Answer:
a), b), d), and e) are correct.
Explanation:
c) is incorrect because an object that has a definite shape cannot be in a gaseous state as gaseous objects take the shape of their container.
a) is correct because objects that are liquid have definite volumes but no definite shapes as they take the shape of their containers,
b) is correct as this is the definition of an object which is in a solid state.
d) is correct as this is the definition of an object which is in a gaseous state.
e) is correct as rigidness, the quality of having a definite shape is only exhibited by objects that are in solid state.
When the two forces of gravity and air resistance become the same, the object no longer speeds up, and it doesn't slow down either. This is called terminal velocity
So the answer is b
1.) when the distance between the two objects is dubled then the gravitational Force btw them is <u>reduced by 4 times</u> I.e it becomes 1/4 of original due to the <u>inverse square law.</u>
2.) because the distance from the center of earth and pole is less then the distance btw pole and equator that's why due to <u>inverse square law</u> .
the gravitational Force on object at equator is less then the object on poles.
Answer:
<em>1. Genetic diversity</em> are the differences in DNA among individuals within a species or population while <em>ecosystem diversity</em> is the number or variety of ecosystems within a particular area.
2. <em>Genetic diversity
</em> is the genetic material of microorganisms, plants and animals contains information that determines the characteristics of all species and individuals that make up the diversity of the living world while the <em>ecosystem diversity</em> is the enormous range of terrestrial and aquatic environments on earth has been classified into a number of ecosystems.
