Dahasolnce [82]3 years ago
6 0

Answer:

Explanation:

A disk block works by transferring data between the disk and main memory units which are called the blocks, whose size can range drastically from 512 bytes to several thousand.  This data is converted to hardware-level cylinder, surface, and sector number  which makes accessing the data immensely slower than accessing data in the main memory. This time constraint is also the main reason as to why accessing a disk block is so expensive.

total_weight

quantity

weight of one item = total_weight/quantity                      

for i in range(80, 18, -2):

   print(i, end=' ')

Explanation:

The first two questions are just mathematical to get a single quantity given some relationship. So, its basically division

For the python code, I used the python's range function which takes in three arguments. The first one is the starting value, the second one is the terminating value which is the number before the terminating value and the last one specifies the common difference popularly known as step in the language. Since the step is 2, only even numbers are printed out. In the print function, I made use of the end keyword specifying a space (' ') as the end. This ensures that the print is done in the same line with a space seperating them. Without that specification, each result will printed in a newline

castortr0y [4]

Answer:

Option A.

Explanation:

In 3D computer graphics, this process determines which elements should not be visible from the desired point of view, and will prevent them from rendering. Thus, objects that lie behind opaque surfaces such as walls or panels, will not be rendered.

A good rendering algorithm helps to optimize the graphic engine because it will load as few elements as possible. Therefore, in larger worlds, the engine will remain at a stable speed and will be more efficient.
