Is work done and kinetic energy Same? In other words, the work done is equal to the change in K.E. of the object! This is the Work-Energy theorem or the relation between Kinetic energy and Work done. In other words, the work done on an object is the change in its kinetic energy. W = […]

Why do bats die near wind turbines? When a wind turbine’s blades move, they cause a drop in nearby air pressure. If a bat flies too close to a turbine, this drop in air pressure can damage its lungs. They found that each wind turbine kills around 5 birds and 12 bats every year! How […]

How do you classify clastic sedimentary rocks? Clastic sediments or sedimentary rocks are classified based on grain size, clast and cementing material (matrix) composition, and texture. The classification factors are often useful in determining a sample’s environment of deposition. What are sedimentary rocks and its classification? Sedimentary rocks are classified based on their texture and […]

What is the SI unit of only current? ampere Can I use 110v in USA? It will be just fine, as long as your electricity is running to US spec. It really can be anywhere from 110V to 120V +/- 5%. Can I plug 120V into 110v? In the US, 110V isn’t a standard voltage. […]

How long do hydraulic pumps last? 20,000 hours How do I know if my hydraulic pump is bad? Pump trouble is usually characterized by increased noise, increased heat, erratic operation of cylinders, difficulty or inability to develop full output, decreased speed of cylinders or hydraulic motors, or failure of the system to work at all. […]

Can plate tectonics be proven? What is the cause of plate tectonics? Although this has yet to be proven with certainty, most geologists and geophysicists agree that plate movement is caused by the convection (that is, heat transfer resulting from the movement of a heated fluid) of magma in Earth’s interior. What are the evidences […]

What is a wave cycle? Wave cycles are pairs of a maximum value and a corresponding minimum value. The crest front wavelength is the distance between the minimum and the maximum. A min2Max cycle is a pair of a local minimum and the following local maximum. Which is a characteristic of all waves? All kinds […]

Is Sparkling Ice really 0 calories? Sparkling ICE is a zero calorie beverage sweetened with sucralose and made with natural flavors, vitamins, antioxidants and lightly carbonated spring water. How many calories is ice drink? Why is Sparkling Ice® now 5 calories? Beginning January 1, 2020, the U.S. Food & Drug Administration’s new Nutrition Facts Panel […]

What is the equation for potential energy quizlet? The equation for determining gravitational potential energy is PEg=mgh. How are potential and kinetic energy related quizlet? What is the difference between kinetic and potential energy? Kinetic energy is the energy of motion, and potential energy is an object’s energy due to its position or shape. What […]

What are two examples of the Doppler effect? The drop in pitch of ambulance sirens as they pass by and the shift in red light are common examples of the Doppler Effect. Edwin Hubble made the discovery that the universe expands as a consequence of the Doppler Effect. Where is the Doppler effect used? Doppler […]
