The original volume and pressure of a gas sample were 8.0l and 125 kpa. if the pressure is increased to 200.0 kpa while the temperature is kept constant, what is the new volume of the gas in the container?

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?
