. Out of the following objects, which one has more inertia? A 200 page notebook A tennis ball A pen A football

A football

Explanation:

inertia is the measurement of the resistance of an object to the external force

its value depend upon the mass of an object greater the mass of an object greater would be its inertia so a football has greater mass than a tennis ball a pen and a notebook so it has greater inertia

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.
