Answer:
the answer is D
Explanation:
Since the velocity of the object is the derivative of the position graph, the area under the line in the velocity vs. time graph is the displacement of the object.
Answer:
a magnet that retains its magnetic properties in the absence of an inducing field or current
Answer:
1 A, 3 B, and 7 A are examples of <em>group number</em> on the periodic table.
Explanation:
The table that consists of elements arranged systematically on the basis of atomic numbers is called periodic table. Groups and periods are two important part of a periodic table. A periodic table contains seven horizontal rows, called as periods and 18 vertical columns, called group.
The groups name is given in the form of number and alphabets. It represents the columns present in the periodic table.
Hence, 1 A, 3 B, and 7 A are examples of <u><em>group number</em></u> on the periodic table.

Answer:
E. The force on A is exactly equal to the force on B.
Explanation:
The force between two charges is given by
where
= Charge on particle 1
= Charge on particle 2
r = Distance between the charges
k = Coulomb constant = 
This force will be exerted on both the charges equally.
So, The force on A is exactly equal to the force on B
