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?
After the engine is ignited, what is the rocket's speed when the spring has stretched 19.00 cm past its natural length? What would be the rockets speed after travelling the distance if it weren't tied down to spring.
What is the tangential acceleration of a bug on the rim of a 13.0-in.-diameter disk if the disk accelerates uniformly from rest to the angular speed of 77.0 rev/min in 3.40 s.
A coin with a diameter of 3.00 cm rolls up a 30.0 degree inclined plane. The coin starts with the initial angular speed of 60.0 rad/s and rolls in a straight line without slipping. How far does it roll up the inclined plane.
Coherent light from a sodium-vapor lamp is passed through a filter that blocks everything except for light of single wavelength. It then falls on two slits separated by 0.410 . In resulting interference pattern on a screen 2.10 away, adjacent bri..
