Answer:
David can apply filter to the data in order to show only records that meet the criteria.
Explanation:
- Filter is a very helpful option that displays the records that you want to view, hiding rest of the unwanted records.
- Sometimes you want to extract and view only the records that match a specific criteria instead of viewing all the records.
- For example in the CUSTOMERS table which contains names, addresses, countries of customers. There are several customers from different countries but you only want to view the customers from Spain. So you can use filter feature to view all the customers from country Spain.
- In MS Access you can apply filters using Sort & Filter group in the Home tab by selecting the desired column. In SQL, WHERE clause can be used along with SELECT to for filtering and extracting certain records. SELECT will select the records from the table and WHERE clause will specify the criteria to select the certain records.
Answer:
The C's malloc and free functions and the C++'s new and delete operators execute similar operations but in different ways and return results.
Explanation:
- The new and delete operators return a fully typed pointer while the malloc and free functions return a void pointer.
-The new and delete operators do not return a null value on failure but the malloc/free functions do.
- The new/delete operator memory is allocated from free store while the malloc/free functions allocate from heap.
- The new/delete operators can add a new memory allocator to help with low memory but the malloc/free functions can't.
- The compiler calculates the size of the new/delete operator array while the malloc/free functions manually calculate array size as specified.
One approach to solving this is to first calculate the current the will flow through all three resistors:
The total resistance is R1+R2+R3 = 5280
I = V/R = 30/5280 ≈ 5,682 mA
Then the drop across R2 = I*R2 = 5,7mA * 1000 ≈ 5.682 V.
So this is based on the fact that V=I*R and there is one current running in the entire chain, ie., it is the same through each resistor.
