<h2>Answer</h2>
25 miles/hour
<h2>Explanation</h2>
Given that,
<em>A pilot can travel with wind = 416miles </em>
<em>A pilot can travel against wind = 336miles</em>
<em>A pilot can speed without wind = 235miles/hour </em>
<em />
<em />
let wind speed = v miles/hr
pilot's speed with the wind = 235<em>+ v</em>
pilot's speed against the wind = 235 - v
<h2>
Time = distance / speed</h2>
416 / (235 + v) = 336 / (235 - v)
416(235 - v) = 336(235+v)
97760 - 416v = 78960 + 336v
97760 - 78960 = 416v + 336v
18800 = 752v
v = 18800/752
v = 25 miles/hour
wind speed = 25 mph
Answer:
It increases to three times its original value. Given the same radius of wire and other constant property. current is directly proportional to the magnetic field.
B1=B2
MoI1/2pir=MoI2/2pir; cancel the same values on both sides
B2/B1=6/2 =3
