NASA has an online applet to show how the lift equation impacts the flight of aircraft. This is based off a lift coefficient calculator, and you can use it to set different values of velocity, angle that the airborne object takes with respect to the ground and the surface area that the o...
At this point, the interpretation ofp_0andT_0is apparent: they allow us to scale the pressure and temperature to dimensionless quantities. From this point onward we will use subscripts in italicp_{in},p_{out}, andT_{IC}to denote the dimensionless\frac{p_\text {in}}{p_0},\frac{p_...
In 1974, physicist Stephen Hawking put forward a theoretical concept that became known as "Hawking radiation." In simple terms, it refers to particles being created at the event horizon of a black hole. These particles are thought to be caused by the immense gravitational pull of black holes ...

Guided by theoretical considerations, we also develop a non-linear voltage sweep and demonstrate, with molecular dynamics simulations, that it can charge a nanopore even faster than the corresponding optimized linear sweep. For discharging we find, with simulations and in experiments, that if we ...
A mass attached to a vertical spring has position function given by s(t)=4sin(4t) where t is measured in seconds and s in inches. a) Find the velocity at time t=1. b) Find the acceleration at time Use a computer algebra system to find the mass, center of mass, and moments of ...
material is flowing towards and away from the black hole. They found Sgr A* is spinning with an angular velocity — the number of revolutions per second — that is about 60% of the maximum possible value, a limit set by material not being able to travel faster than the speed of light....
Urbanization and climate change are contributing to severe flooding globally, damaging infrastructure, disrupting economies, and undermining human well-being. Approaches to make cities more resilient to floods are emerging, notably with the design of flood-resilient structures, but relatively little is kno...
Economic equilibrium is considered a theoretical concept, which means it's hard to achieve. That's because the variables are always changing and there are always unpredictable factors at play that can influence where the economy is headed. In order to achieve it, the forces at work in the eco...
