Answer:

Lobotomies were initially developed to destroy the part of the brain that controls emotions.

Explanation:

Lobotomy is a psychosurgery that involves cutting nerve fibers in the brain. The lobotomy was based on the idea that mental illnesses can be cured by changing the way the brain works. It was believed that changing connections with the frontal lobes could change emotions without affecting intelligence. The most common procedure was the introduction of a sharp tool to reach the frontal lobe of the brain through the eye.

Lobotomy attempts to change the connections of white matter into gray matter. White matter has the nerve fibers that connect gray matter, which includes neurons or brain cells, and carry messages with electrical impulses.

Finally, lobotomies were initially developed to destroy the part of the brain that controls emotions.

A ball is whirled on the end of a string in a horizontal circle of radius R at constant speed v. Which way(s) can increase the c

Sav [38]

Answer:

A, B and F are the right answers

Explanation:

The formula is $a_{c} = v^{2} / r$

A) Increasing both the radius and the speed by a factor of 9

$a_{c} = (9v)^{2} / (9r)$ = $9v^{2} / r$

which means the acceleration will increase by a factor of 9

B) Keeping the speed fixed and decreasing the radius by a factor of 9

$a_{c} = (v)^{2} / (r/9)$ = $9v^{2} / r$

which means the acceleration will increase by a factor of 9

C) Keeping the radius fixed and increasing the speed by a factor of 9

$a_{c} = (9v)^{2} / (r)$ = $81v^{2} / r$

It will increase the acceleration 81 times

D) Keeping the speed fixed and increasing the radius by a factor of 9

$a_{c} = (v)^{2} / (9r)$ = $v^{2} / 9r$

It will decrease the acceleration by 9 times

E) decreasing both the radius and the speed by a factor of 9

$a_{c} = (v/9)^{2} / (r/9)$ = $v^{2} / 9r$

It will decrease the acceleration by 9 times

F) Keeping the radius fixed and increasing the speed by a factor of 3

$a_{c} = (3v)^{2} / (r)$ = $9v^{2} / r$

It will increase the acceleration by 9 times

3 Below, someone is trying to balance a plank with

belka [17]

Answer:

a. The moment of the 4 N force is 16 N·m clockwise

b. The moment of the 6 N force is 12 N·m anticlockwise

Explanation:

In the figure, we have;

The distance from the point 'O', to the 6 N force = 2 m

The position of the 6 N force relative to the point 'O' = To the left of 'O'

The distance from the point 'O', to the 4 N force = 4 m

The position of the 4 N force relative to the point 'O' = To the right of 'O'

a. The moment of a force about a point, M = The force, F × The perpendicular distance of the force from the point

a. The moment of the 4 N force = 4 N × 4 m = 16 N·m clockwise

b. The moment of the 6 N force = 6 N × 2 m = 12 N·m anticlockwise.

The importancê òf measurement

dem82 [27]

Measurements in physics is important because it enables people to argue using mathematics where numbers can be used to represent knowledge in a convenient manner when we show and communicate about a phenomenon.

Explanation:

When a physician is able to measure a phenomenon, then we get a foundation of understanding a lot of things in our universe.Measuring these things will help know how to use them in various applications.
