Answer:
Waves interact with objects and other waves.
Explanation:
Let t = Theta and p = Phi
Tan t = y/x Then x =y/Tant.
Tant = y/(x-d) x-d = y/Tanp
y/Tant - d = y/Tanp
y -d*Tanr = y*Tant/Tanp
y-y*Tant/Tanp = d*Tanr
y(1 - Tanr/Tanp = d*Tant
y = d*Tant/(1-Tant/Tanp)
The Magnitude of the Vector is 10.39m and the direction of the vector is - 46.7°.
<u>Explanation:</u>
GIven dx=7.14m and dy= -7.55m,
The Magnitude of the Vector=
Magnitude d=
.
d=
d=
d= 10.39m.
