the electric force acting on c.
n
(g) similarly, find the y component of the resultant force vector acting on c.
n
(h) find the magnitude and direction of the resultant electric force acting on c.
magnitude n
direction � counterclockwise from the +x-axis

Explanation:

a)

There will be no x-component as it is acting on y-axis completely

b)

y-component will be the total force as found earlier

c)

d)

x-component of

e)

y-component of  

f)

=(x-component of )

g)

h)

from +ve x axis counter clockwise.

-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
