A) Using Excel, or some other graphing software, plot the values of y as a function of x. (You will not submit this spreadsheet.

However, the results will be needed later in this problem).
x y
1 2.5
2 3.3
3 4.5
4 4.9
5 7.0
B) Use the trendline option to draw the best fit line for the above data and use it to determine the slope and y-intercept.

Answer:

   y = 1.06 x + 0.14

            r² = 0.95

Explanation:

a) To make this graph, a spreadsheet-type calculation program is used, see attached.

On the y axis are the measured values

On the x-axis, the values ​​checked in the experiment are placed.

From the graph we see that a linear graph and that one of the values ​​has a strong deviation with respect to the others

b) The red line is the best straight line that can be drawn,

    for this the quality ajust is r²  

the closer to 1 the better the fit

           

the equation of the line is

            y = 1.06 x + 0.14

            r² = 0.95

Scientific work is currently underway to determine whether weak oscillating magnetic fields can affect human health. For example
iragen [17]

Given Information:

Magnetic field = B = 1×10⁻³ T

Frequency = f = 72.5 Hz

Diameter of cell = d = 7.60 µm = 7.60×10⁻⁶ m

Required Information:

Maximum Emf = ?

Answer:

Maximum Emf = 20.66×10⁻¹² volts

Explanation:

The maximum emf generated around the perimeter of a cell in a field is given by

Emf = BAωcos(ωt)

Where A is the area, B is the magnetic field and ω is frequency in rad/sec

For maximum emf cos(ωt) = 1

Emf = BAω

Area is given by

A = πr²

A = π(d/2)²

A = π(7.60×10⁻⁶/2)²

A = 45.36×10⁻¹² m²

We know that,

ω = 2πf

ω = 2π(72.5)

ω = 455.53 rad/sec

Finally, the emf is,

Emf = BAω

Emf = 1×10⁻³*45.36×10⁻¹²*455.53

Emf = 20.66×10⁻¹² volts

Therefore, the maximum emf generated around the perimeter of the cell is 20.66×10⁻¹² volts
