For machines such as a rake the output force is less than the input force. If the input force of the rake is 10 newtons and the output force is 5 Newtons mechanical advantage is .5
Answer:
The original number of oxygen atoms was about 80 times larger than Avogadro's number. Since each sulfuric acid molecule contains 4 oxygen atoms, there are about 20 moles of sulfuric acid molecules.
Answer:
The best available answer here is particle velocity equals the boiling point.
Explanation:
The element with the lowest melting point is Ga.
Hence, Option (C) is correct answer.
<h3>What is Melting point ?</h3>
Melting point is usually defined as the temperature at which solid changes to liquid.
<h3>What is the order of melting point of B, Al, Ga, Tl ?</h3>
The melting point order of B, Al, Ga, Tl is B > Al> Tl > Ga due to structural changes, melting point increases from Ga to Tl. Hence Ga has the lowest melting point among all these.
Thus from the above conclusion we can say that The element with the lowest melting point is Ga.
Hence, Option (C) is correct answer.

Answer:
d. End product is that product with a ketone and carboxylic acid.
Explanation:
Sodium borohydride is a reducing agent, it reduces the ketone to a primary alcohol.
Then acidified water is an oxidising mixture which reverses the reduction reaction.
