A rigid tank is filled initially with 5.0 kg of air at a pressure of 0.5 MPa and a temperature of 500 K. The air is allowed to discharge
through a turbine into the atmosphere, developing work until the
pressure in the tank has fallen to the atmospheric level of 0.1 MPa.
Employing the ideal gas model for the air, determine the maximum
theoretical amount of work that could be developed, in kJ. Ignore
heat transfer with the atmosphere and changes in kinetic and potential
energy.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

answer; how far out of place which the object finished relative to the starting location;

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
