Electrical current is the flow of moving charges.
Answer: 0.72 AU (108 million km; 67 million mi)
Explanation:
According to the research, the correct answer is to understand the cause and effect relationship in a phenomenon is an action that would improve the qualiy of results when developing an experimental design.
<h3>What is an experimental design?</h3>
It is the alteration of an experimental variable or several at the same time, in an environment strictly supervised by the person who performs the experiment.
In this sense, the researcher can evaluate in what way or for what reason a particular phenomenon occurs, modifying the variables in intensity and being able to evaluate the causes and consequences of the results.
Therefore, in conclusion according to the research, the correct answer is to understand the cause and effect relationship in a phenomenon is an action that would improve the qualiy of results when developing an experimental design.

Answer:
21.375 J
21.375 J
3.49489 m/s
21.375 J
0.62254 m
Explanation:
k = Spring constant = 1900 N/m
x = Displacement of spring = 15 cm
g = Acceleration due to gravity = 9.81 m/s²
m = Mass of block = 3.5 kg
Potential energy is given by
The potential energy of the spring is 21.375 J
As the energy in the system is conserved we get the kinetic and potential energy are equal
The velocity of block is 3.49489 m/s
Again, as the energy of the system is conserved
The gravitational potential energy is 21.375 J
The height the block will reach is 0.62254 m
