Answer:
Thickness of each page will be 0.00785 cm
So option (E) will be correct answer
Explanation:
We have given that last page on the book is numbered as 764
So total number of pages in the book ( as each page is numbered in both side )
Total thickness of the book = 3 cm
We have to found the thickness of the each page
So thickness of each page will be
So option (E) is correct option

Answer: The horse is moving with a uniform acceleration
Explanation:
According to the described situation, we are dealing with a <u>constant acceleration</u> (also called <u>uniform acceleration</u>), since the horse's velocity is changingn by a constant rate.
Let's prove it:
Firstly we are told the horse follows a straight path. In addition we are given its velocity:
3 m/s, then 4 m/s and 5 m/s
Since acceleration is defined as the change of velocity in time we can calculate it:
This is the horse's constant acceleration
Answer:
One-fourth of the original gravitational force.
Explanation:
The gravitational force between two objects of masses is given as:
Where,
Therefore, the gravitational force is inversely proportional to the square of the distance between the masses.
Now, if the distance is doubled, then the force has to be reduced by a factor of one by four or gravitational force will one-fourth of the original.
Let us verify it.
If , then new gravitational force is,
As seen above, new gravitational force is one-fourth of the original gravitational force between moon and Earth.
