Answer:
true
Explanation:
The command:
find -empty -type f -exec rm { } \;
carries out the following steps.
1) Finds all the empty files in the current directory and its subdirectories.
2) For each of the identified files, it executes the command specified as the parameter to exec option,namely, rm <filename>.
So effectively it removes all empty files in the directory tree starting at the current directory.
Answer:
the correct option is (A)
Explanation:
According to the given scenario, the system on a chip is a chip that is different from the microcontrollers in terms of complexity and rise on the chip resources
The system on a chip is a circuit i.e. integrated most the computer things
hence, the correct option is (A).
Therefore the rest of the options are wrong
Answer:
The program to this question can be given as:
Program:
#include <stdio.h> //include header files
#include<math.h>
int main() //main method
{
double treeHeight = 0.0; //declare variables
and assign value
double shadowLength = 0.0;
double angleElevation = 0.11693706;
// (0.11693706 radians = 6.7 degrees) convert number into angle.
shadowLength = 17.5;
treeHeight = shadowLength * tan(angleElevation); //convert number into angle
printf("Tree height: %lf\n", treeHeight); //print value.
return 0;
}
Output:
Tree height: 2.055778
Explanation:
In the above C language program firstly we include the headers. In this header file, we include a (math.h) header file this file helps to use the math function. Then we declare the main method in the main method we declare the variable that is given in the question that are treeHeight, shadowLength , angleElevation. All the variable datatype is double because it stores the floating-point value. Then we apply the formula that is treeHeight = shadowLength * tan(angleElevation). In this formula, the treeHeight variable holds the value. Then we print the variable value for print the double value we use the lf(that is long float).
Answer:
latency
Explanation:
We could have latency if we want to record with a computer, and then we try to hear that record with the headphone.
This is an audio card's characteristic, this is a time between the input, in this case, Sarah recording, and the output Sarah's headphone.
The computer needs time to process the signal, and for that there is latency, but this depends on more of the operative system and the CPU in your computer than the audio card.
