What are the applications of Poynting Theorem? [31] Application of Poynting’s Theorem to electromagnetic energy transfer between the magnetosphere and ionosphere, based on observations of the perturbation Poynting vector Sp above the ionosphere, gives an accurate quantitative measure of this transfer in a spatially integrated sense. Why do we use Poynting Theorem? Poynting’s theorem is […]

What body type are models?
What body type are models? Catwalk models must be tall and slender, while glamour models are usually curvaceous. Alternative models need tattoos and piercings, while commercial models will do better with no body modifications. Is 5’7 tall enough for a model? It will be what sets you apart from other models in the industry. As […]

Why are there only 7 diatomic molecules?
Why are there only 7 diatomic molecules? Some sources will say there are five diatomic elements, rather than seven. This is because only five elements form stable diatomic molecules at standard temperature and pressure: the gases hydrogen, nitrogen, oxygen, fluorine, and chlorine. Hydrogen has one orbit ,so 2(1^2) is 2. How many diatomic molecules are […]
Is a rolling pin a wheel and axle?
Is a rolling pin a wheel and axle? Guide them to express these understandings: The rolling pin is a wheel and axle. When you push on the handles (the axle) the wheel turns and flattens out the dough. Challenge students to think of other common machines that have one wheel like the rolling pin. What […]
How can we find Valency of oxygen?
How can we find Valency of oxygen? If its Valence electrons are less than 4, then valency is equal to number of valence electrons and if it is more than 4 then valency is obtained by subtracting number of valence electrons from 8. Atomic Number of oxygen is 8. So, electronic Configuration of oxygen= 2, […]
What kind of tectonic boundary do we find near the Pinnacles National Park in Northern California?
What kind of tectonic boundary do we find near the Pinnacles National Park in Northern California? Located near the boundary of the Pacific Plate and the North American Plate, Pinnacles National Park is an excellent example of tectonic plate movement. The Pinnacles Rocks are believed to have originated in the Neenach Volcano, near present-day Lancaster, […]
What is molecule and its types?
What is molecule and its types? A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more […]
How can your ear determine where sound is coming from?
How can your ear determine where sound is coming from? Humans use two important cues to help determine where a sound is coming from. These cues are: (1) which ear the sound hits first (known as interaural time differences), and (2) how loud the sound is when it reaches each ear (known as interaural intensity […]
