What is the wavelength of an fm radio signal that has a frequency of 91.7 mhz?
Digiron [165]

Answer:

The wavelength of the radio wave will be 3.271 m

Explanation:

We have given frequency of the radio signal f=91.7MhZ=91.7\times 10^6Hz

Speed of the light c=3\times 10^8m/sec

We have to find the wavelength of the radio signal

We know that wavelength is given by \lambda =\frac{c}{f}=\frac{3\times 10^8}{91.7\times 10^6}=3.271m

So the wavelength of the radio wave will be 3.271 m

B)
Vlad1618 [11]

Answer:

a) 16m/s b) 192m

Explanation:

v1=32m/s a=-2m/s^2 t=8s v2=? d=??

a) I will use this equation v2= v1 + a*t

v2= 32m/s + -2m/s^2 * 8s

v2= 32m/s + -16m/s

v2= 16m/s

b) v2^2=v1^2 + 2ad

rearranging

v2^2-v1^2=2ad

v2^2-v1^2/2= a d

v2^2-v1^2/2a=d

16m/s^2 - 32m/s^2/ 2 x-2m/s^2 =d

d=192m
