Answers

Answer 1

Answer:

Option B

Explanation:

The operating system is the type of software that is responsible for managing the processor time and also the memory allocation in the system. The operating system mainldeals with the processor time by scheduling the processor work done in the system.

The OS mainly controls the system and then schedule the execution of various types of function by the central processing unit (CPU). It also controls the memory allocation in the system.

Answer 2

The part of the computer responsible for managing memory allocation for all applications is the operating system. The correct option is B.

What is an operating system?

The operating system is the kind of software in charge of controlling the system's memory allocation and CPU usage. By scheduling the system's processor work, the operating system primarily manages processor time.

The operating system (OS) primarily manages the system and schedules the central processor unit's performance of many types of functions. Additionally, it manages the system's memory allocation.

The CPU is the brain of the computer. It manages all the functions of the computer. It is a small rectangle chip-like structure present inside the box with other parts.

Thus, the part of the computer that is responsible for managing memory is the operating system. The correct option is B.

Building a String Library

Sometimes when programming you need to introduce a new data type and develop a library of functions for manipulating instances of that data type. Often this is done as methods on a new class but not always.

In this assignment, you'll be defining a collection of functions on strings, most of which already exist as methods on the str class. However, you should pretend that they don't already exist and define them as functions. Of course, you can't just use the existing methods. This will give you a bunch of practice on manipulating strings and also on defining functions.

In this assignment, you'll be defining a collection of functions on strings. You should define each of these as a new function with a function header as below. The description of each is in the comment supplied. Recall that strings are immutable, so you will have to return a new copy of the string for those that call for you to return a string. If you are returning the same string as the input, just return it; there is no need to make a new copy, and it wouldn't anyway.

The only string functions/methods to use:

ord, chr
indexing and slicing
append (i.e., ``+'')
len, in, not in
equality comparison (== or !=))
Looping over strings (while or for loops) and selection (if statements) are allowed. BUT You cannot convert the strings to other types such as lists.

Define each of the following functions, with semantics as indicated by the comment. In each of the following ch is a single character, str, str1, str2 are strings, and i is a non-negative integer. You do not have to validate the inputs, except as indicated; you can assume these types.

At least one question asks you to return two values. That really means returning a tuple (pair) of values. You do that as follows:

return value1, value2
This actually returns the pair (value1, value2). The caller can then assign the members of the pair to two variables:

x, y = pairReturningFunction() # assumes function returns a pair
z, w = (value1, value2) # assigning a tuple to 2 variables
If you like, you can use earlier functions in later ones, or define helper functions, though it shouldn't really be necessary. Note that some of these are trivial to write, while others are a bit harder. I have done the first one for you.

def myAppend( str, ch ):
# Return a new string that is like str but with
# character ch added at the end
return str + ch

def myCount( str, ch ):
# Return the number of times character ch appears
# in str.

def myExtend( str1, str2 ):
# Return a new string that contains the elements of
# str1 followed by the elements of str2, in the same
# order they appear in str2.

def myMin( str ):
# Return the character in str with the lowest ASCII code.
# If str is empty, print "Empty string: no min value"
# and return None.

def myInsert( str, i, ch ):
# Return a new string like str except that ch has been
# inserted at the ith position. I.e., the string is now
# one character longer than before. Print "Invalid index" if
# i is greater than the length of str and return None.

def myPop( str, i ):
# Return two results:
# 1. a new string that is like str but with the ith
# element removed;
# 2. the value that was removed.
# Print "Invalid index" if i is greater than or
# equal to len(str), and return str unchanged and None

def myFind( str, ch ):
# Return the index of the first (leftmost) occurrence of
# ch in str, if any. Return -1 if ch does not occur in str.

def myRFind( str, ch ):
# Return the index of the last (rightmost) occurrence of
# ch in str, if any. Return -1 if ch does not occur in str.

def myRemove( str, ch ):
# Return a new string with the first occurrence of ch
# removed. If there is none, return str.

def myRemoveAll( str, ch ):
# Return a new string with all occurrences of ch.
# removed. If there are none, return str.

def myReverse( str ):
# Return a new string like str but with the characters
# in the reverse order.

Answers

Answer:

125.28₁₀ in hexadecimal = 7D.47AE147AE1₁₆

Step-by-Step Explanation:

To convert decimal number 125.28, we convert its integer and fraction part individually and then add them to get the equivalent hexadecimal number, as below:

To convert integer 125 to hexadecimal, follow these steps:

Divide 125 by 16 keeping notice of the quotient and the remainder. Continue dividing the quotient by 2 until you get a quotient of zero.

Then just write out the remainders in the reverse order to get the equivalent hexadecimal number.

125 / 16 = 7 with remainder 13 (D)

7 / 16 = 0 with remainder 7

Here is the answer to 125 decimal to hexadecimal number:

7D

For converting decimal fraction 0.28 to hexadecimal number, follow these steps:

Multiply 0.28 by 16 keeping notice of the resulting integer and fractional part. Continue multiplying by 16 until you get a resulting fractional part equal to zero (we calcuclate upto ten digits).

Then just write out the integer parts from the results of each multiplication to get equivalent hexadecimal number.

0.28 × 16 = 4 + 0.48

0.48 × 16 = 7 + 0.68000000000001

0.68000000000001 × 16 = 10 (A) + 0.88000000000011

0.88000000000011 × 16 = 14 (E) + 0.080000000001746

0.080000000001746 × 16 = 1 + 0.28000000002794

0.28000000002794 × 16 = 4 + 0.48000000044703

0.48000000044703 × 16 = 7 + 0.68000000715256

0.68000000715256 × 16 = 10 (A) + 0.88000011444092

0.88000011444092 × 16 = 14 (E) + 0.080001831054688

0.080001831054688 × 16 = 1 + 0.280029296875

Here is the answer to 0.28 decimal to hexadecimal number:

0.47AE147AE1

Therefore, decimal number 125.28 converted to hexadecimal is equal:

7D.47AE147AE1

Answers

Primary sources would be best

The primary source would provide the best way to find valid information about climate change.

What is Climate change?

Climate change may be defined as the change in the average conditions such as temperature and rainfall in a region over a long period of time. In more simple words, climate change refers to the long-term shifts in temperatures and weather patterns.

The burning of fossil fuels like coal, oil, and gas for electricity, heat, and transportation is the primary source of human-generated emissions. A second major source is a deforestation, which releases sequestered (or stored) carbon into the air.

Both of these sources are significantly responsible for the causation of climate change in the specific region over a long period of time.

What’s the relationship among speed frequency and the number of poles in a three phase induction motor

Answers

Answer:

The number of poles in the windings defines the motor's ideal speed. A motor with a higher number of poles will have a slower rated speed but a higher rated torque.

Explanation:

The relationship among speed, frequency, and the number of poles in a three-phase induction motor is governed by what is known as the synchronous speed equation.

The synchronous speed of an induction motor is the speed at which the rotating magnetic field generated by the stator windings of the motor rotates.

The synchronous speed (Ns) of a three-phase induction motor is given by the following equation:

Ns = (120 × f) / P

where:

Ns is the synchronous speed in revolutions per minute (RPM).

f is the supply frequency in hertz (Hz).

P is the number of poles.

From the equation, it can be observed that the synchronous speed is directly proportional to the frequency and inversely proportional to the number of poles.

This means that if the frequency increases, the synchronous speed also increases, assuming the number of poles remains constant.

Conversely, if the frequency decreases, the synchronous speed decreases.

The actual speed of an induction motor is known as the rotor speed or slip speed, which is always slightly lower than the synchronous speed. The difference between the synchronous speed and the actual speed is referred to as slip and is necessary for the motor to induce a voltage in the rotor and generate torque.

It's important to note that the synchronous speed equation assumes an ideal motor with no load. In practice, the actual speed of the motor depends on various factors, including the load torque, rotor resistance, and motor design.

A data analyst is working with a data frame named retail. It has separate columns for dollars (price_dollars) and cents (price_cents). The analyst wants to combine the two columns into a single column named price, with the dollars and cents separated by a decimal point. For example, if the value in the price_dollars column is 10, and the value in the price_cents column is 50, the value in the price column will be 10.50. What code chunk lets the analyst create the price column

Answers

The code chunk that lets the analyst create the price column is;

unite(retail, “price”, price_dollars, price_cents, sep=”.”)

The code chunk unite(retail, “price”, price_dollars, price_cents, sep=”.”) is the one that will allow the analyst to create the price column.

The reason for that answer is that;

The unite() function would allow the analyst  to make the dollars and cents data to be combined into a single column.Meanwhile, in the parentheses of the given function, the analyst will write the name of the data frame.Next step for the analyst is to write the name of the new column in quotation marks.Next step is the names of the two columns they want to combine.Lastly, the argument sep=”.” will now place a decimal point between the dollars and cents data given in the price column.
