If it is. DC, direct current reverse the polarity of power leads on the motor.
If it is a 3 phase ac alternating current, reverse any of the two of three leads.
Disconnect power before attempting.
Explanation:
Styrene is a vinyl monomer in which there is a carbon carbon double bond.
The polymerization of the styrene, which is initiated by using a free radical which reacts with the styrene and the compound thus forms react again and again to form polystyrene (PS).
The equation is shown below as:
⇒ ![\begin{matrix}&C_6H_5 \\&|\\ -[-H_2C & -CH-]-_n\end{matrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bmatrix%7D%26C_6H_5%20%5C%5C%26%7C%5C%5C%20-%5B-H_2C%20%26%20-CH-%5D-_n%5Cend%7Bmatrix%7D)
Answer:Decay rate constant,k = 0.00376/hr
Explanation:
IsT Order Rate of reaction is given as
In At/ Ao = -Kt
where [A]t is the final concentration at time t and [A]o is the inital concentration at time 0, and k is the first-order rate constant.
Initial concentration = 80 mg/L
Final concentration = 50 mg/L
Velocity = 40 m/hr
Distance= 5000 m
Time taken = Distance / Time
5000m / 40m/hr = 125 hr
In At/ Ao = -Kt
In 50/80 = -Kt
-0.47 = -kt
- K= -0.47 / 125
k = 0.00376
Decay rate constant,k = 0.00376/hr
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
