Answer:

gs = 0.6 m/s^2

Explanation:

Given data:

velocity = 12 m/s

height s = 12t -(1/2) g_s t^2

Given velocity is the derivatives of height

$v(t) = \frac{d}{dt} s(t)$

$= \frac{d}{dt}(12t -\frac{1}{2} g_s t^2)$

$= 12 - g_s t$

when velocity tend to 0 , maximum height is reached

$v(t) = 12 - g_s t$

$0 = 12 - g_s t$

$g_s = \frac{12}{t}$

at t = 20 sec ball reached the max height, so

$g_s = \frac{12}{20} = 0.6 m/s^2$

Answer:Angular width of the electromagnetic wave after it emerges from between the buildings is 2.761 degree

Explanation:

The wavelength of the electromagnetic wave is

$\lambda=\frac{c}{f} \\\lambda=\frac{3\times 10^8}{830\times 10^6} \\\lambda=0.361 m$

Consider two buildings as a single slit, for single slit diffraction dark fringes are located an angle of

$\theta _{p}=sin^{-1}\frac{\lambda}{a}$

where $\lambda$ is frequency, $a$ is space between buildings.

For the first dark fringes

$\theta _{1}=sin^{-1}\frac{\lambda}{a}\\\theta _{1}=sin^{-1}\frac{0.3614}{15}\\\theta _{1}=1.38^{0}$

Angular width of the electromagnetic wave after it emerges from between the buildings is

$\Delta\theta =2\theta _{1}\\\Delta\theta =2\times 1.38\\\Delta\theta =2.761^0$
