You can raise an object to a height of 2 meters by pulling down a distance of 8 meters on a pulley with a force of 40 N. How heavy an object can you lift with his effort?

Answers

Answer:

160 N

Explanation:

Since, work done by effort = work done by load,

Fd = F'd' where F = effort force = 40 N, d = distance moved by effort = 8 m, F = load and d' = distance moved by load = 2 m.

So, Fd = F'd'

40 N × 8 m = F' × 2 m

320 Nm = 2F m

So, F = 320 Nm/2m

= 160 N

So, the object that can be lifted is an object of 160 N

What is an Array?

An array is a type of data structure used in computer science that holds a set of elements that are all uniquely recognized by at least one array index or key. Each element of an array is recorded such that a mathematical formula may be used to determine its location from its index tuple.

Indexed arrays, multidimensional arrays, and associative arrays are the three types of arrays.

A procedure called indexing selects a subset of values from an array. A value's position inside an array is indicated by its index. The location of the value in an array differs from the value itself.

A bubble starts by comparing the first item in the list to all the remaining items, and swaps where the first item is greater than a later item. Thus, option A is correct.

What happens in a binary sort?

Such a binary sort, in which we keep comparing the pairs of items, swapping them if they are not in order, until the smallest item bubble to the top of the list, therefore creating a sorted list which is known as bubble sort.

A Binary search tree (BST) is a type of data structure used in computer science that consists of nodes arranged in a hierarchical structure. Each node in a BST contains a value, and the left child node contains a value that is smaller than its parent, while the right child node contains a value that is larger than its parent.

This makes BSTs ordered, as the elements are arranged in a specific order. They are also sometimes called sorted binary trees, as the values are sorted in a specific order. BSTs are commonly used in computer algorithms, as they allow for efficient searching, insertion, and deletion of elements.

Thus, option A is correct.

An eReader has a 956-pixel x 1290-pixel grayscale display with each pixel able to display 32 shades of gray. What is the KiB size of the display memory for the device

Answers

Answer:

752.71 kilobytes

Explanation:

Given ;

956-pixel x 1290-pixel

Shades of gray, = 32

Bit depth (n) = 2^n

32 = 2^5

Bit depth, n = 5 bits / pixel

The size of display memory :

Pixel dimension * n

(956 Pixel * 1290 pixel) * 5 bits /pixel

= 6166200 pixel * bits / pixel

= 6166200 bits

Converting bits to kilobytes :

1 bit = 1/8 bytes

1 byte = 1/1024 kilobytes

Hence,

1 bit = 1/(8 * 1024) kilobytes

1 bit = 1/8192 kilobytes

6166200 bits = (1/8192 * 6166200) kilobytes

= 752.7099609375 kilobytes

= 752.71 kilobytes

In the first iteration, the variable numB is 2, since 2 is less than 15, the program will run the command

numB = numB+5 and it will print 7

The second iteration is still valid because numB is now 7 and is less than 15, so the program will run the command

numB = numB+5 and it will print 12

The third iteration is still valid because numB is now 12 and is less than 15, so the program will run the command

numB = numB+5 and it will print 17

The fourth iteration is not valid because numB is now 17 and is greater than 15, so the program will not run the command

A shop will give discount of 10% if the cost of purchased quantity is more than 1000. Ask user for quantity suppose, one unit will cost 100. Judge and print total cost for user.

Answers

Answer:

The program in Python is as follows:

qty = int(input("Quantity: "))

price = 100 * qty

if qty >1000:

    price = (100 - 0.10 * 100) * qty

print("Cost: "+str(price))

Explanation:

This prompts the user for the quantity

qty = int(input("Quantity: "))

This calculates the price or cost, without discount

price = 100 * qty

This checks if the quantity is greater than 1000

if qty >1000:

If yes, this calculates the price or cost, after discount

    price = (100 - 0.10 * 100) * qty

This prints the calculated cost

print("Cost: "+str(price))
