BUOYANCY PHYSICS Student: Instructor: Criteria : Design Introduction The purpose of this experiment to find the effect of temperature on buoyancy . Backround Information Buoyancy (also known as the buoyant force) is the force exerted on an object that is wholly or partly immersed in a fluid. The symbol for the magnitude of buoyancy is B or FB As a vector it must be stated with both magnitude and direction. Buoyancy acts upward for the kind of situations encountered in everyday experience

Energy: the ability to do work. Work= force x displacement. Power=energy/time Power is measured in watts or horsepower. Joules/sec=watts 1hp=746w=1kw Basal metabolic rate 2000kcal/day= 100w Batteries store energy in chemical form. They release energy by pumping electrons’ through wires from the minus pole to the plus pole. Devices inbetween convert this energy to another form‚ Efficieny- e.motor=85%‚ combustion= 20% Hydrogen is not a source of energy but a means of transportation Types of energy:

(a)Ferromagnetic materials: Ferromagnetic materials have a large‚ positive susceptibility to an external magnetic field. They exhibit a strong attraction to magnetic fields and are able to retain their magnetic properties after the external field has been removed. Ferromagnetic materials have some unpaired electrons so their atoms have a net magnetic moment. They get their strong magnetic properties due to the presence of magnetic domains. In these domains‚ large numbers of atom’s moments (1012

The Puzzle of Emergence The puzzle of emergence is a very controversial and complex‚ scientific puzzle. This concept of emergence has been a baffling topic that has stumped many scientists and philosophers throughout the past centuries. George Henry Lewis was the first theorist to give wisdom to this puzzle in the late 1800s and so have many other theorists after this puzzle was first proposed. The term emergence can be defined differently in both a scientific or philosophical situation. It comes
