How much power does wind generate? How much energy do they generate? When the wind is blowing more than 12 miles per hour, each wind turbine can produce 1.5 megawatts of electricity. At reduced wind speeds, electricity production decreases. When wind speed exceeds 45 miles per hour the turbines shut down to protect the machinery […]
Where is the origin of electricity?
Where is the origin of electricity? This word comes from the Greek word elektron which means amber. Earlier, electricity generation began over 100 years ago, houses were lit with kerosene lamps, food was chilled in iceboxes, and rooms were warmed by wood-burning or coal-burning stoves. Who gave electricity its name? Benjamin Franklin Who was Tesla […]
How do you find displacement?
How do you find displacement? Displacement can be calculated by measuring the final distance away from a point, and then subtracting the initial distance. Displacement is key when determining velocity (which is also a vector). Velocity = displacement/time whereas speed is distance/time. What does the displacement value mean? Displacement Value can be defined as the […]
What causes a light bulb to light in a closed circuit?
What are 4 examples of convection?

Convection comes into play while boiling water. Blood Circulation in Warm-Blooded Mammals. Air-Conditioner. Radiator. Refrigerator. Hot Air Popper. Hot Air Balloon. Can life go on without […]
What is law of constant proportion class 9th?
What is law of constant proportion class 9th? The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass. This implies that any pure sample of a compound, no matter the source, will always consist of the same elements that are present in […]
Why do reaction forces exist?
Why do reaction forces exist? The reaction force is what makes you move because it acts on you. Newton’s Third Law of Motion explains that forces always come in action-reaction pairs. The Third Law states that for every action force, there is an equal and opposite reaction force. This is the reaction force. What is […]
How many principal investigators can you have?
How many principal investigators can you have? Most agencies do not recognize more than one Principal Investigator. Co-Investigator’s are permitted by some funding agencies, but Co-P.I.’s are discouraged. Who can be principal investigator? The Principal Investigator (PI) is an individual who assumes the authority and responsibility for the conduct of a research study. The PI […]
What are three conditions needed for thunderstorms to form?
What are three conditions needed for thunderstorms to form? There are three basic ingredients needed for thunderstorm development: moisture, an unstable atmosphere, and some way to start the atmosphere moving. What causes severe thunderstorms to form? Thunderstorms form when warm, moist air rises into cold air. The warm air becomes cooler, which causes moisture, called […]
What is the ideal atmospheric pressure?
What is the ideal atmospheric pressure? Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103 dynes per square centimetre, 1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals. Why don’t you feel the pressure exerted by the atmosphere? The reason we can’t feel it is […]
