Answer:it's 132.2m
Explanation:
Hello !
Because first recall parabolic peak height equation and
given that v=47.4m/s , h=10.5m
- v²sin²(θ⁰)=2ℎ₀
- (47.4)²²(θ⁰)=2(9.81)(10.5)
- θ=17.63
secondly recall parabolic total distance equation
- d₀=²(2θ⁰)/g
- d₀=(47.4)²(2(17.63)⁰)/9.81
- d₀=132.2m
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. ... This proved that radio waves were a form of light!
