Answer:

It is a copy of an object and appears to be coming from behind the mirror.

Explanation:

  1. The plane mirror has a flat surface, where of its surface is polished to reflect the light.
  2. The plane mirror shows the image as the same size of the object.
  3. The image produced by the plane mirror is virtual and erect.
  4. But the orientation of the image formed changes the left and right.
  5. Hence,the image appears to be coming from behind the mirror.

Ocean waves are traveling to the east at 4.9 m/s with a distance of 23 m between crests. (b) With what frequency do the waves hi
ser-zykov [4K]

Answer:

0.26086 Hz

Explanation:

solution:

The relative speed of the wave is:

v = 4.9+1.1 = 6 m/s

the frequency is:

f = v/λ

 = 6/23

 = 0.26086 Hz

Dolphin echolocation is similar to ultrasound. Reflected sound waves
s344n2d4d5 [400]

Answer:

Waves with high frequencies have shorter wavelengths that work better  than low frequency waves for successful echolocation.

Explanation:

To understand why high-frequency waves work better  than low frequency waves for successful echolocation, first we have to understand the relation between frequency and wavelength.

The relation between frequency and wavelength is given by

λ = c/f

Where λ is wavelength, c is the speed of light and f is the frequency.

Since the speed of light is constant, the wavelength and frequency are inversely related.

So that means high frequency waves have shorter wavelengths, which is the very reason for the successful echolocation because waves having shorter wavelength are more likely to reach and hit the target and then reflect back to the dolphin to form an image of the object.

Thus, waves with high frequencies have shorter wavelengths that work better  than low frequency waves for successful echolocation.

Which lists the main components of Darwin’s theory of evolution?
Nataliya [291]

Hi!


The correct option is B.


<h3>Explanation</h3>

Evolution is a biological phenomena which descries how the heritable characteristics of a species change over successive generations. These characteristics change as a result of a mutation, natural selection or genetic recombination (to list a few).

Darwin's theory of evolution explained how this phenomena occurs with respect to natural selection. The theory goes on to explain how a species diverges from a common ancestor into two or more different species (meaning different species may have common ancestor). This is a slow process as it can take thousands of years.


Hope this helps!
