A dried pea is fired from a plastic drinking straw that has a mass of .50g. If the force exerted on the pea averages 0.4 N over the 0.10 s flight through the straw, (a) at what speed will the pea emerge? (b) what was the impulse imparted to the pea?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
