The properties of magma that determines the intensity or nature of volcanic eruptions are: (1) <em>viscosity</em>, (2)<em> temperature</em>, and (3) the <em>amount of dissolved gases</em>. Viscosity describes the flowability of a fluid and its resistance to flow. Magma with low viscosity are more fluid-like and lets gases escape.
-- The spaceship's AVERAGE speed during the acceleration is
(1/2) (58 m/s + 153 m/s))
= (1/2) (211 m/s)
= 105.5 m/s .
In 12 seconds at an average speed of 105.5 m/s,
the ship covers
(105.5 m/s) (12 sec) = 1,266 meters .

<u>The Weight </u>is a vector whose magnitude is the product of the mass m of the object and the magnitude of the local gravitational acceleration. Its always directed toward the center of the Earth.
Answer:
The way in which objects exert forces on each other is described by Newton’s 3rd law of motion
Explanation:
Objects with mass exert forces on each other via the force of gravity. This force is proportional to the mass of the two interacting objects and is inversely proportional to the square of the distance between them. The factors G, M, and rare the same for all masses at the surface of the Earth.
