Calculate the air temperature and pressure at the stagnation
Calculate the air temperature and pressure at the stagnation point right in front of a meteorite entering the atmosphere (-50 °C, 50 kPa) with a velocity of 2000 m/s. Do this assuming air is incompressible at the given state.

A charge of +q is located at the origin, while an identical charge is located on the x axis at x = 0.46 m. A third charge of +3q is located on the x axis at such a place that the net electrostatic force on the charge at the origin doubles, its dir
You drive on the highway with 120 km/h on a day with 17°C, 100 kPa atmosphere. When you put your hand out of the window flat against the wind you feel the force from the air stagnating, i.e. it comes to relative zero velocity on your skin.
