Which is better alloy or copper in AC? Copper has a heat transfer coefficient higher than aluminium. That means, copper is a better heat exchanger than aluminium. 2) Cost and Pliability (The quality of being easily bent): Copper is costlier than aluminium, which increases the cost of making an air conditioner and thereby the price […]
Can I set my AC to 70?
Can I set my AC to 70? If changing your filter does not remedy the situation, call for service. Do not set your thermostat below 70 degrees as it will not cool any faster and could freeze up the system causing more problems. Understand that there is generally a 20 degree difference between indoor air […]
Which has higher heat capacity metal or water?
Which has higher heat capacity metal or water? We would say that water has a high heat capacity (the amount of heat required to raise the temperature of an object by 1°C.) Water is very resistant to changes in temperature, while metals in general are not. Does plastic or metal cool faster? Here, for instance, […]

What would increase the force of gravity between two objects quizlet?
What would increase the force of gravity between two objects quizlet? Terms in this set (17) If the mass of an object increases, the force acting on it, such as gravitational force, also increases. The tendency for an object in motion to remain in motion is called orbital speed. Is Gravity present on moon? The […]
What battery is best for an electromagnet?
What battery is best for an electromagnet? The do-it-yourself assembly of an electromagnet is a common science experiment that demonstrates the marriage of electricity and magnetism as a unified force. You can use any type of battery for this project, including a 9-volt (9V) battery. What will happen if we increase the number of turns […]

Como se mide la potencia de un aerogenerador?
¿Cómo se mide la potencia de un aerogenerador? La potencia es igual a la energía dividida por el tiempo. Teniendo en cuenta los resultados obtenidos: P = (η·0,5·π·ρ·r²·v³·t) / t = η·0,5·π·ρ·r²·v³. ¿Cómo se produce y se genera la energía eolica? En estos la energía eólica mueve una hélice y mediante un sistema mecánico se […]
