The energy associated with the motion of particles in a substance is called

heat

Explanation:

Heat is what a living being feels at a high temperature. Physics understands heat as the energy that is transferred from one system to another or from one body to another, a transfer linked to the movement of molecules, atoms and other particles.

It is important to keep in mind that bodies do not have heat, but internal energy. When a part of this energy is transferred from one system or body to another that is at a different temperature, it speaks of heat. Heat transfer will occur until the two systems are at the same temperature and the so-called thermal equilibrium is reached.

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.
