One purpose of the dual ignition system on an aircraft engine is to provide for?

2 answers:

8 0

Answer: Redundancy

Explanation:
An aircraft is a system that cannot tolerate faults or errors because the consequences can be fatal.
Therefore the ignition system is an excellent design candidate for redundancy.
Redundancy ensures that if the primary ignition system fails, a reliable backup ignition system will be available.

Another example of redundancy is the use of electric power generators in a hospital. They back up the primary electricity power supply because failure of electric power during surgery cannot be tolerated.

It is done to provide for better engine performance. It is important for two main reasons. One is that if one ignition system fails the other can for a time take care of it and hold its ground until you land or fix it. Another is that it is used for more efficient consumption of fuel and air which makes the engine work better.

What is an example of technology that helps support the idea of continental drift.

docker41 [41]

I don't know technology, but using Satellite images, we are able to see that the continents once fitted into one 'jigsaw'. This shows that the continents must have drifted to its original place. Furthermore, Geothermal stations have pointed out convection currents in the Earth's mantle has caused the movement of crusts.

A personal identification number (PIN) that opens a certain lock consists of a sequence of 3 different digits from 0 through 9,

Elan Coil [88]

Answer:

<u>720</u> possible PIN can be generated.

Explanation:

To calculate different number of orders of digits to create password and PIN, we calculate permutation.

Permutation is a term that means the number of methods or ways in which different numbers, alphabets, characters and objects can arranged or organized. To calculate the permutation following formula will be used:

nPr = n!/(n-r)!

there P is permutation, n is number of digits that need to be organize, r is the size of subset (Number of digits a password contains)

So in question we need to calculate

P=?

where

n= 10 (0-9 means total 10 digits)

r= 3 (PIN Consist of three digits)

So by using formula

10P3 = 10!/(10-3)!

=10!/7!

= 10x9x8x7!/7!

= 10x9x8

= 720

⦁ Consider transferring an enormous file of L bytes from Host A to Host B. Assume an MSS of 536 bytes. ⦁ What is the maximum val

timurjin [86]

Answer:

a) There are approximately 2^32 = 4,294,967,296 possible number of the sequence. This number of the sequence does not increase by one with every number of sequences but by byte number of data transferred. Therefore, the MSS size is insignificant. Thus, it can be inferred that the maximum L value is representable by 2^32 ≈ 4.19 Gbytes.

b) ceil(2^32 / 536) = 8,012,999

The segment number is 66 bytes of header joined to every segment to get a cumulative sum of 528,857,934 bytes of header. Therefore, overall number of bytes sent will be 2^32 + 528,857,934 = 4.824 × 10^9 bytes. Thus, we can conclude that the total time taken to send the file will be 249 seconds over a 155~Mbps link.

Explanation:

b) ceil(2^32 / 536) = 8,012,999
