This applies equally to the Earth rotating around the axis of the Sun and the center of the Milky Way Galaxy. This view of Earth comes from NASA's Moderate Resolution Imaging Spectroradiometer aboard the Terra satellite. In physics, the angular velocity is a vector quantity which specifies the angular speed of an object and the axis about which the object is rotating.
What sarin is. 1  Sarin is a human-made chemical warfare agent classified as a nerve agent. 2  Sarin originally was developed in 1938 in Germany as a pesticide. 3  Sarin is a clear, colorless, and tasteless liquid that has no odor in its pure form. 4  Sarin is also known as GB. Nerve agents are the most toxic and rapidly acting of the known chemical warfare agents. 2  They are similar to certain kinds of insecticides (insect killers) called organophosphates in terms of how they work and what kind of harmful effects they cause.
Pepsin is an enzyme whose zymogen (pepsinogen) is released by the chief cells in the stomach and that degrades food proteins into peptides.epsin is a digestive protease, a member of the aspartate protease family. Pepsin is one of three principal protein-degrading, or proteolytic, enzymes in the digestive system, the other two being chymotrypsin and trypsin. The three enzymes were among the first to be isolated in crystalline form.
