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 […]
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 wavelength of the first harmonic?
What is the wavelength of the first harmonic? For the first harmonic, the length of the string is equivalent to one-half of a wavelength. If the string is 1.2 meters long, then one-half of a wavelength is 1.2 meters long. The full wavelength is 2.4 meters long. What is a harmonic wave? A harmonic is […]
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 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 […]
Is magnesium water or fat soluble?

Is vitamin B water or fat soluble? Vitamins are classified as either fat soluble (vitamins A, D, E and K) or water soluble (vitamins B and C). This […]
What is difference between bacteria and archaea?
What is difference between bacteria and archaea? Difference in Cell structure Similar to bacteria, archaea do not have interior membranes but both have a cell wall and use flagella to swim. Archaea differ in the fact that their cell wall does not contain peptidoglycan and cell membrane uses ether linked lipids as opposed to ester […]
Why do atoms combine in a fixed ratio by weight?
Why do atoms combine in a fixed ratio by weight? One mole of water contains two moles of hydrogen and one mole of oxygen. And since a mole is a defined quantity and constant for every element, as a consequence, elements combine in a fixed ratio by weight. So, when two hydrogen atoms combine with […]
