1). From the frame of reference of a passenger on the airplane looking out of his window, the tree appears to be moving, at roughly 300 miles per hour toward the left of the picture.
2). The SI unit best suited to measuring the height of a building is the meter.
3). 'Displacement' is the straight-line distance and direction from the start-point to the end-point, regardless of the path that was followed to get there.
The ball started out in the child's hand, and it ended up 2 meters away from her in the direction of the wall. So the displacement of the ball from the beginning to the end of the story is: 2 meters toward the wall.
Thermal energy - the internal kinetic energy in a substance caused by vibration of atoms and molecules. Thermal energy is also known as heat.
Radiant energy - is the electromagnetic energy that travels in waves. Radiant energy is kinetic energy that includes light, x-rays, microwaves, and radio waves.
Elastic energy - potential energy produced from stored or released elastic materials. This is stored mechanical energy energy resulting from being stretched or compressed.
Mechanical energy - the energy an object possesses due to movement. Mechanical energy is kinetic energy because it is the movement from one position to another.
Gravitational energy - the potential energy an object has because of position. This is produced from gravitational force acting upon an object.
Chemical energy - the potential energy stored in the bonds of molecules and compounds.
Nuclear energy - potential energy stored in the core (nucleus) of an atom.
Electrical energy - the kinetic energy produced from the movement of an electric charge.

Answer:
Two rocks of equal mass fall to the ground at the same speed.
Explanation:
The four basic forces also called the fundamental forces as they are responsible for all observations of forces in nature.
The four fundamental forces are gravity, electromagnetism, weak nuclear force, and strong nuclear force.
The gravity is the weakest one.
The volcanoes and earthquakes that are along the ring of fire are caused by the amount of movement of tectonic plates in the area. Plates overlap at convergent boundaries called subduction zones. As rock is subducted, it melts and becomes magma.
Hope this helps! :)
