...air and their equations of motion An object in motion througha gaseous atmosphere is subject to resistance by the surrounding media. Under quasistatic conditions (i.e. no turbulence), the force inflicted by the media on the object is always acting in the direction directly opposed to the objects instantaneous velocity vector. The magnitude of that force depends on the objects velocity, increasing with increasing velocity. The underlying law is derived empirically rather than based on theory. For most situations, simple approximations usually suffice; the simplest one of them is the assumption of direct proportionality between velocity... as object mass increases (see tables at the end of paper). This proves air resistance has a significant effect for lighter objects. Only the value for lors is close to that predicted by equation (3). Numerical solution of equation (16) was performed in the attached excel file, on the sheet named “Determining p“, where the relevant crossing points are highlighted in color. To determine p, linear interpolation was used, following the formula p = , (17) where D0, D1 are the differences between left side and right side of equation (16), for the corresponding values p1, p0 close to the crossing point. Results are summarized in table 7. For lors, p could not be determined because it is too close to 0... _ ...

Lack of enough friction between the ground and the feet soles results in having a hard time while walking on slippery grounds. The big question is why the big horn sheep does not fall while climbing the wet rocks? The bighorn sheep makes its initial contact with a rock or any other surface using its rear section found in its cloven hoof, which is the region where the two hoof digits join.

One definition for violence has been that it “entails acts of physical coercion or their threat” (Jacobs, Jacobson and Marchbank, 2000, p.2). Here, the connection between gender and violence can be established if gender relations is understood as a discourse “signifying relationships of power” (Jacobs, Jacobson and Marchbank, 2000, p.3).

Glider 2 Prototype A glider is a light aircraft designed to fly on air without the use of engines. The glider is capable of flying for long periods while just being controlled. Gliders are developed through the early pre-modern flights such as the kites and parachutes. Moreover, gliders were mostly used for sporting activities and it has now become the major application. There have been a great improvement in the performance of gliders and currently they can fly several thousand kilometers in a...

...air resistance. Whenever the capacitor is by-passed by an emitter, and capacitance of the coupled capacitor is large in regards to the AC frequency signal, the capacitors would be approximated as a circuit that is short (BS EN 1097-2, 1998). Whenever the input signal or voltage is increased the output voltage and the signal would be further vary around the dc bias point that has been established (Highways Agency , 2009). This effect would continue up to when the limiting condition of the voltage... ? Determination of resistance to fragmentation by the LOS Angeles Test. Determination of resistance to fragmentation by the LOS Angeles Test. Aim The aim of this experiment was to find out the aggregate...

...Resistance of Bacteria to Antibiotics Introduction Antibiotics fight against bacteria and microbes, which cause infectious diseases in humans. The invention of antimicrobial chemotherapy has prolonged human longevity. This discovery is a landmark event of the medical sciences in the Twentieth Century. However, over a period of time, these microbes and bacteria have become immune to antibiotic medicines, and this poses a serious threat to the public health (Todar). Antibiotics inhibit the growth of bacteria in humans, animals and plants. Bacteria and microbes cause infectious diseases, and antibiotics can be used against diseases caused by bacteria and viruses. For instance... of the of the of the The...

...air resistance during flight. In this respect, it has a protruding nose with smooth, curved body surfaces. Yet another aerodynamic feature of the x3 is its flat profile which significantly helps in the reduction of drag and vibration during flight (Dubois, 2010). In conclusion, the x3 is a craft that has been effectively designed to overcome many limitations of the conventional helicopters... Aerodynamics on the Eurocopter x3 Helicopter Several helicopter models have been produced by various companies with engine driven rotors supplying the power to lift and move horizontally. Helicopters are naturally designed to hover, and take off and land vertically. They can also fly laterally, backwards and...

...resistance largely ended. Inadditiontotheintensity of the bombardment, the air campaign was also notable for its use of a new generation of precision-guided bombs and aerial reconnaissance aircraft that provided battlefield commanders with real-time images of Iraqi positions. Precision-guided bombs used in the conflict included Joint Direct Attack Munitions (JDAM), conventional bombs outfitted with a device that uses the global positioning system to home in on targets. Despite the improved precision of U.S. weaponry, errant missiles landed in the neighbouring... Introduction Air power has been increasingly attaining the status of the most primary option to respond to the bulk of the global crises, which ...
