Can glass shards kill you? Popular belief for many centuries is that ground-up glass (i.e., glass broken into tiny fragments) can kill if swallowed. In fact, this is a myth, as it is largely ineffective. Why does a glass vessel break when it falls on a hard floor but does not break when it falls […]
Where do we use maximum power transfer theorem?
Where do we use maximum power transfer theorem? The Maximum Power Transfer theorem is used to find the load resistance for which there would be the maximum amount of power transfer from the source to the load. The maximum power transfer theorem is applied to both the DC and AC circuit. What is the difference […]

Why do carbon atoms have 6 electrons?
Why do carbon atoms have 6 electrons? The electrons like to be in separate shells/orbitals. Once one shell is full, the next electron that is added has to move to the next shell. So… for the element of CARBON, you already know that the atomic number tells you the number of electrons. That means there […]
What are the disadvantages of helicopter?
What are the disadvantages of helicopter? Drawbacks Of Helicopters Generally, helicopters have lower top speeds than airplanes, and are more complex to fly. Helicopters are also more complex mechanically, they need more maintenance which makes them more expensive to operate and maintain than airplanes. Should I fly fixed wing or helicopter? Fixed wing is the […]
What is the disadvantages of bridge rectifier?
What is the disadvantages of bridge rectifier? The main disadvantage of a bridge rectifier is that it needs four diodes, two of which conduct in alternate half-cycles. Because of this the total voltage drop in diodes becomes double of that in case of centre-tap rectifier, losses are increased and rectification efficiency is somewhat reduced. What […]
What are the disadvantages of bioethanol?
What are the disadvantages of bioethanol? What are the disadvantages of bioethanol? Debates surrounding food vs fuel: Some people are concerned that the popularity of biofuel is set to increase food prices across the globe. Efficiency: Biofuel fires tend not to get as hot as their wood-burning alternatives. Cost: Biofuel is often a little more […]
What triggers ammonium nitrate to explode?
What triggers ammonium nitrate to explode? Over time, the compound absorbs moisture, which can make the beads stick together into a huge rock, says Sella. When such a large quantity of compacted ammonium nitrate is exposed to intense heat — if, say, an accidental fire breaks out — it can trigger an explosion. Will ammonium […]
What is an example of linear perspective?
What is an example of linear perspective? Linear perspective allows artists to give the impression of depth by the property of parallel lines converging in the distance at infinity. An example of this would be standing on a straight road, looking down the road, and noticing the road narrows as it goes off in the […]
What time of day should you measure soil temperature?
What time of day should you measure soil temperature? morning Is the soil warmer than the air? “From early June on, the soil temperature is typically higher than the air temperature,” he explains. “It’s all about the sun hitting the soil surface.” 3. Scheeringa adds that as the ground warms up, some of the heat […]
