Answer:
can't see the picture clearly
Refer to the diagram shown below.
Let d = the horizontal distance from Charlie to the plane.
By definition,
tan(32°) = 1694.8/d
1694.8/d = 0.6249
d = 1694.8/0.6249 = 2712.2 ft
Answer: 2,712.2 ft
1 joule = 6,242e+18ev
20 joule = 20 joule *6,242e+18 ev/joule =1,248e+20 ev
1,248e+20 ev / (10 ev / photon) =1,248e+19 photons.
Start with the distance equation D=RT, then plug in numbers
194=R x 4.2, so all we have to do is divide 194 by 4.2.
Answer: 46.19 kph
