*brainliest if answered with in 5 min* at which temperature does the motion of atoms and molecules stop? a. 0°c b. 0 c c. 0°k d. 0 k

This is really sneaky.  Of course it's going to be "Absolute Zero" ... the bottom of the Kelvin scale ... but what in the world is the difference between choice-C and choice-D ? ?

On the Kelvin scale, just to be different I guess, the unit of temperature is not called "the degree" Kelvin.  On that scale, the unit is called "the Kelvin", and the temperature is called 'so many' "Kelvins".

So the correct choice is D ... "zero Kelvins".

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.

the force on the thing and the distance the force moves the thing
