The white flag is an internationally recognized protective sign of truce or ceasefire, and for negotiation. It is also used to symbolize surrender, since it is often the weaker party that requests negotiation. It is also flown on ships serving as cartels.

A charged black hole is a black hole that possesses electric charge. Since the electromagnetic repulsion in compressing an electrically charged mass is dramatically greater than the gravitational attraction (by about 40 orders of magnitude), it is not expected that black holes with a significant electric charge will be formed in nature.
Scalable Vector Graphics ( SVG) is an XML -based vector image format for defining two-dimensional graphics, having support for interactivity and animation.

If that doesn't fix the problem, try these steps and attempt to sign in after each one: Try signing into a different sign-in page, like our.
The no-hair theorem (which is a hypothesis) states that all stationary black hole solutions of the Einstein–Maxwell equations of gravitation and electromagnetism in general relativity can be completely characterized by only three independent externally observable classical parameters: mass, electric charge, and angular momentum.

Stellar classification. In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with spectral lines.
