Answer:

Option C

Explanation:

Let the potential energy of rock A be represented as Pa

And the potential energy of rock B be represented as Pb

Pa = ma * g * h

Pb = mb * g*h

ma = 2 * mb

Thus, Pa = 2 mb * g*h

Pa/Pb = 2 mb * g*h/mb * g*h

Pa/Pb = 2

Pa = 2 * Pb

The energy pf rock A is two times the energy of rock B.

OR

Pb = Pa/2

Hence, option C is correct

Probable cause. An officer has reason to believe that a crime may be comitted. (physical evidence, observations, statements, video/audio.)

Searches. Officers are only allowed to do a pat down (terry search, frisk) as a protective measure. They can do a full search if a suspect is taken into custody.

4th amendment protects against unreasonable search and seizures.  

When a suspect is being questioned (for incriminating information) they must be read their Miranda rights before proceeding. Basic questions are allowed. ("How are you doing?").

Abuse of police authority could be requesting to see an ID when there is no probable cause.

It is not an economic activity - it's linguistic in nature, not economic.

It is not linguistics either - linguistics is a scientific discipline.

Alex files a petition for bankruptcy under Chapter 7. He owes $2.37 million to assorted creditors. Two months before filing, he
FrozenT [24]

Answer:

The trustee can stop Alex from selling the house and that automatically prevent the transfer of ownership from Alex to his brother Jonah.

Explanation:

The trustee will refute the transfer and take back the house as part of Alex's estate. The reason for this is not far fetched, Alex actions in this regards is tantamount to an abuse of chapter 7 of the Bankruptcy law. In that case, the trustees can use the "means test" to determine his actions and can stop the transfer of ownership to his brother, Jonah.

Because of people like Alex, US trustees has achieved a regulatory system most creditor friendly commentators have consistently espoused, which is a formal means test for Chapter 7. (The Bankruptcy Abuse Prevention and Consumer Protection Act of 2005) has clarified this area of concern.

When a new president comes into office, does the military face any changes to how it was before?
Travka [436]

Answer: Certain changes are possible, but the essence remains the same.

Explanation:

The new president may bring some military changes, but the essence of the United States military remains the same. Thus, the president can appoint to certain high positions in the army if he wants new people. All the changes brought about by the new president do not significantly change the essence of the military forces in the country. Following that, we can cite one example that is currently current. Namely, many military analysts and media in the United States state that the new President of the United States, Joe Biden, will withdraw the still incumbent President Donald Trump's decision on how transgender people cannot be part of the armed forces.
