On what principle does calorimetry depend?

The answer is the law of conservation of energy.

Explanation:

Law of conservation of energy: It states that the energy is neither created nor destroyed. It can be transferred from one form to another.

According to the law of calorimetry, the total heat gain by the cold body is equal to the total heat loss by the hot body. There is no loss of heat in the surrounding. Heat is a form of energy. It is transferred only from one object to another.

Therefore, calorimetry depends on the law of conservation of energy.

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.
