Explanation:
v = wavelength x frequency
330 = 5 . 10-² m x f
f = 6600 Hz
the frequency that human can hear is about 20 Hz - 20000 Hz
so human can hear the note.
The compass is designed and developed to use a pendulous system to improve horizontality.

To be able to identify that the object is in the same motion, we should find the graphs that has an increasing slope of displacement and with the constant velocity with varying time. Graphs on letter D satisfies these requirements.
<em>ANSWER: D</em>
Electromagnetic waves can travel through a vacuum. Because they do not give up energy
in traveling, Electromagnetic waves can cross the great distances that separate stars
and galaxies. Rays from the Sun travel nearly 150 million
kilometers to reach Earth's surface.
The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. The air over the ocean is now warmer than the air over the land.
not giving you the answer but hopefully this gives a hint
