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:

it would be c. predictability

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
