Consider an exchange of HDLC frames using go-back-N with a 3 bit sequence number for N(S) and a 3 bit sequence number for N(R). Complete the following figure by entering the correct numbers for N(S) and N(R). How do i do this?
A – N(S) = 7, N(R) = 6

B – N(S) = __, N(R) = __

C – N(S) = __, N(R) = __

D – N(S) = __, N(R) = __

E – N(S) = __, N(R) = __

F – N(S) = __, N(R) = __

G – N(S) = __, N(R) = __

H – N(S) = __, N(R) = __

If the absolute value is the distance from zero then how can anything be a negative? Example: I-2I=2 I2I=2. Can someone explain why "absolute value of x = -x if x is negative"? This is the definition in the book.

A block starts at rest and slides down a fric-
tionless track.
The acceleration of gravity is 9.81 m/s2 .
It leaves the track horizontally, striking the
ground.

a) At what height h1 above the ground is the
block released? Answer in units of m.


Givens: h2(second height)=2.6m
Mass m of block = 481g
After leaving the track the block lands 5.2m away from the
point it leaves.



What is the speed of the block when it
leaves the track? Answer in units of m/s

What is the speed of the block when it hits
the ground? Answer in units of m/s.

Insulin, a protein molecule produced in the beta cells of the Islets of Langerhans of the pancreas, is secreted directly into the bloodstream. Describe the pathway that an insulin molecule takes through the endomembrane system of the cell from transcription to secretion.

This answer needs to include information on transcription, modification of the original RNA transcript to make mRNA, and attachment of ribosomes to the ER to produce the insulin into the lumen of the ER.
