Answer:
It sounds fine, but it may be a bit too long. It's difficult to shorten things like this, but getting more straight to the point would give it that "catchy" feel.
Explanation:
Neutrons actually don't carry an electrical charge, which is why they are called neutrons because they are "Neutral".
Answer:
Lowering the object near the ground decreases its <u>potential energy.</u>
<u></u>
Explanation:
Potential Energy : Energy possessed by the object due to its shape ,Size and Position is called potential energy.
Example :
Change in shape and size : When you compress the spring , potential energy is introduced in it . So it expand quickly when you remove your hand.
Change in position : when you swing , after attaining maximum height (extreme ends) , the swing comes back on its on .This is because at maximum height ,the swing has<u> maximum Potential energy . </u>Hence it fall back on its on because it already has potential energy.
Potential energy(P) is given by the formula :
P = mgh
where ,
m= mass of the object
g = acceleration due to gravity
h = height of the object from the ground
If the height of the object increases from the ground , its potential energy also get increase.
<u><em>On lowering the object The height of the object from the ground reduces . So potential energy also reduces.</em></u>
D. How the pull of gravity has changed.
Answer:
Explanation:
Physical changes in cooking include the melting of solids, such as butter, and the boiling of liquids, such as water. Examples of physical changes would be the melting of fats and the boiling of water. Chemical changes involve the production of new substances.
