The paper clip, which is denser than water, floats on the surface because of water's surface tension. Surface tension is a property of water that is the result of polar water molecules sticking together or water's property ofA)
adhesion.
B)
cohesion.
C)
buoyancy.
D)
capillary action.

Answers

Answer 1
Answer: The answer is cohesion. The high surface tension helps the paper clip (with much higher density) float on water. The property of a liquid that allows it to resist an external force, due to cohesive nature of its molecules. Cohesion refers to the attraction of molecules for molecules of the same kind. Water molecules have strong cohesive forces due to their ability to form hydrogen bond with each other.
Answer 2
Answer:

Answer:

The answer is cohesion.

Which of the following sets is an infinite set?A.){1, 2, 3 . . . 100}
B.)empty set
C.)the set of whole numbers less than one billion
D.)the set of natural numbers
E.)none of the above

Answers

Answer: the correct answer is D) The set of natural numbers.

A set that contains infinite number of elements is called as infinite set.

Natural numbers are those that start from one and go till infinity. Thus, set of natural number is infinite as this set contains infinite number of elements, satisfying the property of infinite set.

On the contrary, option A), B), and C) contains finite numbers, which can be counted. Thus, they are not the example of infinite set.

Thus, D) is the right answer.

Answer;

D.)the set of natural numbers

Explanation;

-A set is said to be an infinite set whose elements cannot be listed if it has an unlimited (i.e. uncountable) by the natural number 1, 2, 3, 4, ………… n, for any natural number n is called a infinite set. A set which is not finite is called an infinite set.

-Set A cannot be infinite because it only goes to 100 and Set B is empty so that also has nothing infinite. However set of Natural numbers as they continue number by number getting in to an bigger number is infinite.

-On the other hand; A set is said to be a finite set if it is either void set or the process of counting of elements surely comes to an end is called a finite set.
