Your boss needs to recommend either the in-situ soil or the borrow material. Although you do not have much background on soil be
havior, what is your recommendation?
In providing your recommendation, you want to consider constructability issues (such as ease of compaction, moisture content). Without doing any additional tests, and based on your experience with soils, what compaction conditions would you suggest to achieve low permeability? What compaction conditions would you recommend to reduce soil expansion (swelling)?

Answer:
A) After 2.5 milliseconds
Explanation:
Given that :
In a CAN bus, there are three computers: Computer A, Computer B, and Computer C.
Length in time of the message sent are 2 milliseconds long
As the computer start sending the message; the message are being sent at a message duration rate of 2 milliseconds
250 microseconds later, Computer B starts to send a message; There is a delay of 250 microseconds = 0.25 milliseconds here at Computer B
and 250 microseconds after that, Computer C starts to send a message
Similarly; delay at Computer C = 0.25 milliseconds
Assuming is the retransmit time for Computer A to retransmit its message, Then :
=
= 2 milliseconds + 0.25 milliseconds + 0.25 milliseconds
= 2.5 milliseconds
Thus; the correct option is A) After 2.5 milliseconds
