Explain why a single 500 kg block of granite weathers much more slowly than 100 chunks of granite weighing 5 kg each.

Bad White [126]

Weathering occurs on the surface of rocks, and lots of small rocks have a much greater surface area than one big rock.

Assume that two classes 'Temperature' and 'Sensor' have been defined. 'Temperature' has a constructor that accepts a double para

Black_prince [1.1K]

Answer:

The answer for the following question is given as:

public static Temperature create(Sensor ob)

{

return new Temperature(ob.getReading());

}

Explanation:

In this we have create a static method of Temperature class which accept a 'Sensor' object and return the new 'Temperature' object that calls the 'getReading()' function This function returns the sensor's current reading.

6.23 LAB: Convert to binary - functions Instructor note: This is a lab from a previous chapter that now requires the use of a fu

Kitty [74]

Answer:

The program in Python is as follows:

import math

def integer_to_reverse_binary(integer_value):

remainder = ""

while integer_value>=1:

remainder+=str(integer_value % 2)

integer_value=math.floor(integer_value/2)

reverse_string(remainder)

def reverse_string(input_string):

binaryOutput=""

for i in range(len(input_string)-1,-1,-1):

binaryOutput = binaryOutput + input_string[i]

print(binaryOutput)

integer_value = int(input("Enter a Number : "))

integer_to_reverse_binary(integer_value)

Explanation:

This imports the math module

import math

This defines the integer_to_reverse_binary function

def integer_to_reverse_binary(integer_value):

This initializes the remainder to an empty string

remainder = ""

This loop is repeated while the integer input is greater than or equal to 1

while integer_value>=1:

This calculates the remainder after the integer value is divided by 2

remainder+=str(integer_value % 2)

This gets the floor division of the integer input by 2

integer_value=math.floor(integer_value/2)

This passes the remainder to the reverse_string function

reverse_string(remainder)

The reverse_string function begins here

def reverse_string(input_string):

This initializes the binaryOutput to an empty string

binaryOutput=""

This iterates through the input string i.e. the string of the remainders

for i in range(len(input_string)-1,-1,-1):

This reverses the input string

binaryOutput = binaryOutput + input_string[i]

This prints the binary output

print(binaryOutput)

<u>The main begins here</u>

This gets input for integer_value

integer_value = int(input("Enter a Number : "))

This passes the integer value to the integer_to_reverse_binary function

integer_to_reverse_binary(integer_value)

Using Module operator, write a java program to print odd number between 0 and 1000

jolli1 [7]

Answer:

class OddNumber

{

public static void main(String args[])

{

int n = 1000; //Store 1000 in Variable n typed integer

System.out.print("Odd Numbers from 1 to 1000 are:"); // Print headline of output window

for (int i = 1; i <= n; i++) //For loop to go through each number till end

{

if (i % 2 != 0) //check if number is even or odd.Not divisible by 2 without reminder means it is odd number

{

System.out.print(i + " "); //print odd numbers

}

In this assignment we are going to practice reading from a file and writing the results of your program into a file. We are goin

zhenek [66]

Answer:

In Python:

import os.path

from os import path

fname = input("Filename: ")

if path.exists(fname):

with open(fname) as file_in:

lines = []

for line in file_in:

lines.append(line.rstrip('\n'))

f = open("stat.txt","r+")

f.truncate(0)

f = open("stat.txt", "a")

f.write("Names\tTotal\tSubjects\tAverage\n")

for i in range(len(lines)):

rowsum = 0; count = 0

nm = lines[i].split()

for j in nm:

if (j.isdecimal()):

count+=1

rowsum+=int(j)

average = rowsum/count

f.write(nm[0]+"\t %3d\t %2d\t\t %.2f\n" % (rowsum, count, average))

f.close()

else:

print("File does not exist")
