<span>So the question is how can a spoon sound like a bell. Sound waves are mechanical waves that have their frequency. When a source, in this case a spoon and a bell oscilate, they produce sound waves. If they produce those sound waves in the same frequency, then we can say they produce the same tone thus they sound the same.</span>
Here the right answer
The motor is connected to a battery. When the switch is closed, the current starts<span> to flow and the coil becomes an electromagnet. In this case the current is flowing </span>anticlockwise<span> in the top of the coil. This makes the top a </span>north<span> pole. This north pole is </span><span>attracted </span><span>to the south pole on the left. So the top of the coil </span>turns<span> towards the left. Notice that the bottom of the coil is a </span>south<span> pole and is attracted to the magnet on the right. Hope this helped</span>
The corona of the sun is the outermost layer of the sun. The temperature of the corona is approximately 500,000 to 2,000,000 degrees kelvin (based on calculations of NASA).
Corona cannot be seen with the naked eye except during the time of the solar eclipse. The reason why the temperature of the corona is higher than that of the surface of the sun is still an unsolved mystery.
Hello!
This is the best answer i could possibly think of i hope it helps you out!
As the water cools freezes into ice, it becomes less dense. On the other hand, most substances are most dense in their solid state than in their liquid state. For an object to be able to float, it has to displace a weight of fluid equal to its own weight. The heavier water displaces the lighter ice, so ice floats to the top.
