What does delay(10000) result in? 100 Seconds 10000 Seconds 10 Seconds 10 Minutes

The Correct Answer and Explanation is:

The correct answer is: 10 Seconds

Explanation

In many programming contexts, especially in environments like Arduino or JavaScript-based timing functions, the function delay(10000) is used to pause or delay the execution of a program for a specific amount of time.

The value passed to delay() is typically in milliseconds. A millisecond is one-thousandth of a second. So:

• 1 second = 1000 milliseconds
• 10 seconds = 10 × 1000 = 10000 milliseconds

Therefore, delay(10000) causes a pause of 10 seconds.

Arduino Example:

In the Arduino programming language (which is based on C/C++), delay(ms) is a built-in function that halts the program for the number of milliseconds specified. If you write delay(10000) in an Arduino sketch, the program will stop running for 10 seconds before continuing with the next instructions.

cppCopyEditvoid setup() {
  // Turn on an LED
  digitalWrite(LED_BUILTIN, HIGH);
  // Wait for 10 seconds
  delay(10000);
  // Turn off the LED
  digitalWrite(LED_BUILTIN, LOW);
}

In this example, the LED stays on for exactly 10 seconds due to delay(10000).

JavaScript/Node.js Example:

Although JavaScript doesn’t have a native delay() function like Arduino, libraries or async functions can mimic similar behavior using setTimeout() or await new Promise(resolve => setTimeout(resolve, ms)). Again, the parameter is in milliseconds. So 10000 means 10 seconds.

Why It’s Not the Other Options:

• 100 Seconds would require delay(100000)
• 10000 Seconds would be delay(10000000)
• 10 Minutes would be delay(600000)

Only delay(10000) corresponds to 10 seconds because of the standard millisecond-to-second conversion.

Understanding this is essential when programming time-based behaviors in embedded systems or asynchronous environments.
