Answer: C ; Rising magma from the seafloor.

Explanation:

Underwater volcanoes erupting can cause the magma to rise above the seafloor therefor hardening and eventually creating islands. Upon this factor, you might know that another word for an oceanic island is a volcanic island, this is important to remember so that when you see a question like this one you will automatically know the answer without having to checkback.

The natural factor that is most likely to support the formation of an oceanic island is the rise of magma from the seafloor. Oceanic islands are also otherwise known as volcanic islands. When volcanoes erupt, they create layers of lava that break the surface of the water. When the tops of the volcanoes emerge, an island is created.

if i release one steel ball from the top of a ramp and the other ball from the 40cm mark will they have the same acceleration?

solniwko [45]

Answer:

Yes, they will also have the same acceleration. Acceleration is controlled by the amount of weight (def. amount of gravitational pull on a given object) that the ball has. For one ball to accelerate quicker than the other, it would need a propulsion element, which it does not.

I attached the requested diagram.

In the case of the magnetic field in a bar by convention, the direction of the field is taken out of the north pole and towards the south pole of the magnet. These types of images are commonly made of some ferrous material.

In the case of the horseshoe magnet, the highly concentrated magnetic field is distinguished between its legs. In the figure it is shown in a contribution from North to South, again by agreement, however outside the two poles, the magnetic field falls rapidly. A horseshoe magnet is basically a bent bar magnet.

A ball is dropped from a height of 23.5 meters. Assuming no air resistance, how many seconds will it take the ball to hit the

Alex Ar [27]

Answer:

About 2.19 seconds

Explanation:

$d=v_ot+\dfrac{1}{2}at^2$

Since the ball is dropped from rest, there is no initial velocity, and you can write the following equation:

$23.5=\dfrac{1}{2}(9.8)t^2 \\\\t^2\approx 4.79 \\\\t\approx 2.19s$

Hope this helps!

How can one object affect the motion of another without touching it?

stealth61 [152]

By non-contact forces (e.g. gravitational force and electric force)

Explanation:

In order for an object to exert a force on another object, the two object can also be not touching each other. In fact, there exist some non-contact forces in nature.

Concerning macroscopic objects, the two main non-contact forces acting between objects are:

- The gravitational force: this force is exerted between every object that has mass. It is always attractive, and its magnitude is given by

$F=G\frac{m_1 m_2}{r^2}$

where

$G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2}$ is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between them

- The electric force: this force is exerted between objects that have electric charge. It can be either attractive or repulsive, and its magnitude is given by

$F=k\frac{q_1 q_2}{r^2}$
