Answer:
The option that is best described as a way engineers can test and investigate how things should be under certain circumstances is;
Explanation:
Modeling is a tool an engineer can use for the physical representation of a system that will facilitate the definition, testing and analysis, communication, data generation, data verification and data validation of given concepts
Models also aid in setting specifications, supporting designs, and verification of a given system
Therefore, with modeling engineers can investigate the behavior of systems under given environmental conditions.
Answer:
The required wall thickness is
m
Explanation:
Given:
Fluid density

Diameter of tank
m
Length of tank
m
F.S = 4
For A-36 steel yield stress
MPa,
Allowable stress 
MPa
Pressure force is given by,


Pa
Now for a vertical pipe,

Where
required thickness


m
Therefore, the required wall thickness is
m
Answer:
I know it is C)Virtual reality
Explanation:
Look at the clues
story about putting on a headset ( virtual reality head set!)
seeing a digital world (A virtual reality world)
they could walk around in (Fake walking you are basically jogging in place)
explore in order to see what ancient Benin looked like (Looking at a real place only digitally)
as if they were really there ( they think they are actually there)
The only reason I know all of this is because I have done virtual reality multiple times and I LOVED it SUPER fun ( I was doing archery) :) Hope this helps!
Answer: The overhead percentage is 7.7%.
Explanation:
We call overhead, to all those bytes that are delivered to the physical layer, that don't carry real data.
We are told that we have 700 bytes of application data, so all the other bytes are simply overhead, i.e. , 58 bytes composed by the transport layer header, the network layer header, the 14 byte header at the data link layer and the 4 byte trailer at the data link layer.
So, in order to assess the overhead percentage, we divide the overhead bytes between the total quantity of bytes sent to the physical layer, as follows:
OH % = (58 / 758) * 100 = 7.7 %
$2.
Both tickets cost $1.50
$1.50 x 2 = $3
$5 - $3 = $2
