Answer:
The steady-state temperature difference is 2.42 K
Explanation:
Rate of heat transfer = kA∆T/t
Rate of heat transfer = 6 W
k is the heat transfer coefficient = 152 W/m.K
A is the area of the square silicon = width^2 = (7/1000)^2 = 4.9×10^-5 m^2
t is the thickness of the silicon = 3 mm = 3/1000 = 0.003 m
6 = 152×4.9×10^-5×∆T/0.003
∆T = 6×0.003/152×4.9×10^-5 = 2.42 K
Answer:
hazardous chemicals leaving the workplace is labeled, tagged or marked with the following information: product identifier; signal word; hazard statement
Explanation:
this is so you know what chemicals are in it
Answer:
#include <iostream>
using namespace std;
int main()
{
int inputNumber ;
cout << "Enter an interstate highway number:";
cin >> inputNumber ;
if(inputNumber<=0 || inputNumber >= 1000)
cout << inputNumber << " is not a valid interstate highway number" << endl ;
else{
if(inputNumber > 99){
cout << "I-"<<inputNumber<< " is auxiliary, ";
int temp = inputNumber % 100 ;
cout <<"serving I-"<<temp<<", ";
if(temp%2==0){
cout << "going east/west." << endl;
}
else{
cout << "going north/south." << endl;
}
}
else{
cout << "I-"<<inputNumber<< " is primary, ";
if(inputNumber%2==0){
cout << "going east/west." << endl;
}
else{
cout << "going north/south." << endl;
}
}
}
return 0;
}
Explanation:
- Check if input number is greater than 99, then display that the input number is auxiliary.
-
Check if remainder of input number/2 is equal to 0, then display that going east/west.
Answer:
In the line marked *, the strategy that was used was renaming a fraction
The expression de-c fills in the orange box.
Explanation:
just did those questions 2020egen
Answer:
forward voltage triggering
temperature triggering
dv/dt triggering
light triggering
gate triggering
Then turning off;
Turn off is accomplished by a "negative voltage" pulse between the gate and cathode terminals
