What is E in drift velocity? In physics a drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field. In general, an electron in a conductor will propagate randomly at the Fermi velocity, resulting in an average velocity of zero. Why is electron drift […]
Can I take a picture of something and Google it?
Can I take a picture of something and Google it? The Google Goggles app is an image-recognition mobile app that uses visual search technology to identify objects through a mobile device’s camera. Users can take a photo of a physical object, and Google searches and retrieves information about the image. How do I reverse search […]
Which type of wave can travel in a vacuum?
Are tongue twisters good for speech?
Are tongue twisters good for speech? Tongue twisters are a great way to practice and improve pronunciation and fluency. They can also help to improve accents by using alliteration, which is the repetition of one sound. They’re not just for kids, but are also used by actors, politicians, and public speakers who want to sound […]
What is the formula for displacement?
What is the formula for displacement? Displacement (s) of an object equals, velocity (u) times time (t), plus ½ times acceleration (a) times time squared (t2). What is the area under displacement time graph? Important: The area between a velocity-time graph and the `time’ axis gives the displacement of the object. The slope is the […]
What are the three types of molecular models?
What are the three types of molecular models? Molecular models fall into three basic categories: ball-and-stick, skeletal, and space-filling. What are four types of molecular models? On this page: Ball and spoke models. Space-filling models. Crystal lattice models. What is the purpose of molecular models? Molecular modeling is rapidly growing according to its applications in […]
What are two components of no load current in transformer?
What are two components of no load current in transformer? No load current of large power transformers consists of active and reactive component. Active component covers hysteresis and eddy current losses in the core. Reactive component (usually called magnetizing current) creates magnetic field / magnetic flux and lags the voltage by 90°. Why no load […]
Which state of matter has the greatest amount of kinetic energy?
Which state of matter has the greatest amount of kinetic energy? Energy and State of Matter Particles has the highest kinetic energy when they are in the gaseous state. Kinetic energy is related to heat (also called thermal energy). Raising the temperature results in an increase of its kinetic energy. What molecule has the most […]
What are the 5 levels of the Physical Activity Pyramid?

Moderate physical activity is the first step in the Physical Activity Pyramid, and it should be performed daily or nearly every day. Vigorous Aerobics. Vigorous Sport and Recreation. Muscle Fitness Exercises. Flexibility Exercises. […]
Can we see water vapor?
Can we see water vapor? Gaseous water, or water vapor, isn’t something you can see, but it’s part of the air around you. Under normal circumstances, water vapor enters the atmosphere through evaporation and leaves by condensation (rain, snow, etc.). Water vapor also enters the atmosphere by a process called sublimation. Does water vapor contain […]
