Answer:
C. means that the natural variation of the process must be small enough to produce products that meet the standard.
Explanation:
Process capability is the statistical measure of the inherent process variability of a given characteristics. we ca use a process capability study to assess the capability of a process to meet specification.
C. means that the natural variation of the process must be small enough to produce products that meet the standard.
Refractive index is the ration of sin i to sin r where i is the incident angle and r is the refraction angle.
Therefore, refractive index = sin 79.5 / sin 39.6
= 1.542
The refractive index may be given by the ratio of refractive index of medium 2 to refractive index of medium 1.
Therefore, 1.542 = n/1.0003
n = 1.5425
≈ 1.54
Medium 2 is sodium chloride, refractive index of 1.54
Answer:
#include <iostream>
#include <vector>
using namespace std;
int main() {
const int NUM_GUESSES = 3;
vector<int> userGuesses(NUM_GUESSES);
int i = 0;
int uGuess = 0;
for(i = 0; i <= userGuesses.size() - 1; i++){
cin >> uGuess;
userGuesses.at(i) = uGuess;
}
cout << endl;
return 0;
}
Explanation:
First inbuilt library were imported. Then inside the main( ) function, 3 was assigned to NUM_GUESSES meaning the user is to guess 3 numbers. Next, a vector was defined with a size of NUM_GUESSES.
Then a for-loop is use to receive user guess via cin and each guess is assigned to the vector.
The distance travelled by the object in the time interval of 3 second is 44.15m
The airresistance would try to decrease the acceleration and thus would decrease the distance the ibject has fallen in 3 seconds.
Explanation:
The object is falling vertically down. Hence the acceleration would be replaced by the acceleration due to gravity "g".
We know that distance "s"= ut +1/2*g*t²
where u- initial velocity of the object
g- acceleration due to gravity= 9.81m/s²
t- time period
Since the object is falling from initial rest position hence u=0
thus the equation reduces to 1/2gt²
S=1/2*(9.81)(3)²
Thus the distance =44.145 m(approximately 44.15 m)
If a small amount of air resistance is present in between it would obstruct the falling of the object. hence, in turn, would oppose "g".
This opposition to "g" would decrease the acceleration and thus body would travel less distance in the same time frame i.e. 3 sec
