Q. A long, current-carrying solenoid with an air core has 1450 turns per meter of length and a radius of 0.0241 m. A coil of 146 turns is wrapped tightly around the outside of the solenoid. What is the mutual inductance of this system?
Q. An alpha particle (a helium nucleus) is traveling along thepositive x-axis at 1250 m/s when it enters a cylindrical tube ofradius 0.500 m centered on the x-axis. Inside the tube is a uniformelectric field of 4.50*10-4 N/C pointing in the negativey-direction. How far does the particle travel before hitting the tube wall?
Your projectile launching system is partially jammed. It can only launch objects with an initial vertical velocity of 42.0 m/s, though the horizontal component of the velocity can vary.
