What is the difference between radiation and heat transfer by radiation? Convection is the transfer of energy by movement of a medium, whereas radiation is the transfer of energy by, well, thermal radiation. Conduction also requires a medium, but, again, it is a fundamentally different mechanism than either convection or radiation; in this case it […]
What are three signs of the inflammatory response?
What are three signs of the inflammatory response? What are the signs of inflammation? The four cardinal signs of inflammation are redness (Latin rubor), heat (calor), swelling (tumor), and pain (dolor). Redness is caused by the dilation of small blood vessels in the area of injury. Does vitamin D help with inflammation? Beyond its critical […]

What is electrical energy and its formula?
What is electrical energy and its formula? The energy consumed by an electric circuit to flow current through it is referred as electrical energy. This energy is provided by the battery to every electric charge. The work required to keep the charge Q in motion by the battery of voltage V is. W=VQ. What is […]

How do wind turbines work when it not windy?
How do wind turbines work when it not windy? If there is too little wind and the blades are moving too slowly, the wind turbine no longer produces electricity. The turbine starts to create power at what is known as the cut-in speed. Power output continues to grow as the wind speed increases, but at […]
What makes a bucket of water lighter?
What makes a bucket of water lighter? Answer. That is because the bucket is pushed up by the upthrust or buoyant force, when it is inside the water. This happens because when the bucket is in water, it experiences an upthrust in the vertically upward direction (2 forces acting to pull upwards while one force […]
