The Answer of $$O P = V _ { 1 } ^ { 2 } + V _ { 2 } ^ { 2 } + 2 \left( V _ { 1 } \right) \left( V _ { 2 } \right) \cos \theta$$ The velocity or ratio wave propagation in free space is 186,000 miles per second. What is the velocity in kilometers per second? Carry the answer to three decimal places.

OP=V12+V22+2(V1)(V2)cos⁡θO P = V _ { 1 } ^ { 2 } + V _ { 2 } ^ { 2 } + 2 \left( V _ { 1 } \right) \left( V _ { 2 } \right) \cos \thetaOP=V12​+V22​+2(V1​)(V2​)cosθ

$O P = V _ { 1 } ^ { 2 } + V _ { 2 } ^ { 2 } + 2 \left( V _ { 1 } \right) \left( V _ { 2 } \right) \cos \theta$
