Write a Java 3D program to define and display an octahedron. The octahedron is one of the five Platonic solids. It has eight faces of triangles and six vertices: (0,0,1) (-1,0,0), (0,-1,0), (1,0,0), (0,1,0) (0,0,-1). Define the Octahedron class by extending the IndexedTriangleArray.

Asequential circuit contains a register of four flip-flops. initially a binary number n (0000 ≤ n ≤ 1100) is stored in the flip-flops. after a single clock pulse is applied to the circuit, the register should contain n + 0011. in other words, the function of the sequential circuit is to add 3 to the contents of a 4-bit register. design and implement this circuit using j-k flip-flops.

Light travels at a speed of 186,000 miles a second. the distance light travels in a year is 5,865,690,000,000 miles/year 5,865,695,000,000 miles/year 58,656,950,000,000 miles/year 6,789,000,0000 miles/year
