Answer:
Force on the object is 20 N
Explanation:
As we know that work done to raise the book from initial position to final position is known as potential energy stored in it
So here we know that
here we know that
U = 30 J
s = displacement = 1.5 m
so we have
Answer:
yo they deleted my answer. The answer is 0N
Explanation:
so when two forces pull on an object from opposite sides with the same force (in this case its 20N), then the object is in equilibrium at 0N.
So its clear that there is one person on the the opposite side.
SOOO generally<u>: (left or down) would be considered </u><u>negative</u><u> in an equation. And the other person (right or up) would be considered </u><u>positive</u><u>.</u> So if both forces are the same numbers on opposite sides then the answer is 0 (if you add both of them).
<em>0 is the number of equilibrium.</em>
OK, so the equation would be -20N + 20N and then badda bing badda boom viola, the answer: 0N
thanks for coming to my TED talk. I hope they don't delete this answer.
As per question the initial states of the gases are given as
INITIAL STATE: FINAL STATE:
![v_{1} =v[say]](https://tex.z-dn.net/?f=v_%7B1%7D%20%3Dv%5Bsay%5D)
![v_{2} =3v[say]](https://tex.z-dn.net/?f=v_%7B2%7D%20%3D3v%5Bsay%5D)
AS per combined gas equation obtained from the combination of Boyle's law and Charles law [Basic ideal gas laws]
Hence 
=
=190.3 K [ANS]
Atomic mass = protons + neutrons
So the total number of protons and neutrons
Answer:
0 111.0N be cause the rest do not add up
