WebbDrag force FD is proportional to the square of the speed of the object. Mathematically, FD = 1 2CρAv2, where C is the drag coefficient, A is the area of the object facing the fluid, and ρ is the density of the fluid. Athletes as well as car designers seek to reduce the drag force to lower their race times ( Figure 6.29 ).

However, in such large-scale data centers, servers of different generations are installed gradually year by year, making the data center heterogeneous in computing capability and energy efficiency. …
WebbThere are plenty of experiments happening around the world every day which exhibit quantum effects. But the situation of course was quite different about 100 years ago or so when quantum physics was born. When people couldn't rely on such sophisticated techniques and methods, and manifestations of quantum physics were very, very subtle. Webb20 mars 2013 · Proportion and Ratio in Geometry and Classical Physics Historically, the pioneers of classical physics, from Galileo to Newton and Faraday, expressed physical relations as the proportionality of ratios of two or more kinds of quantities.
