Answer : The volume of engine in cubic inches is, 
Explanation :
As we are given that the volume of engine is, 7.0 liters. Now we have to calculate the volume of engine in cubic inches.
Conversion used :

So, 

or,


As,

So,

Thu, the volume of engine in cubic inches is, 
The "Black Hole" gets its name from the astronomical amount of gravitational force created by the black hole. This gravitational force is so great that even light cannot escape it, hence, it is completely black
Answer:

where , F = Gravitational force
G = Gravitational constant
= mass of first object
= mass of second object
r = distance between the two objects
As Gravitational force is inversely related to the distance between two objects, lesser is the distance , more will be the gravitational force. As distance between C and D is more , the force shoulld have been less. That means the product of the masses of the objects C and D is more than the product of the masses of the objects A and B.
Answer:
Option (4)
Explanation:
Waves are generally caused by the wind that blows over the oceans. The waves formed by the wind are known as the wind driven waves. They are also known as the surface waves. When the wind blows over the surface of the ocean water, it creates a friction between them, as a result of which these surface waves are generated. This wind as well as the pressure differences below the ocean surface provides energy to the ocean waves. These waves are constantly moving in all the parts of oceans and are affected by the Coriolis force that results due to the rotation of the earth.
Hence, the correct answer is option (4).
