Are combustion engines more efficient? How efficient are engines? Combustion engines are stupefyingly inefficient. Most diesel engines do not even have a thermal efficiency of 50%. Of every gallon of diesel burned by a combustion engine, less than half of the energy generated becomes mechanical energy. How long will internal combustion engines be around? The […]

What is the change in internal energy of the system when no heat is absorbed by the system from the surroundings but work is done by the system what type of wall does the system have? adiabatic What is thermally conducting walls? Consider two systems A and B which are separated by a conducting wall. […]
What are the different types of reflections?
What are the different types of reflections? Types of reflection Reflection-in-action and Reflection-on-action. Two main types of reflection are often referred to – reflection-in-action and reflection-on-action. Reflection-in-action. This is the reflection that takes place whilst you are involved in the situation, often a patient interaction. Reflection-on-action. How do you write a good personal reflection? How […]
Why were Russian peasants so poor?
Why were Russian peasants so poor? The reforms in agricultural also disappointed the peasants. By 1900 around 85 per cent of the Russian people lived in the countryside and earned their living from agriculture. The nobility still owned the best land and the vast majority of peasants lived in extreme poverty. Why was there a […]

What is neap tide simple?
What is neap tide simple? A neap tide—seven days after a spring tide—refers to a period of moderate tides when the sun and moon are at right angles to each other. During full or new moons—which occur when the Earth, sun, and moon are nearly in alignment—average tidal ranges are slightly larger. This occurs twice […]
What color is lowest in energy?
What color is lowest in energy? Red What are the forbidden colors? Red-green and yellow-blue are the so-called “forbidden colors.” Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they’re supposed to be impossible to see simultaneously. The limitation results from the way we perceive color in […]

What is the main purpose of capacitor?
What is the main purpose of capacitor? Capacitors are widely used in electronic circuits for blocking direct current while allowing alternating current to pass. In analog filter networks, they smooth the output of power supplies. In resonant circuits they tune radios to particular frequencies. What is the importance of capacitor? Capacitors have many important applications. […]
Why do they say feels like temperature?
Why do they say feels like temperature? The “feels like” temperature is a measurement of how hot or cold it really feels like outside. For example, skin that is exposed to wind and cold temperatures will make a person feel that it is colder outside than it really is because heat is drawn away from […]
