The disease was first detected in England in 1986, though sdne scientists think the very first cases started at least ten years before. Cows usually eat only grass and other plants, but farmers had been feeding them a meat and bone mixture that made the cows plumper. But somehow, at least one batch of the mixture had become contaminated with what was then an unknown killer: a prion. By 1993, British farmers were reporting up to one thousand new cases of BSE a week.

reasoning from several particular examples to establish a general principle

answer = d. hope this . : -d

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.
