that the Universe sprang into existence from a singularity -- a term physicists use to describe regions of space that defy the laws of physics. We know very little about singularities‚ but we believe that others probably exist in the cores of black holes. The second part of the question‚ as to what existed before the Big Bang‚ has scientists baffled. By definition‚ nothing existed prior to the beginning‚ but that fact creates more questions than answers. For instance‚ if nothing existed prior to the

MORTISER AND TENONER 8.1 Overview The mortise and tenon joint normally used to make the connection between the ends of two pieces of wood that have holes and put the glue to strengthen the grip of the mortise and tenon. Mortise and tenon has long existed for thousands of years used in the work produced wood products. In using this joinery is commonly used in the manufacture of furniture such as chairs and tables. There also are used in the manufacture of infrastructure and income staircase made

Aspect 1: Focused problem: Investigate the relationship between the surface area of a circular hole and the time water takes to drain through it. Variables: Independent: Surface area of the hole Dependent: Time water takes to drain Fixed: Amount of Water Container Environmental Conditions Aspect 2: Control of the Variables The independent variable in this case is the surface area of the hole‚ and the dependant will be the time water takes to drain through it‚ as hypothetically it will

Ou-t” the hole symbolizes an easy solution for a big problem. People used this hole to dump their waste‚ and fears into it. They used it to dispose unwanted materials‚ and at the same time to bring money into the city by charging others to dump their waste into it. The hole also symbolizes the people’s ignorance as well‚ people do not fully understand what this big dark gaping space is‚ and that it could harm the Earth in many possible ways‚ yet they still use it for their own good. The hole is a positive

number of machine tools producing round and taper holes. But many engineering components require square and non-circular holes. At present square and other non holes are produced using CNC machines or spark erosion or slotting machines. But there is no quality machine tool to produce square and polygon holes at minimum cost. Thus we made an attempt to design and fabricate an attachment for drilling machine which would produce square and polygon holes much more easily than the current method. This

You will need to design an 18 hole course to fit within 42 acres‚ an area of land purchased by the golf club. The shape of the 42 acres is not a constraint‚ as the land can be in any configuration across a larger privately owned title. A golfing hole is a section of a golf course. Each hole comprises an area called the tee from which golfers start each hole. Golfers strike the ball from the tee and are aiming to move the ball towards a cup at the other end of the hole. The cup is located somewhere
