The original model Famicom featured two game controllers, both of which were hardwired to the back of the console. The second controller lacked the START and SELECT buttons, but featured a small microphone. Relatively few games made use of this feature. The earliest produced Famicom units initially had square A and B buttons. This was changed to the circular designs because of the square buttons being caught in the controller casing when pressed down and glitches within the hardware causing the system to freeze occasionally while playing a game.

What shape did the A and B buttons eventually become?
Answer: circular

The amount of signal received from a distant transmission source is essentially geometric in nature due to the inverse square law, and this leads to the concept of effective area. This measures the performance of an antenna by comparing the amount of power it generates to the amount of power in the original signal, measured in terms of the signal's power density in Watts per square metre. A half-wave dipole has an effective area of 0.13 2. If more performance is needed, one cannot simply make the antenna larger. Although this would intercept more energy from the signal, due to the considerations above, it would decrease the output significantly due to it moving away from the resonant length. In roles where higher performance is needed, designers often use multiple elements combined together.

What accounts for the geometry involved in the use of an antenna?
Answer: inverse square law

When the British invaded the harbour town in 1744[verification needed], the town's architectural buildings were destroyed[verification needed]. Subsequently, new structures were built in the town around the harbour area[verification needed] and the Swedes had also further added to the architectural beauty of the town in 1785 with more buildings, when they had occupied the town. Earlier to their occupation, the port was known as "Carenage". The Swedes renamed it as Gustavia in honour of their king Gustav III. It was then their prime trading center. The port maintained a neutral stance since the Caribbean war was on in the 18th century. They used it as trading post of contraband and the city of Gustavia prospered but this prosperity was short lived.

What year did the Swedes add more buildings to the harbour town?
Answer:
1785
