Where is the force on car 1 due to car 2, and is the time the force acts (the duration of the collision) intuitively, it seems obvious that the collision time is the same for both cars, but it is only true for objects traveling at ordinary speeds. • feminismis a complex notion that has vast differences in meaning and connotation for people spanning generations, ethnic identities, sexual orientations, social classes, nationality, and myriad identities.

Nature's encountering sea monsters does just that, as underwater cameraman bob cranston explores the remarkable world of marine creatures called cephalopods cephalopods include squids. Introduction coleoid cephalopods (squids, cuttlefishes, and octopuses) have been viewed as amazing illustrations of independent origins of complex neural and sensory structures, and possess the most highly centralized brains of any group of invertebrates ( akimushkin 1963 zullo and hochner 2011.

Squids have been reported to jump from the ocean and travel (measured horizontally) before re-entering the water (a) calculate the initial speed of the squid if it leaves the water at an angle of , assuming negligible lift from the air and negligible air resistance.
Squids belong to a particularly successful group of mollusks called the cephalopods, which have been around for about 500 million years some ancestors of modern-day squids had shells, such as the ammonites , which ruled the waves 400-65 million years ago. The vampire squid (vampyroteuthis infernalis, lit vampire squid from hell) is a small cephalopod found throughout temperate and tropical oceans in extreme deep sea conditions unique retractile sensory filaments justify the vampire squid's placement in its own order , vampyromorphida , as it shares similarities with both octopuses and squid. Bioluminescence is the production and emission of light by a living organism it is a form of chemiluminescence bioluminescence occurs widely in marine vertebrates and invertebrates , as well as in some fungi , microorganisms including some bioluminescent bacteria and terrestrial invertebrates such as fireflies.
An introduction to superconductivity and squids superconductivity was first discovered in 1911 in a sample of mercury metal whose resistance fell to zero at a temperature of four degrees above absolute zero.
