T/F: If cartesian join is used to link table A which contains five rows to table B which contains eight rows, there will be 13 rows in the result.
Answers
The statement is False. If a Cartesian join is used to link table A with five rows to table B with eight rows, there will be 40 rows in the result (5 rows from table A multiplied by 8 rows from table B).
When performing a cartesian join, every row from table A is combined with every row from table B.
Therefore, the total number of rows in the result set is equal to the product of the number of rows in each table. In this case, there are 5 rows in table A and 8 rows in table B, so the cartesian join will result in 5 x 8 = 40 rows.
The statement is False. If a Cartesian join is used to link table A with five rows to table B with eight rows, there will be 40 rows in the result (5 rows from table A multiplied by 8 rows from table B).
The Cartesian join combines every row from table A with every row from table B, resulting in the total number of rows being the product of the row counts of both tables.
However, it's important to note that not all of these rows may be relevant or meaningful to the query being executed. It's always important to carefully consider the use of a cartesian join and whether there are more efficient ways to achieve the desired result.

If the postorder traversal of an expression tree is 8, 2, +, 5, /, what is the preorder traversal?
Answers
Preorder traversing is the process all nodes of a tree by processing the root, then recursively processing all subtrees. Also known as prefix traversal.
What is Tree traversal?In computer science, the practice of visiting (e.g., obtaining, updating, or deleting) each node in a tree data structure precisely once is known as tree traversal, also known as tree search and traversing the tree.By the sequence in which the nodes are traversed, such traversals are categorized. The ensuing techniques are explained in terms of a binary tree, although they may also be applied to other types of trees.Iterating over each node in some way is necessary to traverse a tree. Since there are several possible next nodes from a particular node (it is not a linear data structure), certain nodes must be deferred—stored in some form for later visiting—in the case of sequential processing (not parallel).To learn more about complete binary tree, refer to:

If the air conditioner above were run for 180 hours per month, how much energy is used? If it costs $0.12/kWh, how much will it cost to run the air conditioner?
Answers
Answer:
Explanation:
Given that:
Power, P = 1800W
Voltage, V = 210 V
Current, I flowing through the air conditioner;
Recall :
P = IV
1800 = I * 210
I = 1800 / 210
I = 8.5714
Current flowing through the air conditioner = 8.57 ampere
If air-conditioner runs for 180 hours per month,
Energy used = Power * time
Energy used = 1800 * 180
Energy used = 324000Wh
1Kw = 1000 W
324000 / 1000 = 324 Kwh
If charge = $0.12 per kwh

calculate the overall speedup of a system that spends 40% of its time in calculations with a processor upgrade that provides for 100% greater throughput
Answers
The overall speedup of the system can be calculated as 1 / 0.8 = 1.25 or 125%. This means that the system with the processor upgrade is 25% faster than the old system.
To calculate the overall speedup of a system with a processor upgrade, we first need to understand what speedup means. Speedup refers to the ratio of the time it takes for a task to complete on the old system to the time it takes for the same task to complete on the new system.
In this case, the system spends 40% of its time in calculations, which means that the remaining 60% of the time is spent on other tasks (such as input/output operations or waiting for data). Therefore, the processor upgrade will only affect the 40% of the time spent on calculations.
With a processor upgrade that provides for 100% greater throughput, we can assume that the time it takes for calculations to complete will be halved (since 100% greater throughput means twice the processing power).
So, the new time it takes for calculations to complete will be 40% * 0.5 = 20% of the total time. The remaining 60% of the time will remain unchanged.
Overall, the new time it takes for the system to complete a task will be 20% + 60% = 80% of the old time.
