Are thoughts energy? As you read this article, the thoughts you are thinking of, the words your mind is processing, are all electrical impulses that can be measured if you had a few wires hooked up between your head and a machine. So thoughts are energy, the same as everything else. Which part of body […]
How much power does wind generate?
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 […]
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 […]

Put simply, the standard pushup has the potential to be one of the best body weight upper body exercises for chest, shoulder, arms and even core strength! You will […]
Why electric flux is zero in a closed surface?
Why electric flux is zero in a closed surface? If there is no net charge within a closed surface, every field line directed into the surface continues through the interior and is directed outward elsewhere on the surface. The negative flux just equals in magnitude the positive flux, so that the net, or total, electric […]
What is the role of carbon dioxide in photosynthesis and in cellular respiration?
What is the role of carbon dioxide in photosynthesis and in cellular respiration? Photosynthesis makes the glucose that is used in cellular respiration to make ATP. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other […]
What are three ways to show how energy flows through an ecosystem?
What are three ways to show how energy flows through an ecosystem? Key Points Food webs illustrate how energy flows through ecosystems, including how efficiently organisms acquire and use it. Autotrophs, producers in food webs, can be photosynthetic or chemosynthetic. Photoautotrophs use light energy to synthesize their own food, while chemoautotrophs use inorganic molecules. Why […]
