Gas stored in a tank at 273 k has a pressure of 388kpa. the safe limit for the pressure is 825kpa at whst temperature will gas reach this pressure

When a neutral charge, comes into contact with a positive charge they repel each other nothing happens the neutral charge becomes negative they attract each other

The magnetic field inside a superconducting solenoid is 4.50 t. the solenoid has an inner diameter of 6.20 cm and a length of 26.0 cm. determine (a) the magnetic energy density in the field and (b) the energy stored in the magnetic field within the solenoid.

Metals are good conductors of electricity because they
