Answer:
Think of it as two triangles. A square consists of a 45 45 90 triangle. So 1 would equal x root 2. Then you solve that equation and end up with (root 2)/2
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.
C, an enormous road building project
Answer:
"The asthenosphere (Ancient Greek: ἀσθενός [asthenos] meaning "without stength", and thus "weak", and σφαίρα [sphaira] meaning "sphere") is the highly viscous, mechanically weak and ductile region of the upper mantle of the Earth. ... In some regions the asthenosphere could extend as deep as 700 km (430 mi)."
