Answer:
has a radius of 2439 km (1524 mi), and the metallic iron-nickel core is believed to make up about 75% of this distance. Measurements of the planet's magnetic field made by Mariner 10 as it flew by the planet indicates that this core is likely to be hot and fluid.
Answer:
Water in an artificial lake held behind a dam
Explanation:
Potential energy is energy that can be converted to kinetic energy, for example, an object at a certain height has potential energy because we can drop the object to have kinetic energy.
Therefore, the best example of potential energy is water in an artificial lake held behind a dam because without the dam, the water will start to move and it becomes the energy into kinetic energy.
The gravitational potential energy as a rollercoaster converts to kinetic energy when it moves downhill.
<h3>
What is kinetic energy?</h3>
The kinetic energy of an object or body is due to its motion. When the roller coaster moves downhill it accelerates, thus the gravitational potential energy as a rollercoaster converts to kinetic energy.
The gravitational potential energy of an object or body is due to its position above the ground.
Therefore, the gravitational potential energy as a rollercoaster converts to kinetic energy when it moves downhill.

The answer would be permeable i know this because i just took the test on apex.
The correct answer is the following.
The forces that act on the piano are: 2) gravitational force acting on the piano (piano's weight). 5) force of the floor on the piano (normal force). 7) force of Chadwick on the piano.
As we see in the picture that I have attached is Chadwick pushing the piano in a horizontal plane. So Chadwick is applying a force that produces an acceleration. It is his force on the piano plus the acceleration of the weight of the piano, it's a gravitational force. This is pure physics applied to an object.
