Answer:
Whenever a new row is inserted, based on the insertion point, the rest of the rows will move down and the reference will be changed accordingly.
Explanation:
Suppose there are 5 columns and ten rows in excel containing the value of student marks from column 2 to 4 in each subject and column 1 contains Student roll number.
There are totally 10 entries in the sheet (number of student = 10) and the column 6 is utilized to calculate total and there is a formula associated to each row to add marks.
When we want to enter another student data below the 5th student, we can insert and the whole row including the formula gets changed thus the reference of formula gets changed. Same is the case for deletion.
Explanation:

R is many - many;
in this case we have that E1 is not what should be used to determine E2 and in this same way, W2 is not what should determine E1. So non of these can be a key on its own.
2.
R is many-one from E1 to E2
in this case there are 2 tuples (f1,f2) and (e1,e2) which have to be the same if they have the same key attribute for E1. All of them are the same so all the pairs are the same.
3.
R is many-one from E2 to E1:
the explanation for this is is almost the same with that of b. we apply the same logic. since for all keys, all pairs and sets are the same.
4.
R is one-one:
E1 is what determines E2 and likewise, E2 is what determines E1. irrespective of the key that is used, key K is going to the same value of n.

Explanation:
Objects suffer inertia before a transition is achieved. Transition is the movement of an object from one state to another. But, this transition does not happen on its own. It is usually triggered by an event or series of events. This means that when the object moves from its prior state to a subsequent state, an event must have occurred to trigger the transition. Objects, therefore, depend on events or an outside force to remove their inertia. They are usually in a state of inertia until an outside stimulus stimulates them with some momentum.
