Which type of wave can travel in a vacuum? Electromagnetic waves How big is a 4 foot wave? The ‘Hawaiian’ system is a well established alternative to measuring the face height and tends to equate consistently to about half the face height. So a 4ft Hawaiian wave is 8ft on the face, or a couple […]
What traits are dominant and recessive?
What traits are dominant and recessive? The traits due to dominant alleles are always observed, even when a recessive allele is present. Traits due to recessive alleles are only observed when two recessive alleles are present. For example, the allele for widow’s peak is dominant and the allele for straight hairline is recessive. How do […]
What is rapidly renewable materials?
What is rapidly renewable materials? The USGBC defines “rapidly renewable” as a material that’s able to regenerate itself in 10 years or less. That includes bio-based products made from plants harvested on a 10-year (or shorter) cycle. Rapidly renewable materials include linseed, straw, cotton, wheat, sunflowers, natural rubber, bamboo, and cork. Is Bamboo rapidly renewable? […]
How do you make an RCC building earthquake resistant?
How do you make an RCC building earthquake resistant? Another method to reduce failure during earthquakes is to design a strong core shear wall in seven to 20 storey RCC structures. Typically, this is designed in the elevator area. If the shear wall is designed as per relevant code, it can provide necessary stiffness to […]
What happens to the resistivity of wire if it is stretched?
What happens to the resistivity of wire if it is stretched? The resistance of a wire is inversely proportional to its area and directly proportional to its length. When the length is tripled then resistance will also become three times. If The wire is stretched 3 times the original length, the cross-section of the wire […]
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 […]
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 lowest passing grade?
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 […]
