i realy need help if you can plz? physic

hi every one!
this is my 1st time & visit!!
i dont realy expect 4rm you to answer my question BUT i realy need your help if you can??

am talking here about physic? its the start of the year thats why am abit not in the stright line.......


these are the questions if you can help ;-)

Ø Identify the uses of energy and the typical value of energy for some application.
o Kinetic energy
o Potential energy
o Chemical energy
o Thermal energy
o Electrical energy
o Electromagnetic energy
o And at last nuclear energy?

Ø Identify the energy transfers involved in:
o The generation of electrical energy
o Obtaining thermal energy from fuels
o Heat exchanges

Ø The fallowing are examples of energy transfers. Describe a real-life situation of each one; indicate at least one with a numerical value:
o Metabolism
o Potential to kinetic

Ø Briefly describe at least three examples of energy usage in the workplaces including:
o What kind of energy
o How/what they do with it
o How is it used?

And I know its too much? But am realy thankin you for taking time to answer this question or even reading it :-)
1. you could use somekind of search engines to search for the values and apps of these energies...but i could give you a hint..
electrical energy- obviously, the 100W lamp you might be using at home!
nuclear energy-the only place is the nuclear extraction sites..or the nuclear reactor..
electromagnetic energy might be the door bell..or even part of the fridge..
chemical- batteries, yourself(!!!)
2. generating electrical energy using coal would contain the following energy transfer:
chemical energy ----- heat energy---------electrical energy
thermal energy from fuels:sorry..not sure of this :smile:

3. metabolism...this is basically...chemical energy-----kineticenergy right?
this would happen in the body of living organisms..
potential-kinetic energy..gosh! there are many for this.... throwing a ball intothe air, and catching it again....releasing an arrow from the bow..
but i dont know the values..

hope it helps...
