The current flowing in the wires will be kept constant while the number of turns of the wires will be changed, then you will measure the strength of the magnetic force.
<h3>
Strength of the magnetic force</h3>
The strength of the magnetic force depends on the number of the turns of the wire and the amount of current flowing in the wires in a given magnetic field.
The relationship between the magnetic force and the number of wire coils on an electromagnet is given as;
F = I x N
where;
- I is the current in the wire
- N is the number of turns
Thus, the current flowing in the wires will be kept constant while the number of turns of the wires will be changed, then you will measure the strength of the magnetic force.

Answer:
wavelength is 20.71 cm
Explanation:
given data
wave = 43.0 vibrations
time = 29 s
wave travels = 430 cm
time t2 = 14 s
to find out
wavelength
solution
we know here wavelength formula that is
wavelength = velocity / frequency .........................1
here frequency = 43 / 29 = 1.4827 Hz
and velocity = 430 / 14 = 30.71 cm/s
so here from equation 1 put all value
wavelength = velocity / frequency
wavelength = 30.71 / 1.4827
wavelength = 20.71 cm
so wavelength is 20.71 cm
Density + mass / volume = 42 / 22 = 1.909 kg / m^3 ( to the nearest thousandth)
