The ball's gravitational potential energy is converted into kinetic energy as it falls toward the ground.
<h3>How can the height of a dropped ball be determined?</h3>
Y = 1/2 g t 2, where y is the height above the ground, g = 9.8 m/s2, and t = 1.3 s, is the formula for problems like these. Any freely falling body with an initial velocity of zero meters per second can use this formula. figuring out how much y is.
A ball drops from the top of a building and picks up speed as it descends. Its speed is increasing by 10 m/s every second. What we refer to as motion with constant acceleration is, for example, a ball falling due to gravity.
The ball's parabolic motion causes it to move at a speed of 26.3 m/s right before it strikes the ground, which is faster than its straight downhill motion, which has a speed of 17.1 m/s. Take note of the rising positive y direction in the above graphic.

Answer:
Check image.
Explanation:
This is what my solution is, not a professional tutor so take my answer with a grain of salt and check.
Answer:
Electrons in different metals
Explanation:
When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. The different mix of energy differences for each atom produces different colours. Each metal gives a characteristic flame emission spectrum.
The given statement is true.
Pressure is defined as force per unit area.
In mathematical terms,
Pressure = force/area
pressure is directly proportional to the force on the object
pressure is indirectly proportional to the area on which force acts
Hence the given statement is true

The positions to be considered are the position of the acorn and the earth.
<h3>What is potential energy?</h3>
The potential energy is the energy that is possessed by a body by virtue of its position. Hence, the potential energy of a body changes as its position changes.
Hence, to determine how the potential energy of the acorn changes in relation to the earth, the positions to be considered are the position of the acorn and the earth.
