Explanation:
P.E=MGH
(1) P.E=5×10(G)×3
= 150 kg m^/s^ ( ^ =sqaure)
(2) P.E=5×10×6
= 300 kg m^/s^
Hope it helps, just remember the formula u can solve any question regarding gravition of earth (P.E=Mgh)
We’ve all noticed that science has been accelerating and a very fast rate resulting in what has been called information overload and more recently filter failure. There are now more researchers add more papers than ever which has led to the importance of bibliometric measures Bibliometric as a Field is a fairly new discipline but it has seen in impressive growth in years due to computation and data storage. Journal metrics can play an important role for editors. There are many different metrics
First, we need to convert the pressure in SI units. Keeping in mind that

:

The initial and final volume of the gas are (keeping in mind that

):


So, the work done on the gas by the surrounding is

And the final positive sign means that this work corresponds to an increase in internal energy of the gas.
It is the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
The answer is A. When the forces are weaker, they will not be able to hold the particles of the substances together; therefore, the substance will be observed as being volatile.
