When the author states that the Scrooge of the past had “passion that had taken root, and where the shadow of the growing tree would fall,” what is the “passion” that he is referring to? How is that “passion” seen in the present? From the book a Christmas carol

The passion is his pursuit for money and greed. The passion is seen in the present by him still not helping his family and keeping all this money.

Explanation:

it says in the text that all he wants is money and doesn’t try to help his Poor family

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.
