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 […]

What is E in drift velocity?
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 […]
What is the magnitude of the horizontal component of the velocity?
What is the magnitude of the horizontal component of the velocity? The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a […]
What is the current EPA standard for PM 10 for daily exposure?
What is the current EPA standard for PM 10 for daily exposure? EPA is retaining the existing 24-hour primary standard for coarse particles (PM10), with its level of 150 µg/m3. An area meets the 24-hour PM10 standard if it does not exceed the 150 µg/m3 level more than once per year on average over a […]
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 […]
Why do hurricanes never hit California?
Why do hurricanes never hit California? In short, wind direction and cold water are the main reasons we don’t see hurricanes in California. Tropical storms and tropical storms that become hurricanes need warm water to form. The area of 15 degrees north latitude is prime real estate for storms over open water. Is a hurricane […]
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 […]
