<h3><u>Answer;</u></h3>
A. P = E2/R
<h3><u>Explanation</u>;</h3>
Based on the context of electricity the formula for power is given by
P = E2/R; where
P is power in Watts;
I is current in Amps;
R is resistance in Ohms; and
E is voltage in Volts.
The formula may also be given as P = V2/R
<u>Answer:</u>
<em>If we analyze the given piece of code, C1, C2, C3 and C4 are 4 classes. </em>
- C1 is the base class and does not derive from any other class.
- C2 is a class which inherits C1.
- C3 is a class which inherits C2 and indirectly inherits from C1.
- C4 is a class which inherits C1 directly. If analyses the instance creation statement,
<em>c1 instance of C1 is valid because the object is created for class C1.</em>
<em>c1 c2 = new C2() is valid once again the object is created for Class C2</em>
<em>c1 c3 = new C3() is invalid because the class C3 directly inherits from C2 and not from C1</em>
<em>c1 c4 = new C4() is valid</em>
Answer:
Algorithm:
1. Declare variables "cost","state_tax" and "federal_tax".
2.Initialize these variables.
3.Create a variable "cust_money".
3.1 Ask user to give money.
3.2 Assign this to "cust_money".
4. Calculate total_tax=state_tax+federal_tax
4.1 Calculate total_to_be_paid=cost(1+total_tax)
5. Calculate change_to_give= cust_money-total_to_be_paid
6.Print the change_to_give
7. End the program.
Explanation:
Declare variables and initialize "cost" with initial cost of item, "state_tax" with state tax and "federal_tax" with federal tax on the item. Ask user to give money and assign it to "cust_money". calculate the total tax=state+federal tax. Then calculate the total to be paid for item as cost*(1+total tax). Subtract the total paid from customer money and print the change to give user.
