Nuclear size are measured in a unit called fermi
Magnetism at the centre of a bar magnet is zero, because there is no magnetism at all in the centre
Hope this helps :)
<h2>Right answer: Sea breeze </h2>
The sea breeze is formed because during the day the surface of the land on the coast tends to warm up before and more than the surface of the sea. This difference in temperature between these two air masses means that on a sunny day the land warms up much more than the ocean causing a small area of low pressure.
Then, the air rises as the land warms it and the colder air located on the surface of the sea forms a high pressure zone that makes this air mass tend to occupy the space left by the warmer air that has ascended on the coast. Therefore, the mass of air of a high pressure on the ocean always tends to move towards the zone of low pressure located on the coast.
It is important to note that the <u>sea breeze blows perpendicularly to the coast</u> and that the best breezes are formed in the spring and summer seasons because during the spring the water temperature is still cold and during the summer the sun produces high temperatures over the land in the coast.
<h2>So, <u>
the greater the temperature contrast </u>
between the land and the sea, <u>
the greater the force of the wind generated</u>

Just assume that the sun has the average mass of all the stars
Then divide the mass of the galaxy by the mass of the sun.
<span>10^30 has 30 zeroes after it. 10^42 has 42 zeroes.
The answer would have 12 zeroes which concludes a trillion stars. </span>
Answer:
a=2.304×10¹⁶m/s²
Explanation:
Given data
Distance d=2.5 nm=2,5×10⁻⁹m
Mass of proton m=1.6×10⁻²⁷kg
charge of proton q=1.6×10⁻¹⁹C
To find
acceleration a
Solution
Apply the Coulombs Law
Where k is coulombs constant (k=9×10⁹Nm²/C²)
q=q₁=q₂
r=d
So
Answer:
2,8
Explanation:
The first electron shell would have 2 electrons, the second shell would have 8 electrons. This is because Neon has a relative charge of 10.
