Answer: 0.192 N/m
Explanation:
Well, generally when a Hooke's Law experiment is performed the plot is in fact Force vs Displacement, being the Force (in units of Newtons) in the Y-axis and the Displacement (in units of meters) in the X-axis.
In addition, if we add a linear fit the resultant equation will be the Line equation of the form:

Where  is the slope and
 is the slope and  is the point where the line intersects the Y-axis.
 is the point where the line intersects the Y-axis.
So, if the equation is:

The slope of this line is  which is also the spring constant
 which is also the spring constant  .

Answer:
The correct option is D
Explanation:
In trying to achieve what the student wanted to see, which is to see the relationship between the weight the cord can hold and how long the cord will stretch. Since the origin of the graph is from zero, the value plotted on the vertical axis would be just the length caused by each weights. Thus, <u>the original length would have to be subtracted from the measured length to determine the actual length caused by the weight added to the cord</u>.

The longitude based on the time difference is 15 degrees.
<h3>Longitude of complete rotation of the Earth</h3>
The longitude of a complete rotation of the earth in a 24 hours is calculated  as follows;

<h3>Time difference</h3>
The time difference between the local apparent solar time and the Greenwich time is calculated as follows;

Since it is one hour time difference, the longitude is 15 degrees.

Answer:
1 and 3 
Explanation:
<u>1 and 3  </u>
Increasing coils increases strength
    COOLING the wire would increase current flow and strength of magnet 
Adding an iron core will definitely increase the strength of the electromagnet
