What is the thinnest liquid? Thanks to the “super material” graphene, a team of researchers managed to create one of the world’s thinnest layers of liquid. There’s now a new understanding of the word “wet” thanks to physicists who created the thinnest film of liquid ever. What is a viscous sauce? A sauce that runs […]

When a capacitor is connected to a battery? If an uncharged capacitor C is connected to a battery of potential V, then a transient current flows as the capacitor plates get charged. The flow of current from the battery stops as soon as the charge Q on the positive plate reaches the value Q = […]

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 = […]

What two factors can make an object stable? The stability of an object is dependent on two factors: The base width of the object. The center of gravity. What are structures for Grade 3? A structure is a solid that has a shape, size, and purpose. It holds a load. Example: A tennis shoe is […]

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 […]

Was Rayon a real person? So the story being shopped as true is, at its heart, a fiction. The movie Woodruff is a hyper heterosexual and bigot, and his heroism stems both from creating the Dallas Buyers Club and being taught tolerance by Leto’s Rayon. And Rayon is an entirely fabricated person. Was Suicide Squad […]

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. […]

Does speed of sound depend on pitch? The speed of sound is dependent on temperature. As the temperature of the air increases, the speed of sound in air increases. Frequency of sound and pitch are related. The higher the pitch, the greater the frequency. What is the highest possible frequency of sound? That’s about the […]

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 […]

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 […]
