Answer:

1. Each station can detect how far away the epicenter was. So each station basically has a circle made of possible epicenters. When you have three, you narrow it down to one, final point.

2. Below the tectonic plate is a magma chamber that is shooting up mafic magma. As it emerges, it creates an island. The plate that the magma is puncturing is also happening to be moving, so it makes one island, and it floats on. Think of it as a chimney. It blows a puff of smoke, the wind blows it away. Then another puff emerges, and so on. Those other islands no longer sit on the source of the volcano.

3. Metamorphism occurs when there is enough pressure and heat in order to rearrange the structures of each mineral into a new mineral. Contact metamorphism occurs when lava shoots through and touches other rocks, which heats them up and driving metamorphism. In contact, there is no pressure. In regional, there is a large area of both heat and pressure being applied on the rocks.

If an object accelerates from rest, what will its velocity be after 1.3 s if it has a constant acceleration of 9.1 m/s^2?
HACTEHA [7]

\text{Given that,}\\\\\text{Initial velocity,} ~v_0 = 0~ \text{m~s}^{-1}\\\\\text{Time,  t = 1.3~sec}\\\\\text{Acceleration, a = 9.1 m s}^{-2}\\\\\\\\\text{Velocity,}\\\\v = v_0  +at\\\\\implies v = 0 + 9.1 \times 1.3 = 11.83~~ \text{m~s}^{-1}

What is the force due to gravity of a 38 kg student?
alukav5142 [94]

Answer:

F_g = 372.78 N

Explanation:

Formula for force of gravity is;

F_g = mg

Where;

m is mass

g is acceleration due to gravity

We are given;

Mass = 38 kg

Acceleration due to gravity has a constant value of 9.81 m/s²

Thus;

F_g = 38 × 9.81

F_g = 372.78 N

which of the following refers to the motion of an object falling straight down with only the force of gravity acting on it​
MrRissso [65]

Answer:

Since you haven't provided any choices, then the answer is "Free Fall Motion."

Explanation:

In order to learn more about the answer, let's discuss what free fall motion is.

Free Fall- In Physics, this refers to any body motion that is acted upon solely by <u>"gravity."</u> The acceleration in free fall is always downward and there's the absence of other forces. Take note that the<em> acceleration should be the same and is independent of the object's mass. </em>This acceleration is called "acceleration due to gravity."

Gravity- This refers to the force that pulls any object towards the center of the earth.

<u>Examples of Objects in Free Fall Motion</u>

1. A ball dropped at the top of a building.

2.  Dropping a coin from a table.

The ball and the coin are both in free fall motion because they are being pulled by gravity towards the earth. Their acceleration is also constant and there are no other forces acting upon them.
