Musya8 [376]

Answer:

$v=0.8m/s$

Explanation:

From the question we are told that

Distance $d=1.5m/sm/s$

Time $t_1=60s$

Time $t_2=90s$

Generally the the equation for the distance traveled is mathematically given as

$d=vt$

$d=1.5*90$

$d=138m$

Generally equation for speed of side walk is mathematically given as

$d=(v+u)t$

$v=\frac{d}{t}-u$

$v=\frac{138}{60}-1.5$

$v=0.8m/s$

What is the wavelength of an FM radio

AleksandrR [38]

V = 3.0 x 10⁸ m/s (This is the same for all types of electromagnetic waves)

f = 88.6 MHz = 8.86 x 10⁷ Hz

λ = ?

V = fλ

λ = V/f = (3 x 10⁸)/(8.86 x 10⁷)

= 3.4 m [Ans]

Hope this helps!
