2) What does the specific heat capacity of a material tell you about how easy it is to heat up that material

See the explanation below

Explanation:

In order to understand in a better way what the specific heat is, we must analyze the units of measurement of this scalar magnitude.

or [kJ/kg*°C]

For example for water Cp = 4.1 [kJ/kg*°C]

That is, to increase the temperature by one degree celsius in one kilogram of water, 4.14[kJ] of energy is required.

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.
