Answer:

Gently type on the keyboard.

Set your water bottle on a table that is away from hardware.

Explanation:

The procedures that will keep the computer safe and working properly are:

-Gently type on the keyboard because it will allow it to last longer because if you press the keys too strong they could get stock or it can have problems with the settings and symbols, numbers and letters can start appearing on a different key.

-Set your water bottle on a table that is away from hardware because this will allow you to avoid throwing the water on the computer which will damage it.

The other options will not keep the computer safe and working properly because turning the power off before shutting it down can damage the hard drive, downloading software from the Internet without permission can cause a virus or a malware to infect the computer and washing your hands thoroughly before using the computer won't do anything to maintain it working properly or safer.

Which result would support the particle theory of light?
andriy [413]

This question is related to the emission of electrons when light shines on an metal. (Photoelectric effect)

With the classical theory, it was thought that increasing or decreasing the intensity of light would increase or decrease the kinetic energy of the electron.,

Another expected result was that time gap between when light strikes the metal and when electrons are ejected, would depend on the intensity of such light.

However, the experimental results were not consistent with the particle theory of light. So your answer is A. 

Later on this effect was correctly explained by Einstein based on Planck's findings.

Assure that major, minor, sub1 and sub2 each contain four digit numbersIf less than four digits are entered in major OR minor OR
Zigmanuir [339]

Answer:

import re

#section 1

while True:

   try:

       major=input('Enter Major: ')

       if re.search(r'^\d{1,4}$',major):

           minor=input('Enter minor: ')

       else:

           raise

       try:

           if re.search(r'^\d{1,4}$',minor):

               sub1=input('Enter sub1: ')

           else:

               raise

       

           try:

               if re.search(r'^\d{1,4}$',sub1):

                   sub2=input('Enter sub2: ')

               else:

                   raise

           

               try:

                   if re.search(r'^\d{1,4}$',sub2):

                       break

                   else:

                       raise

               except:

                   print('enter a correct sub 2')

           except:

               print('enter a correct sub1')        

       except:

           print('Enter a correct minor ')            

   except:

        print('enter a correct Major')

#section 2

sub1= f"{int(sub1):04d}"

sub2= f"{int(sub2):04d}"

major= f"{int(major):04d}"

minor= f"{int(minor):04d}"

if major == '0000' and minor == '0000' and sub1=='0000' and sub2=='0000':

   print('INVALID!!! Acount Number')

else:

   print('-----------------------')

   print('Your Account Number is')

   print(major, minor, sub1, sub2)

   print('-----------------------')

Explanation:

The programming language used is python 3

The Regular  Expression Module was imported to allow us perform special operations on string variables.

This is the pattern that was used to check if an input was valid or invalid re.search(r'^\d{1,4}$',string)

what this pattern does is that it ensures that:

  1. (\d) represents digits that is any number from 0-9.
  2. ( ^ ) ensures that it starts with a digit.
  3. ({1,4}) accepts digits with length ranging from 1-4. i.e you can enter at least one digit and at most four digits.
  4. ($) ensures that the input ends with a digit
  5. string is the text that is passed to the pattern

we also made use of fstrings

sub1= f"{int(sub1):04d}"

the above line of code takes 'sub1' in this case, and converts it temporarily to an integer and ensures it has a length of 4 by adding 0's in front of it to convert it to a four digit number.

These are the major though areas, but i'll explain the sections too.

#section 1

In this section the WHILE loop is used in conjunction with the TRY and EXCEPT block and the IF statement to ensure that the correct input is given.

The while loop will keep looping until the correct input is inserted  before it breaks and each input is tested in the try and except block using the if statement and the regular expression pattern I explained, as a result, you cannot input a letter, a blank space, a punctuation or numbers with length greater than 4, it has to be numbers within the range of 1-4.

#section 2

The second section converts each entry to a four digit number and checks with an if statement if the entry is all zeros (0000 0000 0000 0000) and prints invalid.

Otherwise, it prints the account number.

check the attachment to see how the script runs.
