A beta and gamma source, Co-60, was placed in a chamber which was first lined with paper and then, after, with copper and lead. A Geiger counter was used in both cases to detect the emission of radiation. You expect
es -0)
A)
no emissions to be recorded in either case.
B)
strong emissions to be recorded outside the chamber in both cases.
some emissions when the chamber is lined with paper, but none when lead
Lined,
D)
strong emissions when the chamber is paper lined; faint emissions when
lead lined.

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.
