An=200-turn solenoid having a length of l=25 cm and a diameter of 10 cm (r=5 cm) carries a current of i= 0.30 amp. (a) what is the magnetic field near the center of the solenoid? (b) what is the magnetic flux through an annular ring having an inside diameter of d=2.0 cm and an outside diameter of d=8.0 cm if the plane of the ring is perpendicular to the axis of the solenoid? solve using variables first and plug numbers at the end. hint: calculate the field of one loop as a function of z and then add up all the loops.

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
