Does visible light make up a relatively large part or a relatively small part of the electromagnetic spectrum?
Yakvenalex [24]

Answer:

Relatively small part of the electromagnetic spectrum

Explanation:

Let us take a look at the electromagnetic spectrum

Radio waves

Wavelength = 10^3\ m

Microwaves

Wavelength = 10^{-2}\ m

Infrared waves

Wavelength = 10^{-5}\ m

Visible waves

Wavelength = 0.5\times 10^{-6}\ m

Radio waves

Wavelength = 10^3\ m

Ultraviolet waves

Wavelength = 10^{-8}\ m

X ray waves

Wavelength = 10^{-10}\ m

Gamma ray waves

Wavelength = 10^{-12}\ m

So, it can be seen that the visible light makes up a relatively small part of the electromagnetic spectrum.

What is a characteristic of a default static route? ​?
Vaselesa [24]

A default route is an exceptional kind of static route because the subnet and network you are identifying as the target for the traffic that it would equal to all zeros. The characteristic of a default static route would be it classifies the gateway IP address to which the router directs all IP packets for which it does not have a knowledge or static route.

Suppose you increase your walking speed from 6 m/s to 13 m/s in a period of 1 s. What is your acceleration? m/s2
ziro4ka [17]
Average acceleration is
Change in Velocity/change in time
So you could then do Vf-Vi/Tf-Ti
Which would look like 13m/s-6m/s / 1s-0s
Which then is 7m/s/1s which means the acceleration is 7m/s^2

Answer:

The amplitude  is  A =  90.2 \ m

Explanation:

From the question we are told that

    The frequency of when sound is approaching observer is   f = 392 Hz

     The frequency as the move away from observer  is  f_ a =  330 \ Hz

    The time between the pitch are t =  10 \ s

Here you are the observer and your friends are the source of the sound

The period is mathematically evaluated as

       T =  2 t

as it is the time to complete one oscillation which from on highest pitch to the next highest pitch

Now T can also be mathematically represented as

          T = \frac{2 \pi}{w}

Where  w is the angular velocity

=>   \frac{2 \pi}{w}  =  2 * 10

=>   w =  0.314 \ rad/sec

Now using Doppler Effect,

   The source of the sound is approaching the observer

The

          f = f_o (\frac{v}{v- wA} )

         392  = f_o (\frac{v}{v- wA} )

Where A is the amplitude

    So when the source is moving away from the observer

         f_a =  f_o (\frac{v}{v+ wA} )  

        330  =  f_o (\frac{v}{v+ wA} )  

Here  f_o is the fundamental frequency

Dividing the both equation  we have

           \frac{392}{330}  =  \frac{f_o(\frac{v}{v-wA} )}{f_o(\frac{v}{v+wA}}

           1.1878  = \frac{v+wA}{v-wA}

         1.1878 v -  1.1878 wA = v+wA

        1.1878 v = 2.1878 wA

=>     A =  \frac{(0.1878 * (330))}{(2.1878)* (0.314)}

         A =  90.2 \ m
