Please Help Me! Only two questions.?
2. The matter contained in living organisms, also called _____, contains chemical energy. (1 point) biomass fossil fuels kinetic energy energy transformation 3. A _____ transforms kinetic energy into electrical energy. (1 point) generator turbine power plant steam line
This physics question confuses me. Can someone explain and show how to get the answer. The steps I mean..?
NASA has developed Deep-Space 1 (DS-1), a spacecraft that is scheduled to rendezvous with the asteroid named 1992 KD (which orbits the sun millions of miles from the earth). The propulsion system of DS-1 works by ejecting high-speed argon ions out the rear of the engine. The engine slowly increases the velocity of DS-1 by […]
A few Thermodynamics Physics review questions?
Can someone help me with these A heat engine consists of an oil fired steam turbine driving an electric power generator with a power output of 120 megawatts. The thermal efficiency of the heat engine is 40 percent. a. Determine the time rate at which heat is supplied to the engine. b. If the heat […]
Can anyone PLEASE answer this question about Geothermal Energy?
While geothermal energy use is efficient, reliable, and environmentally friendly, it currently meets less than 1% of U.S. power needs. Why is that?
questions about energy?
i have some school homework for science and it’s really hard can anyone tell me….. how to build a candle operated steam turbine from simple materials Build a simple wind powered generator and build a working model for a solar water heating system using every day materials

My question is why does Nikola Tesla get overlooked?
Einstein, Newton, Plank, Hawking, Bohr … But damn didn’t Tesla create things 100 years ago, that people still think don’t exist?? I respect this man, for how he wanted people to have free energy. But greed took over…
answer this question why did nikola tesla create the tesla coil?
Why did Nikola Tesla create the Tesla Coil
I have a question about alternative fuel?
How reliable is alternative fuel? (ethanol, hydrogen, natural gas, etc).
Why do quality questions about Nikola Tesla get deleted?
Induction motors, magnifying transmitters, good stuff.
A question to all 911 conspiracy thoretists: how likely that explosion of oil rig was also inside job?
Can you help me with my alternative energy science questions which has energy transformations and generators?
1. What form of energy is released from a bowling ball, a car, and a computer? 2. What energy transformation occurs when a solar calculator operates? 3. What energy transformation occurs when burning a campfire? 4. What energy transformation occurs when you rub your hands together? 5. Why does a student feel hot when they […]
NRC Questions Westinghouse Reactor Design
The Nuclear Regulatory Commission has questions about the a design by Westinghouse for a new reactor. Regulators say the AP1000 doesn’t meet some safety standards. Meanwhile, 14 projects have been put on hold until Westinghouse can prove otherwise. Clean Skies News’ Executive Editor Margaret Ryan has more.
Here’s my question and no I’m not a conspiracy weirdo! Please serious discussion.?
What do we think of our government and how they are handling our energy crisis? This very real energy crisis has been off and on since the 1960’s and ever since then our government has done little or nothing to really fix it. Somehow this country (Bible humpers mostly I believe) voted Bush’s into office […]
General Physics question about forces and newton’s laws of motion! please help, hw due on sunday!?
A cable is lifting a construction worker and a crate, as the drawing shows. The weights of the worker and crate are 995 and 1450 N, respectively. The acceleration of the cable is 0.620 m/s2, upward. (a) What is the tension in the cable below the worker? N (b) What is the tension in the […]
Serious question about the green movement?
why? cfls have been around since 1975 and fluorescent lamps since 1951. why are people just now realizing the energy efficiency of these lamps and why are people buying organic? ORGANIC! if you’re scared of chemicals, wash your produce. scared of hormones? GO VEGETARIAN! Government conspiracy or are we just getting dumber?
can you answer these questions about geothermal energy for me?
what is a detailed description of geothermal energy? how is it generated? Where does the energy come from? what are advantages of geothermal energy? what are disadvantages of fossil fuels?
Question for the “Iraq War is all about oil” conspiracy theorists…?
If the Iraq war was all about oil, why didn’t we just buy it from them? It would be a lot cheaper than the war we are in now! Hmmmm.
Question on Twin Ion Engines?
You might remember “twin ion engines” from Star Wars (though you probably don’t). Apparently NASA has actually developed TIEs. These engines don’t travel nearly as fast as in the movie though. They use mercury ions and solar power for propulsion. I don’t understand how this is possible. Normal rocket engines are able to propel themselves […]
Thermodynamics & Heat Transfer question… Steam efficiency etc..?
A power plant taps steam superheated by geothermal energy to 505 K (the temperature of the hot reservoir) and uses the steam to do work in truning the turbine of an eletric generator. The steam is then converted back into water in a condenser at 323 K (the temperature of the cold reservoir), after which […]
