Answer:D
Explanation:
Heisenberg’s uncertainty principle in quantum physics by German physicist Werner Heisenberg in 1927 states that the more accurately the velocity of an object (electron) is determined , the less accurate the position of the object is known and vice versa. The principle talks about how difficult it is to determine the precision of two related parameters.
Answer:
Option B. inertia
Explanation:
Inertia can be explained as the property of a body due to which the body resists any change in its form or shape.
The given case complies with Newton's first law or Law of inertia which says_ a body in motion will remain in that state of motion or at rest will continue to be in that stationary until it comes under the action of some external force.
Therefore, a meteor moving through outer space will continue on that path until acted upon by an external force.
The parts of the cell are mitochondria, lysosomes, ribosomes etc. Their functions are as follows :
(1) Vesicle is a one of the large structure within the cell. Its function is to transfer materials out of the cell.
(2) Mitochondria is also called the power house of the cell. Its function is to break down sugar to supply energy for the cell.
(3) Lysosomes are the suicidal bag of the cell. It breaks down waste and other materials of the cell.
(4) Endoplasmic reticulum helps to produce, process and transport proteins in vesicles to the Golgi apparatus.
<u>Answer:</u>
<em>Equivalence point and end point are terminologies in pH titrations and they are not the same.
</em>
<u>Explanation:</u>
In a <em>titration the substance</em> added slowly to a solution usually through a pippette is called titrante and the solution to which it is added is called titrand. In acid-base titrations acid is added to base or base is added to acid.the strengths of the <em>acid and base titrated</em> determines the nature of the final solution.
At equivalence point the <em>number of moles of the acid</em> will be equal to the number of moles of the base as given in the equation. The nature of the final solution determines the <em>pH at equivalence point. </em>
<em>A pH less than 7 will be the result if the resultant is acidic and if it is basic the pH will be greater than 7. </em>In a strong base-strong acid and weak base-weak acid titration the pH at the equivalence point will be 7 indicating <em>neutral nature of the solution.
