Consider a solenoid of length l, n windings, and radius b (l is much longer than b). a current i is flowing through the wire. if the radius of the solenoid were doubled (becoming 2b), and all other quantities remained the same, the magnetic field consider a solenoid of length , windings, and radius ( is much longer than ). a current is flowing through the wire. if the radius of the solenoid were doubled (becoming 2), and all other quantities remained the same, the magnetic field would become one half as strong. would remain the same. would become twice as strong.

Achild throws a ball with an initial speed of 8.00 m/s at an angle of 40.0° above the horizontal. the ball leaves her hand 1.00 m above the ground. how long is the ball in flight before it hits the ground?

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
