effectors of the drop time of a parachute, which can be proven through Newton’s second law, F=ma (Force=mass*acceleration). Rearranged, this gives a=F/m, where acceleration can also be gravity, if falling down. Another equation is a=v/t (acceleration=velocity/time) and a=(√2s)/t (acceleration=(sqrt2*distance)/time). The research question that this investigation will explore is: How is the drop time of a parachute affected by its mass? Photo 1: Parachute…

benefits of saving certain amount of time outweigh the costs of potentially getting caught and paying a fine, motorist is likely to exceed the speed limit. Some motorists exceed the speed limit because they seek the thrill of travelling at high velocities. If the motorist values thrill greater than their life, driver may decide to exceed the speed…

energy stored in battery bank before the rest power inverted again from DC to AC source. Fig(1) The power energy available in wind can be expressed in mathematical equation as: = Air density (approx.1.225 kg/m3 at sea level) = Velocity of wind (m/s) = Area through which the wind passes normally (m2) This cubic relationship mean the power availability is extremely sensitive to wind speed The power extracted from wind energy is just a fraction of this equation.…

and Rx (or surrounding objects causing e.g. reflection) causes random frequency modulation. Figure 11 Multipath propagation Each multipath component has different Doppler shift. The Doppler shift can be calculated by using: fd=Vλcosα V is the velocity of the…

Performance Measurement at DELL: Performance measurement is an important parameter which quantitatively gives information about our process, product and services. This helps us to know whether we are moving towards mission and vision or deviating from our core goals. At present big corporations don’t want to indulge into performance measurement system, instead they put their whole focus on achieving operational excellence. But Dell is very focus on measuring its supply chain efficiency on…

epidermis and dermis are penetrated throughout by free nerve endings of Aδ and C fibres. Aδ-fibres typically exhibit medium-sized cell bodies, thinly myelinated axons and intermediate conduction velocities (9). C-fibres on the other hand exhibit small cell bodies, no myelin sheath and slow conduction velocities (9). Both types of fibres aid in thermotransduction (9). Specific thermosensitive channels are believed to be associated with these free nerve endings, working in concert to orchestrate…
