The megaphone is cupping the area around her mouth and it is like with your hands, if you cover around them the noise will be louder. It is because it is hollow and there isn't anything to block the noise through the megaphone.
In the image below, the focus lines are shown. The step can be done to bring the apple into focus is make the lens rounder. The correct option is A.
<h3>What is lens?</h3>
The lens is in spherical shape may be diverging or converging.
As light enters the eye, it is focused on the retina. Changing the pupil diameter, regulates the amount of light entering the eye. Changing lens shape will focus the light.
The changes in lens shape needed to maintain focus as the object distance changes.
Thus, the correct option is A.

Answer:
The displacement is 6.71 [m} and the angle is 63.4° to the north of east
Explanation:
Using a sketch showing Dante's displacement, we can find each of the points Dante moves through. First, it moves 4 blocks east, the new coordinate (4.0), then moves 3 blocks south and we will get the new coordinate (4, -3). Then Dante moves 1 block west, thus the new point is (3, -3). And finally it moves 9 blocks north where the new coordinate in and gets -3 - (-9) = + 6.
The displacement can be found using the equation for the straight line.
We can realize that the triangle formed is a right triangle, therefore we can find the angle of the displacement.
No, because of that "seem" part of the question.
Your hearing system is not a linear sound detector and meter.
Sounds with equal amplitudes at different frequencies "seem"
to have different loudness, and the differences are different
for different people.
You've probably heard the saying "Things are not always as they seem."
The fact is, they NEVER are.
Because the specific metals aren’t mentioned in this inquiry.
The educational guesses that we can propose is that:
<span><span>1. </span>The
hypothetical inquiry: There are existing metals for making pots that will cook
food much faster.</span>
<span><span>2. </span>The
one-tailed alternative hypothesis: There are other metals for making pots that
will cook food much faster than the other metals.</span>
<span><span>
3. </span>The
one-tailed null hypothesis: All metals that are used in making pots will cook
food at an equal rate.</span>
