Radiation.
Such a speed is technically called the speed of light, but it could also be defined as ~Mach 1000000.
Scattering. The location inside the Earth where an earthquake begins is called the focus.
The phenomenon where light waves travel in straight lines is called rectilinear propagation. This means that light travels in a straight path unless it encounters a medium that causes it to change direction.
Light travels at 300,000 km/sec. (in a vacuum). That is enough to go 7 1/2 times around the Earth in a second (but note that light has a natural tendency to go in a straight line).
An isobaric process is a thermodynamic process that occurs at a constant pressure. This means that the system is allowed to exchange heat with its surroundings but the pressure remains the same throughout the process. In an isobaric process, the work done is determined by the change in volume of the system.
