Calculate the ratio of H+ ions to OH ions at a pH = 8. Find the concentration of Htions to OH-ions listed in
Table B of your Student Guide. Then divide the H+
concentration by the OH concentration Record this
calculated ratio in Table A of your Student Guide.
Compare your approximated and calculated ratios of H+
ions to OH ions at a pH = 8. Are they the same? Why or
why not? Record your explanation in Table A.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
