Two radio antennas are 130 m apart on a north-south line. the two antennas radiate in phase at a frequency of 3.6 mhz. all radio measurements are made far from the antennas. the smallest angle, reckoned east of north from the antennas, at which constructive interference of two radio waves occurs, is closest to:

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
