Answer:
slope should be <em>positive </em>0.5
Explanation:
Perpendicular lines have opposite slopes
Which of these statements is most likely correct about the stars?
Star 2 attracts Star 1 with a greater gravitational force than Star 1 attracts Star 2.
No, because Third Newton Law states that both forces are equal in magnitude.
Earth exerts almost equal gravitation force on both the stars.
No, because the Universal Gravitational Law, estblished by Newton, states the atraction force to two masses is proportional to the product of the masses.
Star 1 attracts Star 2 with a greater gravitational force than Star 2 attracts Star 1.
No (same reason for the first statement)
Earth exerts greater gravitation force on Star 2 than on Star 1.
Right. This is the correct statement. Given the mass of Star 2 is greater than the mass of Star 1, by the Universal Gravitational Law, the earth exerts greater gravitational attraction on Star 2.

The Antarctic is an incredibly unique environment - it's like nothing ever before! The Antarctic has awesome animals that people will never have seen, which I believe is a huge factor in the tourism rates.
Going to the Antarctic is an adventure to people - they want to survive in a new and special environment that will test their limits in a habitat that they aren't used to. With the extreme cold and special animals, the Antarctic is bound to be a tourist favourite.
The two ions are you most likely to see adsorbed to the exchange complex of a soil in an arid environment are Na+, K+, Ca2+.
What are exchangeable bases in soil?
Exchangeable bases allow alkali and alkaline earth metals (mainly calcium, magnesium, potassium, and sodium) to bind to the organic constituents of clays and soils, to each other and to other positively charged ions in soil solutions. Broadly defined as anything that can be exchanged with ions.
What is the exchange capacity of soil?
The total number of cations a soil can hold, or its total negative charge, is the soil's cation exchange capacity. The higher the CEC, the higher the negative charge and the more cations it can hold. CEC is measured in milliequivalents per 100 grams of soil.
