Five moles of an ideal monatomic gas with an initial temperature of 127∘C expand and, in the process, absorb 1500 J of heat and do 2100 J of work. What is the final temperature of the gas?

Explanation:

We are given that

Initial temperature=

Number of moles=n=5

Heat absorbed,Q=1500 J

Work done=W=2100 J

We have to find the final temperature  of the gas.

Where R=8.314 J/mol-K

Using the formula

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.
