Consider an electromagnetic wave propagating through a region of empty space. How is the energy density of the wave partitioned
Zepler [3.9K]

Answer:

Option (2) is correct.

The energy density of an electromagnetic wave is equally divided between the magnetic and electric fields.

Explanation:

An electromagnetic waves are the waves which are produced when the oscillating electric and magnetic field are interact each other perpendicular to each other. The direction of propagation of electro magnetic waves is perpendicular to each electric and magnetic fields.

The energy associated with the electromagnetic waves is equally distributed in form of electric and magnetic fields.

So, the correct option is (2).

Inertia is directly related to Mass .

<u>Explanation</u>:  

Mass means that the amount of matter of an object. Inertia indicates the resistance of the physical object. The object with high mass have more inertia too. The mass and inertia both are directly proportional to each other. Mass is the quantity that completely depends upon the inertia of the object. An object with more mass has more chance to change its resistance as they are dependent on each other.

In a random sample of 200 students from Northern State University, 150 said that they own an Therefore, probably at least 50% of
kirza4 [7]

Answer:

No fallacy

Explanation:

The statement that at least  50% of the students at Northern State own an iPod is best categorized as no fallacy.

This statement is very true and consistent with the facts presented in the passage.

A fallacy is a mistaken belief usually based on biased arguments.

Total number of students sampled = 200

Number of iPod owners = 150

Percentage of iPod owners = \frac{number of iPod owners}{Number of sample} x 100

Percentage of iPod owners = \frac{150}{200} x 100 = 75%

We see that it is consistent to say that at least, 50% of the students in the sample are iPod owners.
