Answer:
it would have potential energy
$34.75 per month
It is a trick question at the end because it says that anything over 250 kwh is $0.03. Although, you are only calculating for 180 kwh and the monthly charge.
As we know that friction force on box is given by

here we know that

here we have
m = 12 kg

so now we have

now we will have


so it required minimum 49 N(approx) force to move the block
Answer:
Option C. be frozen at 12 noon
Explanation:
This can be explained by the special theory of relativity according to which at greater speeds time slows down and length contracts in the direction of motion.
Also if a body travels at the speed of light time will stop and the body will will reduce to zero length.
Therefore, for the given case time will freeze at 12 noon.
Answer: Option (B) is the correct answer.
Explanation:
When model B shows three dimensional shape of the molecule then it becomes easier to visualize the exact shape or geometry of the molecule as we get to know how atoms are bonded together.
Therefore, with the help of this it would be easy to know the hybridization of molecule. Basically, we will get to know the type of molecule represented by model B.
Thus, we can conclude that the statement Model B shows the three-dimensional shape of the molecule, but Model A does not represents Model B better than Model A.
