After a Hacker has selects her target, the thing she scan next on the target's network to see if any are open System Ports.
<h3>How do hackers scan ports?</h3>
In port scan, hackers often send a message to all the port, once at a time. The response they tend to receive from each port will help them to known if it's being used and reveals the various weaknesses.
Security techs often conduct port scanning for a lot of network inventory and to show any possible security vulnerabilities.

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
