What are the cause of eye strain during computer usage?

Natasha2012 [34]

It happens because your eyes follow the same path over and over. And it can get worse the longer you continue the movement. When you work at a computer, your eyes have to focus and refocus all the time. They move back and forth as you read. You may have to look down at papers and then back up to type. Your eyes react to changing images on the screen to create so your brain can process what you’re seeing. All these jobs require a lot of effort from your eye muscles. And to make things worse, unlike a book or piece of paper, the screen adds contrast, flicker, and glare.

You’re more likely to have problems if you already have eye trouble, if you need glasses but don't have them, or if you wear the wrong prescription for computer use.

Computer work gets harder as you age and the lenses in your eyes becomes less flexible. Somewhere around age 40, your ability to focus on near and far objects will start to go away. Your eye doctor will call this condition presbyopia.

A file named loan.html, write an HTML document that looks similar to figure 9-7 in the textbook. Write four functions with these

jok3333 [9.3K]

Answer:

function computePayment(principal, annualRate, periodsPerYear){

var pay;

pay = (principal * annualRate)/(1-(1+annualRate)-periodsPerYear);

return pay;

}

function computeBalance(principal, annualRate, periodsPerYear, numberOfPaymentsPaidToDate){

var balance ;

let num = (principal*(1+annualRate)*periodsPerYear);

let denum = numberOfPaymentsPaidToDate *((1+annualRate) * periodsPerYear-1)*annualRate;

balance = num-denum;

return balance;

}

function doPayment(){

let loanAmount = document.getElementById("principal").value;

let rate = document.getElementById("rate").value;

let duration = document.getElementsById("time").value;

let result = computePayment(loanAmount, rate, duration);

document.getElementsById("periodPay").value = result;

}

function doBalance(){

let loanAmount = document.getElementById("principal").value;

let rate = document.getElementById("rate").value;

let duration = document.getElementById("time").value;

let currentPaid = document.getElementById("paidMonths").value;

let result = computeBalance(loanAmount, rate, duration, currentPaid);

document.getElementById("displayBalance").value = result;

}

Explanation:

The javascript source code defines four functions. The 'doPayment' and 'doBalance' functions are initiated with the onclick properties of the HTML file buttons of the loan calculator. The doPayment function gets the user input from the HTML file and assigns them to variable which are used as the parameters of the computePayment function called.

The doBalance function also retrieve user input from the HTML file and calls the computeBalance function to calculate and return the balance of the loan to be paid.

A new laptop was delivered to your home and left on the porch while you were at work. It is very cold outside, and you don't kno

kifflom [539]

Answer:

Let the computer warm up to room temperature before turning it on.

Explanation:

The laptop has been shipped to the user's home when he were at work and found on the deck. Outside it is really cool and he don't remember how long it has been there. Then, the user open his laptop and want to know whether it is functioning properly. Instead, let the machine warm up while switching it on to room temperature.

When a computer is still in a cold climate, they have to let it heat up to room temperature apx. 6-24 hours before switching it on. Otherwise, its heat the elements generate could cause water moisture within the laptop. That water could then harm elements of the system.
