Open system because there is mass (water) flowing through the system of interest (radiator)
Answer:
As there was no attached picture, I will explain how to take the measurement of liquids in any buret which you can then apply to the specific question
Explanation:
A buret is a laboratory apparatus used to precisely measure the volume of liquids (usually alkalise or bases) used in a titration experiment. The standard buret has a capacity of 50 ml and graduated in 0.1ml though burets with smaller capacities exist.
From the question, your buret is filled to the top (0.00ml) with liquid. It is very important when taking buret readings to place the buret below your eye level so that the bottom meniscus (lower part of the liquid) can be read.
To take the buret reading, note your initial buret reading (in this case 0.00ml) then titrate the liquid base in the buret against the acid by opening the tap located at the bottom of the buret.
When the titration or reaction is complete, note the final reading against the calibration of buret. You can do this by observing the lower meniscus of the liquid remaining in the buret. (Remember to keep the buret at eye level to avoid parallax error),
The difference between your final buret reading and the initial buret reading gives you the precise volume of liquid used in the reaction.
Answer:
d. The company uses role-based access control and her user account hasn't been migrated into the correct group(s) yet
Explanation:
Since Deidre is accessing her e-mail there appears to be nothing wrong with her account or password. Since her role is new, most likely the problem is associated with her new role.
Answer:
#include<iostream>
Using namespace std;
int main()
{
int n, qty;
double price, amount;
cout<<"Number of items ";
cin>>n;
cout<<"ITEM<<"\t"<<"QUANTITY"<<"\t"<<"PRICE"<<"\t"<<"ITEM TOTAL";
for(int i= 1; I<= n; i++)
{
cin>>qty;
cin>>price;
amount = qty * price;
cout<<i<<"\t "<<qty<<"\t"<<price<<"\t"<<amount;
}
}
Explanation
The above program is written in C++ programming language
5 variables are declared and used in the program
n is declared as an integer to represent the total number of items
qty is declared as integer to represent the total quantity of each item
price is declared as double to represent the amount of each individual item
amount is declared as double to represent the total amount of an item; it is gotten by qty * price
i is declared as integer to iterated between each items
The amount of each item is calculated within the iteration and also printed immediately
