Answer:
E = 2940 J
Explanation:
It is given that,
Mass, m = 12 kg
Position at which the object is placed, h = 25 m
We need to find the potential energy of the mass. It is given by the formula as follows :
E = mgh
g is acceleration due to gravity
So, the potential energy of the mass is 2940 J.
Answer:
"Macro Instruction"
Explanation:
A macro definition is a rule or pattern that specifies how a certain input sequence should be mapped to a replacement output sequence according to a defined procedure. The mapping process that instantiates a macro use into a specific sequence is known as macro expansion.
It is a series of commands and actions that can be stored and run whenever you need to perform the task. You can record or build a macro and then run it to automatically repeat that series of steps or actions.

Write a statement that assigns freeBooks the appropriate value based on the values of the boolean variable isPremiumCustomer and the int variable nbooksPurchased is described below
Explanation:
Online Book Merchants offers premium customers 1 free book with every purchase of 5 or more books and offers 2 free books with every purchase of 8 or more books. It offers regular customers 1 free book with every purchase of 7 or more books, and offers 2 free books with every purchase of 12 or more books.
A statement that assigns freeBooks the appropriate value based on the values of the boolean variable isPremiumCustomer and the int variable nbooksPurchased. Here's what we have:
if(isPremiumCustomer = true){
if(nbooksPurchased >= 5));
freeBooks = 1;
}else if(nbooksPurchased >= 8){
freeBooks = 2;
}else {
if(nbooksPurchased >= 7);
freeBooks = 1;
}else if(nbooksPurchased >= 12){
freeBooks = 2;
}
We are getting an error of "illegal start of expression".
Two of the hints are "You are using an incorrect number somewhere in your solution" and "We think you might want to consider using: ==".
I do not want the answer, I just want pointed in the right direction.
