Which of the following is true of the Celsius scale? a. 212 degrees is the boiling point of water. b. 0 degrees is absolute zero. c. 0 degrees is the freezing point of water. d. 32 degrees is the freezing point of water. Please select the best answer from the choices provided A B C D

The correct answer is C., or ¨0 degrees is the freezing point of water¨.

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.
