Answer:
q = square root (4KsL³/k)
The force of extension of the spring is equal to the force of repulsion between the two like charges. Two like charges(positive or negative) would always repel each other and two unlike charges would always attract each other. This electric force between the charges is what is responsible for the stretching of the spring. The electric force causes the spring to increase in length from L to 2L. Equating these forces, that is the electric force between the charges and the elastic force of the spring and rearranging the variables gives the expression to obtain q.

See the attachment below for full solution.
Dependent / Response Variable: factor or condition in a experiment that changes as a result of the independent variable; often called the responding variable. ... Constant: factors or conditions in an experiment that are kept the same in as trials of the experiment. Control: a set up without the variable being tested.
If .45y = 65
Then solving for y would give you: <span>y = 144</span>
The ratio between power of A and power of B is 2
Explanation:
In physics, power is defined as the ratio between the work done and the time taken to do the work:
where
P is the work done
t is the time taken
In this problem, we have:
Person A and person B do the same amount of work --> let's call this work W
Person A does this work in a time of 
, so the power delivered by A is
Person B does this work in a time of 
, so the power delivered by B is
So, the ratio of the powers delivered by the two persons is
