Answer:

Las Zonas de Expansión son aquellos lugares donde las placas de la corteza terrestre se están separando, impulsadas por las corrientes ascendentes del manto superior, dando lugar a la salida de magma procedente de interior.

Explain why an object moving in

vazorg [7]

An object moving in a circle is accelerating, even if it moves with a constant speed because the velocity changes.

Explanation:

The direction of an object changes constantly during its movement in circle at a constant speed. As the direction changes it results in changing the velocity of that object. This happens since velocity has direction and magnitude.as it is vector quantity.

An object will have acceleration only if a resultant force is acting on that body. When an object is moving in a circle, this resultant force is the centripetal force that is acting towards the center of the circle.

The inner planets mercury, Venus, earth, and mars were formed by

VikaD [51]

ANSWER:

About some billion years ago, dust and gas particles began orbiting around the sun.

These particles then began to stick together and formed large particles. Slowly, these particles began attracting more mass with their gravity.

After millions of years, these particles became planetesimals. They started revolving around the sun in their own orbit and formed spherical shapes.

This continued for another millions of years and thus planets were formed.

EXPLANATION:

The inner planets are the four planets that are closest to the sun. The inner and outer planets are separated by asteroid belts.

The "inner planets are terrestrial" and rocky whereas the "outer planets" are mostly gas.

Why has the Ugandan government pushed Abstinence as a means of combating the spread of HIV/AIDS?

Sholpan [36]

Answer:

According to (hrw dot com) the “Abstinence-Only HIV/AIDS Programs” in Uganda in the early 200x is called The Less They Know, the Better. Why the people there do not need to know so much about HIV, but they need just to follow the Abstinence ? “We don't think abstinence is really working in our communities. We work with children in primary five through seven who are engaging in sexual activities. We always come with the message to delay sexual debut. But for most children here, this is not enough.” - The youth leader of the program said.

So, the main reason why has the Ugandan government pushed Abstinence as a means of combating the spread of HIV/AIDS is: the people for whom the propaganda is done are mostly children above 10, who tend to start having sex at an early age. Uganda is home to nearly 1 million children orphaned by HIV/AIDS, many of them at high risk of HIV infection themselves.

“Abstinence Until Marriage" is the meaning of the Abstinence-Only HIV/AIDS Programs. The content of the propaganda is teaching that abstaining from sex until marriage is the only effective method of HIV prevention and that marriage between a man and a woman is the expected standard of human sexual behavior.

The other reasons are:

- Demographic and health surveys show that over half of Ugandan girls have had sex by age seventeen, usually with someone older.

- Among girls who marry before the age of eighteen, most marry men who have been sexually active for several years, often without having used condoms.

And there is the biggest problem for Uganda related to poverty: Ss in all countries, AIDS in Uganda is a disease of poverty. Many Ugandans live on less than U.S.$1 per day, a situation that has been exacerbated by decades of political violence and civil war. New HIV cases occur among girls trading sex for school fees, women enduring violent marriages because they lack economic independence, and orphans being pushed onto the street and sexually exploited.

Find an equation for the perpendicular bisector of the line segment whose endpoints

zzz [600]

Answer:

y= -7/2x-26/2 or y= -7/2x-13

Explanation:

To solve this question you need all of these formulas:

gradient: $\frac{y2-y1}{x2-x1}$ , Point-Slope $y-y1=m(x-x1)$ ,

perpendicular m $(m1)x(m2)=-1$ , Midpoint $(\frac{x1+x2}{2}$ , $\frac{y1+y2}{2} )$

and equation of a line $y=mx+c$

where m stands for gradient

First things first.

To start you have to know the data of the line that includes the two endpoints, so you calculate its gradient (m) of this line with the gradient fromula: $m=\frac{-4-(-8)}{5-(-9)}$ , which equals 4/14 or 2/7

(It can also be called rise/run) (Remember the rule of signs where - and - equal +)

with that information you can proceed with the point-slope or point-gradient formula, so you plug the values: y-(-8) = 2/7 (x-(-9)), which results in y+8=2/7(x+9) and then y+8=2/7x+18/7.

To finish the equation you move eight to the other side. To simplify things you can change it into a fraction as I did, and remember to change signs.

y=2/7x+18/7 -8 -> y=2/7x+18/7-56/7 . This gives us the number of y=2/7x-38/7, which is the equation of the first line.

Now to know the gradient of the second line you apply the formula of perpendicular bisector where m1 x m2 = -1. We know m1 (gradient of the first line) is 2/7, so m2 = $\frac{-1}{2/7}$ = -7/2. m2 is therefore -7/2

Now you have to know the midpoint between the two endpoints, which will act as the start point of the perpendicular bisector

M (midpoint) = $(\frac{-9+5}{2} ,$ $\frac{8+(-4)}{2} )$ , which give us the coordinates of (-2, -6)

(remember, x coordinate is always first)

with this point we can apply again the point-slope formula to know the equation of the line:

y-(-6)=-7/2(x-(-2)) -> y+6=-7/2(x+2) -> y+6=-7/2x - 14/2

Move the 6 to isolate the y

y=-7/2x -14/2 - 12/2

which equals y= -7/2x -26/2

Hope it helps :)
