SM/LAN which would demonstrate that there is a Cisco Internal Services Module or a remote LAN card. LAN interfaces the PC equipment in a confined territory, for example, an office or home. Normally, LANs utilize wired associations with connect the PCs to each other and to an assortment of fringe gadgets, for example, printers. LAN clients can speak with each other by talk or email.

The purpose of the ISM/WLAN indicator light on the back plane of the router is The Cisco 1941 router can support a Cisco Internal Services Module that can enhance the intelligence and abilities of the router to perform activities like intrusion prevention scanning. The Cisco 1941 router can be also equipped with a WLAN Card or Wireless LAN card for supporting wireless local area networks.

Answer:

v_s = 34.269 m / s

Explanation:

This is a Doppler effect exercise, in this case the observer is fixed and the sound source is moving.

f ’= f $\frac{v}{v \mp v_s }$

where the negative sign is used for when the source approaches the observer and the positive sign for when the source moves away from the observer

In this case when f ’= 5500 Hz approaches and when f’ = 4500 Hz moves away, let's write the two expressions together

5500 = f ( $\frac{v}{v - v_s }$ )

4500 = f ( $\frac{v}{v + vs}$ )

let's solve these two equations

$\frac{5500}{4500} = \frac{v+v_s}{v-v_s}$

1.222 (v-v_s) = v + v_s

v_s (1+ 1.22) = v (1.222 -1)

v_s = v $\frac{0.222}{2.223}$

the speed of sound in air is v = 343 m / s

v_s = 343 0.09990

v_s = 34.269 m / s

What is static electricity and how does it differ from current electricity

sp2606 [1]

Answer:

1. Static electricity is caused by the build up of electrical charges on the surface of objects, while current electricity is a phenomenon from the flow of electrons along a conductor. 2. When objects are rubbed, a loss and/or gain of electrons occurs, which results in the phenomenon of static electricity.

Readme [11.4K]

A material must readily accept electron flow to be a good conductor of electricity. Electrical conductors are electrical charge carriers with electrons that move with ease from atom to atom when charged with voltage. Examples of good conductors are copper, brass, steel, gold, and aluminum.

GuDViN [60]

Answer:

$3.16097\times 10^{-8}\ C$

Explanation:

T = Tension on the string

E = Electric field

$\epsilon_0$ = Permittivity of free space = $8.85\times 10^{-12}\ F/m$

As the forces balance themselves we have the equations

$Tcos30=mg$

$Tsin30=Eq$

Dividing the equations we get

$tan30=\dfrac{Eq}{mg}\\\Rightarrow E=\dfrac{mgtan30}{q}\\\Rightarrow E=\dfrac{7.1\times 10^{-3}\times 9.81tan30}{0.161\times 10^{-6}}\\\Rightarrow E=249770.33291\ N/C$

Electric field is given by

$E=\dfrac{Q}{A\epsilon}\\\Rightarrow Q=EA\epsilon\\\Rightarrow Q=249770.33291\times 0.0143\times 8.85\times 10^{-12}\\\Rightarrow Q=3.16097\times 10^{-8}\ C$

The magnitude of the charge on each plate is $3.16097\times 10^{-8}\ C$
