Answer: 1970s

Explanation: The prevailing model for planetary acceleration also known as the fractal assembly dating back to 18th century assumes that the solar system is made up of small grains striking each other chaotically into bigger ones, to form planetesimals.

Plastesimals then collide to form planets. This model was proposed  by Russian astronomer Victor Safronov  and it was further translated in English in 1970s by George Wetherill.

This remained same for almost next 40 years.

As a rat is taking a drink of green, licorice-flavored water, it receives a painful tail-pinch. The next day it is given a choic
Pavlova-9 [17]

Answer:

The rat will most likely take more of the licorice flavored water

Explanation:

The rat will take more keen on taking more of the licorice flavored water than green water because it has associated the taste of the green water with painful pinch it received on the tail, causing it to refrain the next time it has a choice.

In behavioral psychology, animals are known to tie their actions to either pleasurable or painful feelings. Naturally, the behavior of every animal is conditioned in such a way that it seeks pleasure and avoids pain.

Once the rat begins to associate the taste or sight of the green water with pain, it abstains.
