Answer:

when molten rock cools above the earth's surface

Explanation:

Extrusive Igneous Rocks Extrusive igneous rocks are formed when molten magma spill over to the surface as a result of a volcanic eruption. The magma on the surface (lava) cools faster on the surface to form igneous rocks that are fine-grained.

Answer:

Follows are the solution to this question:

Explanation:

By checking the value in which we have calculated by performing its differentiation of $\frac{a}{3}t^3+bt$ , the correct form of its integer value is calculating with regard to t, that also provides as expected $at^2+b = F(t)$ .

A binary star system consists of two stars of masses m1 and m2. The stars, which gravitationally attract each other, revolve aro

Answer: $a_{2}=\frac{m_{1}}{m_{2}} a_{1}$

Explanation:

The rest of the question is below:

Find a2, the magnitude of the centripetal acceleration of the star with mass m2.

Assuming both stars are describing a uniform circular motion, their acceleration vector is directed towards the center of mass of the system (that's why it's called centripetal acceleration).

Now, according to Newton's 2nd law, the force $F$ is directly proportional and in the same direction as the acceleration.
