The what energy of water in a dam is increased by raising the level of water behind the dam?
Potential Energy
Why did insulation come about?
Insulation was developed to improve energy efficiency in buildings by reducing heat transfer, thereby maintaining comfortable indoor temperatures regardless of external weather conditions. It also helps to lower energy costs and decrease reliance on heating and cooling systems. Additionally, insulation contributes to noise reduction and enhances overall building comfort and sustainability. As energy conservation became a priority, particularly in response to rising energy costs and environmental concerns, the demand for effective insulation solutions increased.
Why did the US slow its construction of nuclear plants in the 1980's?
There were increasing concerns about safety due to some high-profile disasters involving nuclear power plants - particularly at Chernobyl and Three Mile Island. They were also very costly to build, and not necessarily as economical as other sources of energy (such as oil).
What obstacles had to be overcome for hydropower to be accepted?
The acceptance of hydropower faced several obstacles, including environmental concerns such as ecosystem disruption and fish migration due to dam construction. Social issues arose from the displacement of local communities and changes to traditional livelihoods. Additionally, economic challenges related to the initial high costs of building infrastructure and securing funding had to be addressed. Over time, advancements in technology and increased awareness of renewable energy benefits helped mitigate these concerns and promote hydropower's acceptance.
Why generator rotor speed reduces when load in the grid is increased?
FOR A CONSTANT POWER INPUT i.e THE GENERATION IS CONSTANT AND IF THE LOAD IS INCREASED THEN THE INCREASED POWER DEMAND IS SUPPLIED BY THE STORED KINETIC ENERGY IN THE ROTOR 1/2JW² HENCE THE SPEED OF THE ROTOR DECREASES.
What was result of the accident at three mile island?
Many Americans began to worry about nuclear power- Apex
What resulted from the accident at Three Mile Island?
Many americans lost faith in nuclear power(apex)
How have environmental and energy concerns affected the automatic controls for regulating residential and commercial environments and appliances industry?
Concerns about the environment and the resulting legislation have helped this industry to grow. Environmental issues created an increased demand for systems that control air quality and conserve energy
What event caused many Americans to woory about nuclear power?
The Three Mile Island nuclear accident in 1979, where a partial meltdown occurred at a nuclear power plant in Pennsylvania, sparked concern among Americans about the safety of nuclear power. The incident led to increased scrutiny of nuclear plants and raised questions about the potential risks associated with nuclear energy.
Is NOT a potential benefit of using more nuclear energy?
The plants are very expensive to build, and could be dangerous in case of an accident.
Why has the production of nuclear energy slowed down?
The production of nuclear energy has slowed down due to factors such as high upfront costs, concerns about nuclear accidents and radioactive waste disposal, competition from renewable energy sources, and regulatory challenges. Additionally, public perception and opposition to nuclear power have also played a role in its decline.
Does increased energy increased that particles are moving faster r slower?
Increased energy makes particles move faster.
What is increased in all energy transfers?
Entropy is increased.
Who is most at risk in a nuclear energy accident?
Those most at risk in a nuclear energy accident are the workers at the nuclear facility itself.
What are the 2 concerns of physics?
Two concerns of physics are the study and the understanding of matter and energy and their interactions.
What are the environmental concerns of solar energy?
No there are not any enviromental risks of solar energy.
How can the energy of the molecules of a solute and solvent be increased?
The energy of molecules in a solute and solvent can be increased by adding outside energy, say, heat, for instance.
