To solve this problem we will apply the concept related to the kinetic energy theorem. Said theorem states that the work done by the net force (sum of all forces) applied to a particle is equal to the change experienced by the kinetic energy of that particle. This is:


Here,
m = mass
v = Velocity
Our values are given as,


Replacing,


Therefore the mechanical energy lost due to friction acting on the runner is 907J
Answer:4. Two charged objects have a repulsive force of 0.080 N. If the distance separating the objects is tripled, then what is the new force? Explanation: The electrostatic force is inversely related to the square of the separation distance.
Explanation:
Weight = m (mass) * g (acceleration due to gravity)
g = 9.80 m/s^2
m = 2.5 kg = 2,500 g
Weight = 2,500 g * 9.80 m/s^2
Weight = 24,500 N
Good conductors are the materials which allow electricity to pass through them easily whereas, bad conductors are the materials which do not allow electricity to pass through them. Good conductors offer less resistance to the flow of current, whereas the bad conductors do not transmit current through them.
The process of science followed my initial ideas e because it involved experiments.
<h3>What is the process of science?</h3>
The process of science or the scientific method refers to the process which scientists follow in their discovery and explanation of natural phenomena.
The scientific method is given below:
- making an observation,
- develop a hypothesis,
- making a prediction,
- conducting an experiment
- analyzing the results
- propound a law
The process of science follows my initial ideas about the process of science because I always thought science involved experiments.
In conclusion, the process of science involves making hypothesis and conducting research.
