1)There is an emitter that can send two type of signal.It can emmit a information in a packet of 4 signals.Howmany different type of information can be send by this emmitter?suppose A and B are two signals.One of the example information is given below-(please refer to FIG-1 in image )
a)2 b)4 C)6 D)8
2)JAGADAMBA has printed an Quadrilateral pyramid structure with the help of a 3D printer.Then to make it smaller he started to slice it parallel to one of the triangular side .what would be the shape of leftover part?(PLEASE refer TO FIG-2 for DIAGRAM in image)
a)triangular pyramid b)truncated prism c)parallelpide d) right traingular prism
3)A micro controller worrks as a small brain which can directed by computer codes .RAM has developed a microcontroller which has 8 pins as shown in figure.(please refer FIG-3 in image).Corresponding codes are given in the table( also refer that fig-3 in image).Black pin always give voltage = 0 V and white pin always provide-5 V :: Controlelr read the instructions from up to down .Sample code for running a motor:QUESTION-which of the following is correct regarding the connection of LED for this project?"
A)",Small-Black Long Leg-Yellow"
b)Small Leg-Blue Long Leg-White
c)Small-Yellow Long Leg-Blue
d)ALL of above
pls answer asap sirr

Expert Answer
(1) In the packet there are four signals each of type 2, hence possible number of signals = 2×2×2×2 = 16
(2) The structure, which is a pyramid on quadrilateral base is sliced parallel to the triangular side.
Hence resulting structure also pyramid on quadrilateral base
(3) To light diode, long leg should be given +ve voltage and small leg is given 0 V.
This can be achieved by the relevant code. Hence (a), (b) and (c) all are correct
