Answer:
False
Explanation:
An abstract class is a class declared abstract — it may or may not include abstract techniques. It is not possible to instantiate abstract classes, but they can be sub-classed.
<u></u>
<u>Abstract method declaration</u>
abstract void moveTo(double X, double Y);
Usually the subclass offers solutions for all of the abstract techniques in its parent class when an abstract class is sub-classed. If not, however, the subclass must be declared abstract as well.
<u>Example</u>
public abstract class GraphicObject {
// declaring fields
// declaring non-abstract methods
abstract void draw();
}
Answer:
Based on the requirements indicated in the question above, the best Local Area Network (LAN) operating system that can be used is
Windows 7 , 8.1 or Windows 10. This is because they all are configured to handle extensive LAN activity and can connect over 200 users.
Explanation:
Generally speaking, Windows 10 packs more improvement over the previous windows.

Answer:
Option D: If it is the month of January, then the temperature is cool.
Explanation:
A conditional statement is the one having an if condition in it that says, if the condition is true proceed to the next statement, else not.
Given statements are:
- If it is the month of January, then it is winter.
This can be written as: if (January)⇒Winter
- If it is winter, then the temperature is cool.
This can be written as: if (winter)⇒ Temperature(cool)
So by combining both the statements, the winter clause will be connected and we get:
if(January)⇒Temperature (cool)
This can be written as:
- If it is the month of January, then the temperature is cool.
So, Option D is the correct answer.
i hope it will help you!
Answer:
Altitude of the town(h1) = 1,196.8 m
Explanation:
Given:
Height of barometer(h) = 65 cm Hg = 0.65
Standard atmospheric pressure = 76 cm Hg = 0.76
Density of mercury(Pm) = 13,600 kg/m³
Density of air (Pa) = 1.25 kg/m³
Find:
Altitude of the town(h1)
Computation:
Pressure due column = Δp mercury column
(Pa)(h1) = (Pm)(h)
(1.25)(h1) = (13,600)(0.76-0.65)
(1.25)(h1) = 1,496
Altitude of the town(h1) = 1,196.8 m
