Answer:

Explanation:
The first thing we will do is convert the units. Miles per hour to meters per second.


Performing the operations

Now, we will use the acceleration formula

Where v = speed and t = time
Substituting the values of 

4.75cm * 5.22cm is 24.795cm²
but let's do this with m² instead:
0.0475m * 0.0522m = 0.0024795
now we can compare it with the 49780 much easier.
devide. that's the <u>roughly</u> 20,000,000fold of the plot, but it's still squared, so let's take the root
so the representative fraction is 1:4,480.
the exact value is in the screens
have a nice day:)
Answer: Protocol model and reference model
Explanation:
There are basically two types of basic network administrator model in the network that is:
Protocol model:
This model is basically represent the 4 layer of the TCP/IP model as it describe the different functionality with the networking data which occur in the each layer of the protocol in the TCP/IP model.
Reference model:
The reference model basically provide the common reference and maintain the consistency in all the different types of the network protocol. The main purpose of this model is that it understand the different functionality of the OSI model and then used in different networking design.
