Answer: true
Explanation: I got the question and guessed true and it was right
Answer:
yes
Explanation:
I think so because it not mention in the law
Answer: Option (c) is the correct answer.
Explanation:
Physical properties are the properties in which there is no change in chemical composition of a substance. On the other hand, chemical properties are the properties which change the chemical composition of a substance.
For example, when water boils at then it changes into vapor state whereas when water freezes at then it changes state from liquid to solid.
This means only physical state of water is changing and there is no change in chemical composition of water.
Hence, we can conclude that best option describing given information is that these are the physical changes water undergoes.
<span>According
to the special theory of relativity, all laws of nature
are the same in
reference frames that move at constant speeds.
That means that there's no test or measurement you can do to
detect whether you're moving at a constant speed</span> or how fast.
And THAT means that there's no such thing as "who's REALLY
moving" and "who's REALLY at rest". There's no such thing as
"real" motion, only motion relative to something else.
Answer:
Radius of aluminium sphere which has same mass as of sphere of iron with radius 14 m is 40.745 meters.
Explanation:
Let the radius of aluminium sphere be
From the relation between density, mass and volume we know that
Applying equation 'i' separately to iron and aluminium sphere we get
Equating the masses of iron and aluminium spheres we get
