a) Estimate the numerical value of a typical walking speed (for a person) in units of mi/hr. Then, convert this value from mi/hr to m/s. (b) Next, estimate the numerical value of a typical running speed (for a person) in units of mi/hr, then convert this number to units of m/s. (c) Repeat this exercise for a typical residential driving speed. (d) Finally, consider a typical toll road or highway driving speed (not during rush hour!). Make your estimate in mi/hr and then convert to m/s.

I think it's correct

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.

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.
