Does the atomic radius increase from left to right? Atomic radius is determined as the distance between the nuclei of two identical atoms bonded together. The atomic radius of atoms generally decreases from left to right across a period. The atomic radius of atoms generally increases from top to bottom within a group. What is […]

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 is meant by one dimensional elastic collision? Two identical objects (such as billiard balls) have a one-dimensional collision in which one is initially motionless. After the collision, the moving object is stationary and the other moves with the same speed as the other originally had. Show that both momentum and kinetic energy are conserved. […]

Which type battery is best? Lithium-ion batteries What kind of batteries are least expensive? The most economical Li-ion battery in terms of cost-to-energy ratio is the cylindrical 18650 cell. Where is the cheapest place to buy batteries? For the best overall prices, consider shopping at one of these top five places to buy cheap batteries: […]

How many miles will be traveled by at least 80 percent of the trucks? 39,900 miles How many miles can a trucker drive in a week? 3,000 miles How long can a truck driver drive before resting? Drivers can drive for up to 11 hours during the duty period. However, after driving for eight hours, […]

What triggers sweating? Sweating is your body’s mechanism to cool itself. Your nervous system automatically triggers your sweat glands when your body temperature rises. Sweating also normally occurs, especially on your palms, when you’re nervous. The most common form of hyperhidrosis is called primary focal (essential) hyperhidrosis. Where do humans sweat the most? The human […]

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 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 […]

Is it more energy efficient to boil water? An electric stove requires more energy and time to heat up, thus it takes longer to heat the water inside the kettle. However, an electric stove is more efficient in delivering energy to the kettle. Using boiling water and vinegar removes mineral deposits that reduce its energy […]

What is the primary use of the following agar slant agar deep broth? What is the primary use of slants? Provides a solid growth area that is easier to store. What is the primary use of deeps? Used to grow bacteria that needs less oxygen. What are agar deep used for? Agar deeps are used […]
