Answer:
No padding
Explanation:
64 bytes is taken as the minimum Ethernet frame, this encompass checksum as well as addresses in the Ethernet frame header and length field. while the maximum Ethernet frame is 1518 bytes, any minimumEthernet frame that is short compare to that will need receiving stations to interpret it as a collision. The question specified that the IP packet to be transmitted by Ethernet as 60 bytes long. The header fields here can occupy 18 bytes, Then total frame size becomes 78 bytes. With the total frame size of 78 bytes(60 bytes+ 18 bytes) we can see it has exceeded the 64-byte minimum. Hence there is no padding used.
Answer: Plotter-- B
Explanation:
A Plotter is sophisticated printer that get commands from a computer and interprets them to draw high quality lines or vector graphics on paper rather than dots using one or several automated pens. This makes them useful in the area of CAD , architecture drawings and engineering designs. The types of plotters we have include Drum Plotters, Flat Bed Plotters and Ink Jet Plotters.

Answer:</h2>
10
<h2>
Explanation:</h2>
Specific gravity (also called relative density) is the ratio of the density of an object (or substance) to the density of a reference substance (mostly water). It has no unit and is given by the following;
Specific gravity = 
Specific gravity is also given by the ratio of the weight of the object in air to the loss of weight of the object in water. i.e
Specific gravity =
--------------(* * *)
In this case;
i. The object is the solid which has a weight of 20gf in air.
ii. The loss of weight of the solid in water is the difference between the weight in air (20gf) and the weight in water (18gf).
Therefore the loss of weight is
20gf - 18gf = 2gf
Now substitute these values from (i) and (ii) into equation (* * *) as follows;
Specific gravity = 
Specific gravity = 10
Therefore the specific gravity of the solid is 10
Scenarios are created and simulated in order to <span>perform a what-if analysis with more than two input cells. These scenarios are very essential to the development of the study of different variables affecting the two input cells who be assessed properly by manipulating and controlling them for the desired outcome.</span>
If there is a bigger supply than demand, it is called a surplus.
