Answer:
All objects that have balanced forces acting on them must be stationary is an example of Newton's first law of motion.
Explanation:
- Newton's First law of motion is the Law of inertia, that states a body continues to be in state opf rest or state of motion untill an unbalanced force acts on it.
- So if a body has all balanced forces acting on it then it will continue to remain in state of rest i.e. it will be stationary.
- The first example describes Newton's third law, that every action has equal and opposite reaction.
- The second and third example supports Newton's Second Law, the law of momentum which states that the rate of change oif momentum is directly proportional to the force applied on the body and the mass of the body.
Answer:
This can be evaluated with DNA test- by comparing the mitochondrial DNA (mtDNA)of the Tsar family with the woman-Anastasia. <u>Maternal DNA is inherited uninterrupted from generation to generation
</u>
Explanation:
The living consort of Queen of Elizabeth ,Prince Philip, <u>is a grand nephew of Tsar Nicholas 11.</u> They shared the same maternal ancestry.
Therefore, his mitochondrial must be maternal, and compatible with that of the Tsar Nicholar. Male children always inherit maternal mitochondria (mtDNA)and passed from generations to generation.
T<u>he blood samples of prince Philip can be taken, to extract the mtDNA,and matched with the sample of mtDNA obtained from the exhumed bodies of the Tsars,</u><u> </u>to reaffirmed the compatibility of the ancestry .
If sample of the compatible mtDNA, from price Phillip was compared with the mtDNA of the woman who claimed to be Anastasia, her claim can be validated.
Matched sample shows she was the daughter, while negative result proves otherwise.
