MAVERICK [17]2 years ago

Answer:

B) Developer is poured down the drain while fixer can be reduced

Explanation:

The effluents produced during photographic processing includes, wash water, bleach, fixer, and developer

The developer is an alkaline solution, with a pH of approximately 10.0, while the pH of the fixer is about 4.3, it is therefore, acidic

The rate of discharge of the developer to the fixer is 2 to 1, and the exhausted developer, fixer and process effluents combined are neutral and can be handle by the the treatment works and the drain pipes

Fixer which remain clear can be reused for more than a day, while the spent basic Developer and the acidic Spent Stop Bath can be combined to form a neutral solution, having a pH of approximately 7, which make them less hazardous to be disposed off down the sink into the drain

Therefore, <em>developer is poured down the drain while fixer can be reused</em>

Assume the availability of a function named oneMore. This function receives an integer and returns one more than its parameter.
jek_recluse [69]

Answer:

oneMore(oneMore(oneMore(oneMore(oneMore(0)))))

Explanation:

  • As a function has been explained which when given an integer results as a next integer. oneMore(given-integer)= next integer
  • As we are restricted to use 0 only and can't use operators like + - * /.
  • We have to obtain a value 5
  • So doing step-by-step:

             (oneMore(0))=1

             (oneMore(oneMore(0)))=2

             (oneMore(oneMore(oneMore(0))))=3

             (oneMore(oneMore(oneMore(oneMore(0)))))=4

             oneMore(oneMore(oneMore(oneMore(oneMore(0)))))=5

If wire rope guard rails are used what must also be done?

A Deceleration device.
A rope, wire rope, or strap with connectors at each end for connecting the 5 point body harness to a lifeline, or anchorage.

Look under OSHA Flashcards on Quizlet and..
OSHA: Fall Protection in Construction, Subpart M and just past that area in the document.

This is from that document on page 13 and 14:  
Fall Restraint Systems:  While fall restraint systems are not mentioned in Subpart M, OSHA recognizes a fall restraint system as a means of prevention. The system, if properly used, tethers a worker in a manner that will not allow a fall of any distance. This system is comprised of a body belt or body harness, an anchorage, connectors, and other necessary equipment. Other components typically include Photo: Skip Pennington OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION 1 4 a lanyard, a lifeline, and other devices. For a restraint system to work, the anchorage must be strong enough to prevent the worker from moving past the point where the system is fully extended, including an appropriate safety factor. *In a November 2, 1995 interpretation letter to Mr. Dennis Gilmore, OSHA suggested that, at a minimum, a fall restraint system must have the capacity to withstand at least 3,000 pounds or twice the maximum expected force that is needed to restrain the person from exposure to the fall hazard. In determining this force, consideration should be given to site-specific factors such as the force generated by a person (including his/her tools, equipment, and materials) walking, slipping, tripping, leaning, or sliding along the work surface.

1) Create a recursive program that prompts the user for a nonnegative integer N and outputs. a) Sum [N] b) BiPower [N] c) TimesF
Georgia [21]

Answer:

//Code is created using java

import java.util.*;

// returns the sum

public int sum(int N)

{

if(N==1)

return (1);

else

return N+sum(N-1);

}

// code to return the Bipower ouput

public int BiPower(int N)

{

if(N==1)

return (2);

else

return 2*BiPower(N-1);

}

// Code to return TimesFive output

public int TimesFive(int N)

{

if(N==1)

return 5;

else

return 5 + timesFive(N-1);

}

public static void main(String args[])

   {

//Prompts the user to enter a nonnegative integer

       int N  = Integer.parseInt.(console.readLine("Enter a nonnegative integer:  "));

//Outputs the sum, Bipower and TimesFive

       System.out.println(sum(n));

       System.out.println(BiPower(n));  

       System.out.println(TimesFive(n));

   }

}
