Event horizon:
The radius which a spherical mass has to be compressed to transform it in a black hole, or the radius at which space and time switch responsibilities. Once inside the event horizon, it is impossible fundamentally to escape to the outside. In addition, nothing can prevent a particle from hitting the singularity within extremely short amount of proper time once it has entered the horizon. In this case, the event horizon is a "point of no return."
For generalized black holes (in geometrized units) the radius of the event horizon, r, is
r = m + (m2 - q2 - s/m2)1/2,
Where m refers to the mass of the hole, q refers to its electric charge, and s refer to its angular momentum.
Subtracting 2 Vectors This is where things obtain a bit more interesting. What we required to note here is in which in Physics a negative sign simply means "in the opposite dir

The energy possessed by a object by virtue of its position or its configuration is called its potential energy. Concept of potential energy is valid only in conservative field.
In 1.0s, 5.0x10^23 nitrogen molecules strike an area of8.0cm^2 at a speed of 300m/s. What is the pressure? (mass of one nitrogen molecule = 4.68x10^-26 kg.) I believe I should use
Cosmological redshift An effect where light emitted through a distant source seems redshifted due to the expansion of spacetime itself.

It is an instrument used to detect small current passing by it by showing deflection. Galvanometers are of dissimilar types e.g. moving coil galvanometer, moving magnet galvanomete
