Using simply a capacitor and a resistor, the timing interval can be adjusted and so can be utilized for quite a few applications together with timers, clocks, switches, safety alarms and tone mills. An thought for an EEI could be to test the accuracy of the timing circuit.

So when you could measure the stress within the string with a force sensor and capture the information with a laboratory interface, a plot of drive vs. time should give you the peaks that you need. For a typical hand-held torch working at say 6V DC, the combination of frequencies should be such that the color appears white to the eyes. At low voltages – and therefore low filament temperatures – the filament glows a boring pink, however because the voltage is increased, the temperature additionally increases. This elevated temperature not only produces “whiter” mild as … Read More

One attention-grabbing method I’ve seen is to drop a dice of steel into water in a polystyrene cup and measure the speed of heating of the water. Doesn’t the rate of warming slow down as the difference in temperature will get much less? An attention-grabbing utility of thermal conductivity testing is proven below. Here they’re attempting to get an accurate worth of the existing soil situations for a geothermal project. When an asteroid hits the ocean at a typical speed of kmh-1 there is a gigantic explosion.

Why Can We Not Record Black And White As Colours In Physics?

The asteroid and water vaporize and leave an enormous crater – typically 20 instances the diameter of the asteroid . The water rushes back in, overshoots to create a mountain of water at the middle and this spreads out as an enormous wave – a tsunami. … Read More

Song Bac Toh is now with Cisco Systems within the US and he gave me some clues about his experiment – which I even have tried, succesfully. The attenuation of sound in air is because of a number of components including viscous, thermal and rotational losses (∝f2); and vibrational relaxation of gas molecules. The attenuation of sound is determined by temperature, water-vapour content material and frequency. A mirage is the place you see an object that is on the ground in the distance however it seems like it’s both floating above the bottom or reflected off the floor.

It is a result of the different densities of air above the floor brought on by heating . However an identical impact could be seen if you shine a laser right into a tank containing concentrated sugar solution on to which a layer of water has … Read More
