Rocks A and B are located at the same height on top of a hill. The mass of rock A is twice the mass of rock B. How does the potential energy of rock B compare to that of rock A?
A. Rock B has the same potential energy as rock A.
B. Rock B has one-quarter the potential energy of rock A.
C. Rock B has one-half the potential energy of rock A.
D. Rock B has twice the potential energy of rock A.

Answers

Answer 1

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

Write a Informative essay explaining the impact of music on humans.

Answers

Answer:

Explanation:

Music can help people in many ways. Music is known to help people with memory and language problems by helping them remember and learning how to speak again. It can also improve your health and productivity and it serves as a form of expression, as well as a way for teenagers to understand and identify some emotions that they might be feeling. Listening to music is also good for people who are under a lot of stress, so they can relax and sleep better. Because taking music lessons can also improve many skills, it’s recommendable to get involved with it to help yourself in school or work. For patients with mental illnesses, like Alzheimer's and dementia, taking music therapy can be really helpful mentally, physically, and emotionally. Musicians have a better memory than people who don’t know how to play an instrument. This is because their training gives them a high working-memory brain. Having this is good because it enhances thinking and concentration, and you develop better listening abilities. Music training can improve verbal memory and attention.

They were military boarding schools designed to train the future leaders of the Chinese Communist Party.
They were small-scale farming and industrial communities in which thousands of individuals lived and worked.
They were labor camps organized to contain political opponents and any individuals convicted of a capital offense.
They were unions established through the government to allow workers to negotiate wage increases and file complaints.

Answers

Answer:

See below

Explanation:

From the definitions, it is definitely the second, although I would question the term small-scale.

Under Mao Zedong’s Great Leap Forward program there were small-scale farming and industrial communities in which thousands of individuals lived and worked. Hence, option C is appropriate.

Who was Mao Zedong?

Mao Zedong, often known as Chairman Mao, was a Chinese communist revolutionary who founded the People's Republic of China. From the PRC's founding in 1949 until his death in 1976, he served as the party's leader.

Maoism is a variety of communism that he (Mao Tse Tung) created. It is a theory to seize State power via a mix of violent rebellion, widespread mobilization, and tactical partnerships. The Maoists' insurgency strategy also includes propaganda and misinformation against State institutions.

More people perished from starvation between 1960 and 1962 in China than during any other single famine in recorded human history, according to estimates. Tragically, this catastrophe could have been avoided in a major part.

Hence, option C is correct.
