Question:

How can you learn to pronounce the letter غ (ghayn) if you were never born with the Arabic tongue? I tried so many times but I can't do it.

The best method I found that it helps students pronounce that letter is the following: - Pick up a cup of water and gargle while making a note of where the gargling sound is coming from. Do that a few times and try to remember. - Now to try to make that gargling sound again without using water - repeat that a few times to train your brain, because this is mostly an exercise for your brain!

Question:

If a bird has to feed its chicks 3 times a day, and the distance from the nest to the source of food is 300 m, what is the total distance the bird travels every day (starting from the nest)?

Nest --> Food source: 300 m Food source back to nest: another 300 m So total of 600 m for every round trip. Total distance per day = 600 m x 3 = 1800 m

Question:

What does an electron look like?

Abdelrahman E.

We don't know what it really looks like. You can't see an electron under a microscope the same way we can see a dust particle, this is partly because of the peculiar properties of an electron behaving as both a particle (with a mass about 2000 times smaller than a proton) and a wave. We use mathematical models to help us understand how an electron behaves. For example, in an atom, the electron orbital is modeled as an electron cloud surrounding the nucleus. The space between the nucleus and the electron is huge. It is like an athlete (the electron) running very wide circles around a huge empty field with a tiny grain of sand in the center (the nucleus).
