Answer:
FALSE
Explanation:
Because C1 and C2 implement the same interface, they both implement whichIsIt. The variable c is known as a polymorphic variable, meaning that it can change from being an C1 to a C2. So, the message c.whichIsIt( ); may invoke C1's whichIsIt or C2's whichIsIt. This can only be known at runtime.
Answer: Data from multiple workbooks can be combined in a single step.
Explanation:
The Subtotal command allows the creation of groups automatically and common functions such as COUNT, SUM, and AVERAGE are used in the summarizing of data.
An advantage of using the Subtotal dialog box is that data from multiple workbooks can be combined in a single step. Therefore, the correct option is B.
Answer:
Follows are the matching to this question:
Explanation:
Column A Column B
1 c
2 d
3 b
4 a
Description of the matching:
- In 1(Acid) the correct choice is (c) because the acid (HCl) dissociates to both the H+ ion and the Cl- ion as a solution.
- In 2(Alkaline ) the correct choice is (d) because alkaline NaOH is a solution that differentiates between the ions ( OH-) and Na+.
- In 3(pH ) the correct choice is (b) because for an A compound of less than 7 is an acid and an alkaline pH compound of more than 7. For neutral compounds, a pH of 7 is applicable.
- In 4(Ion) the correct choice is (a) because Na+ ion is loaded positive, and Cl-ion is loaded negatively.
Answer:
False
Explanation:
The statement being made here is a False statement. An internet layer is not necessarily a quantity of data but instead, it is a group of various different codes, programs, and protocols that allow from the data to travel safely from one endpoint to the other. This is what allows one user from one side of the world to send information to someone else who can receive it from the other side of the world through the internet.
