Postulates of bohr:Elec electron in atom revolve around the nucleus in certain fix it circular parts called orbits
Orbit has fixed amount of energy so these are with sir also called energy levels these are which are denoted by 1 2 3 4 or klmn. As long as an electron revolt around the nucleus in a fixed orbit it does not EMIT or absorb energy so these are with sir also called as stationary orbits angular momentum of revolving electronics quantified and is an integral multiple of h by 2pie mvr equal...
FOB (Free on Board) is an important term used in international trade and export marketing. It refers to a pricing and delivery arrangement in which the seller is responsible for delivering the goods safely and loading them onto the ship at the specified port of shipment. The seller bears all costs such as packaging, inland transportation, and loading charges up to that point.
Once the goods are placed on board the ship, the ownership and risk are transferred from the seller to the buyer. After this...
1. World Space and Screen Space ▶World Space: The complete imaginary world of the film (everything that exists in the story, even if not shown). ▶Screen Space: Only what the audience actually sees on the screen. ▶Difference: World space is larger; screen space is limited to camera framing. ▶Importance: Helps filmmakers control what audience knows and sees. ▶Example: A character hears a sound off-screen → part of world space but not screen space.
2. Continuity (Space & Time) ▶Continuity
El Bienio Reformista (1931-1933) corresponde a la primera etapa de la II República española, durante la cual gobernó Manuel Azaña. Tras la aprobación de la Constitución de 1931, Niceto Alcalá Zamora fue elegido presidente de la República y encargó a Azaña la formación de gobiernoEste periodo se caracterizó por la aplicación de un amplio programa de reformas con el objetivo de modernizar el país. Sin embargo, estas reformas se llevaron a cabo en un contexto económico muy desfavorable,

Die Kapillarität
Kapillarwirkung:
- Adhäsionskraft - beschreibt die Anziehungskräfte zwischen Molekülen unterschiedlichen Typs;
- Kohäsionskraft - beschreibt die Anziehungskräfte zwischen Molekülen gleichen Typs.
A = Adhäsion: Anhangskraft zwischen verschiedenen Stoffen.
K = Kohäsion: Zusammenhangskraft innerhalb
