What is the relationship between potential and kinetic energy in chemical reactions?
Select all that apply.
~Kinetic energy transforms into potential energy when changes in the bonds of reacting substances affect the motion of the atoms within them.
~Potential energy transforms into kinetic energy when moving molecules bump into each other and cause the position of their bonds and atoms to change.

Explanation:

because that's how kinetic and potential energy work

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.
