Answer:
<em>The apple's potential energy is 0.9555 Joule</em>
Explanation:
<u>Gravitational Potential Energy</u>
Gravitational potential energy is the energy stored in an object because of its vertical position or height in a gravitational field.
It can be calculated with the equation:
Where m is the mass of the object, h is the height with respect to a fixed reference, and g is the acceleration of gravity, or 9.8 m/s^2.
The apple has a mass of m=0.15 kg and it's located at a height of h=0.65 m. Calculate the potential energy:
The apple's potential energy is 0.9555 Joule
Answer:
A
Explanation:
Molecules is made up from and atom is made up with three tiny elements: protons, neutrons, and electron.
The last one, about the trend of the temperatures in my city.
Those can be measured, and described with numbers that mean the same thing to everybody.
On the other hand, "interesting", "appealing", and "hectic" can't be precisely measured, so they can't be studied scientifically.
Wood, marble, clay, terracotta and even concrete all come in colors and can be classified as natural materials.
