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

Afina-wow [57]

The false statement about John B. Watson is the one that says that he worked with Edward C. Tolman to prove that fear is both an instinct and a reflex.

Although he worked on the subject through the Little Albert Experiment, he did not work with Edward C. Tolman but with Rosalie Rayner, his assistant and later couple.

In the experiment, Watson intended to demonstrate how the principles of classical conditioning, which had just been raised by Ivan Pavlov in those years, could be applied to a child's fear reaction to a white rat.

A reason not to view prostitution as simply a matter of personal choice involving adults is that
GrogVix [38]
Prostitution is legal in some countries, yet illegal in other countries. It can be viewed not as a matter of personal choice if the situation is seen in the perspective of the law, or rather, is seen in a legal perspective. If prostitution is illegal, then personal choice should not be held as an answer for choosing prostitution. The law says that it is illegal, and therefore, personal choice does not legalize prostitution in any way.

natka813 [3]

Answer:

The best answer to the question: To remember the address, you used a(n): control, process in STM (Short term memory).

Explanation:

In humans, memory can be divided into two groups: short-term memory, sometimes known as working memory, and long-term, or permanent, memory. Unless information taken in by the brain, and related to memorization, is managed and controlled in a specific way, it will be released and forgotten, or as we normally call it, erased. The use of control processes, such as the one used by you to memorize the address, and then be able to think about something else, without forgetting the memorized piece of data, will ensure that short-term memory actually saves the data and makes it available for retrieval without difficulty. In fact, it is known that control processes are vital for short-term memory, to control the process of learning and forgetfulness, as well as to balance the process of decision-making and the flow of information inside the brain.
