How many faces edges vertices does a dodecahedron have?
Faces- 20 Edges- 30 Vertices- 12
When prim algorithm fail?
When there are directed edges in the graph, as it is impossible to move back from B to A when the edges are directed.
How many faces edges vertices does a octahedron have?
It has 8 faces, 6 Vertices, and 12 edges * * * * * That is one configuration. An octahedron can also be a heptagonal pyramid which has 8 faces, 8 vertices and 14 edges.
How many faces vertices and edges does a hexagon have?
Pretty simple really: Vertices are corners and edges are boundaries so, a hexagon has six of each.
Requirements of joints in rigid pavement?
to resist the slab from bending moment at the edges and stop moment of the edges when the vehicles moves the approaching direction
Why is there only tiles on the bottom of the space shuttle?
There are tiles on the entire space shuttle. Every square inch is covered in tiles. The nose, bottom and leading edges of the space shuttle have black tiles while the rest of the space shuttle has white tiles. The nose leading edges and the bottom of the shuttle are the portions of the shuttle that get the most friction/heat from the atmosphere during re-entry.
How hot does a space shuttle get when re-enters earths atmosphere?
The leading edges of the Space Shuttle's wings get to almost 3000 deg F during a normal reentry into earth's atmosphere.
How many edges does a octagonal pyramid has?
16 edges- the edges of the base, and the edges leading to the point of the pyramid.
Why does the space shuttle fly backwards on r-entry?
No, it re-enters front first and slows using air breaking, protected by the heat proof tiles on its leading edges, nose and under surfaces.
How hot does the space shuttle get on reentry?
The leading edges of the Shuttle, which get hottest during reentry, are protected by panels made of reinforced carbon-carbon (RCC) that are fixed to the vessel's structural skeleton by floating joints to allow for differences in thermal expansion. The RCC panels can tolerate a maximum temperature of 1,630°C.
What pyramid has 36 edges?
It is an enneadecagon pyramid as it has 18 edges on the bottom and 18 leading up to the top vertex.
What is the highest termperature composite material?
The carbon-carbon composite material used for the nose and leading edges of the wings on the space shuttle is probably the composite material designed to withstand the highest temperatures. This material is able to retain its mechanical properties at temperatures of 2000ºC.
What is leading edges on an airplane?
Curved front of the wings or tail surfaces.
What is a guitar binding?
the guitar binding is the white or black line going around the edges of the guitar. It is traditionally a different color from the wood or finish of the guitar and is made of either wood, plastics, or in some cases just painted on.
What type of turtle red and black skin?
It could be a painted turtle. The Western Painted Turtle has no red stripes that I could see, but has a red pattern at the edge of the shell and the bottom of the shell(plastron) is pink with a large, dark design extending to the edges. Hope this helps
How many edges does 3 dimensional pyramid have?
8 Four edges on the square base and then four more leading up from each corner to the apex.
Why the trailing edges of control surfaces are sharper than the leading edges?
The trailing edge is where the air flow comes together. The leading edge is where the air is diverted to produce the low pressure (top) and high pressure (bottom) to create lift.
