If the kinetic energy of the train decreases from 314 J to 250 J, the gravitational potential energy of the system It increases from 2 J to 66 J.
<h3>What is conservation of mechanical energy?</h3>
The principle of conservation of mechanical energy states that the total mechanical energy of a system is always constant. This means that the sum of the potential and the kinetic energy does not change.
Thus, if the kinetic energy of the train decreases from 314 J to 250 J, the gravitational potential energy of the system It increases from 2 J to 66 J.

A multi-cellular organism is not an exact copy of its parents because the offspring shares genes of both the parents.
<u>Explanation:</u>
- For a multi-cellular organism to reproduce, they require two parents.
- Characteristics are inherited from both the parents. So, an offspring can't b an exact copy of either of its parents.
- When a unicellular organism reproduce, they make an exact copy of its parent as they originate from only one parent.
- Punnett diagram is used to determine what all traits as organism is supposed to inherit from its parents.
- Chromosomes carry the blueprint of life from one generation to another.
- There are 46 chromosomes with 23 inherited from each parents through the process of mitosis. These chromosome makes up 23 pairs all together.
Answer:
potential
Explanation:At this point the energy is stored in a form called potential energy. This means that the system has the potential to do work or to become active thanks here to the weight's position high above the lowest point of its swing.
Answer:
11 V
Explanation:
According to the formula, V = IR
V = 2.75×4 = 11
