The mechanical energy of an object is equivalent to the sum of its potential and kinetic energy. If the helicopter is grounded, then its mechanical energy will be 20 J. If it is in the air, then its potential energy will be calculated using:P.E = mghAnd then added to the kinetic energy to obtain mechanical energy.
Answer:
A. Murder.
Explanation:
The given situation describes that it is a murder case as the husband fired to the neighbor by a single shot which is totally unlawful as the husband needs to talk to his wife and neighbor to settle this and threaten him too far away from his wife.

But he should not shot him as his life would be destroyed due to anger he took this step.
Therefore this is the case of murder.
Answer: A: The current selling price matches the product's equilibrium price.
Explanation:
The graph is attached for a better analysis.
From the graph, we can see that the Equilibrium price is $400 while the equilibrium quantity supplied and Equilibrium quantity demanded is 4000.
Since the current selling price is $400 and the equilibrium price is $400 as well, then we can say that the current selling price matches the product's equilibrium price.
Therefore, the correct option is A.
Ford put finishing touches on his pure ethanol-powered motor.
