The initial mechanical energy is the potential energy (PE) which can be solved through the equation,
PE = mgh = (40 kg)(9.8 m/s²)(12 m) = 4,704 J
The energy at the bottom is the kinetic energy and can be calculated through the equation,
KE = 0.5mv² = (0.5)(40 kg)(10 m/s)² = 2000 J
Therefore, she lost 2,704 J of energy due to friction
Answer:
All of the following would be true statements about natural substances in this philosophy EXCEPT:___
b) a substance is always composed of other substances ad infinitum
Explanation:
To provide an answer to the question, we analyse each option as follows
a) a substance is in full being when its potentiality has been actualized
According to Aristotle, every thing consist of potential which is natural for them to attempt to develop their potential and a substance with actualizes potential is fully developed.
b) a substance is always composed of other substances ad infinitum
For Aristotelian metaphysician, a semicircle is described by the circle of which it forms a part, because if we describe a circle by a semi circle and a semicircle by a quarter of a circle then we have ad infinitum number of definitions. Therefore, according to Aristotelian metaphysics, a substance is not always composed of other substances ad infinitum.
For example, the statement a man is a man is true but if analysed from the constituents will lead to contradiction.
c) a substance is analyzable into form and matter
According to Metaphysics, without form matter would be without properties does not exist and every matter is with form.
Answer:

Determine the velocity of the wave
This is calculated using:
<em>Hence, the velocity is 0.25m/s</em>
B, reduce the mass. hope this helps
The particles which are in the field of forces means in the field line of forces they experience electric force.
