Which of the following is an extensive property? select one: a. density b. temperature c. mass d. specific heat e. pressure

C. Mass

Explanation:

The extensive property is that property of material that depends upon the amount of matter (mass) of substance. Thus, in the given options only, mass is the extensive property. All the other properties other than mass are independent of mass.

The simple method to find out the extensive property is to divide the substance into half. If that property for both individual halves also becomes half, then it is dependent on mass and an extensive property. If the property remains same as before for each half, then it is independent of mass and called intensive property such as, density, temperature, pressure, etc.

Thus the correct answer is C. mass

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.

explanation:

it would be c. predictability
