Answer:
Voltage across element X is 49.26 volts
Explanation:
The kirchhoff's voltage law states that the algebraic sum of voltages around a closed loop is equal to zero.
Applying the kirchhoff's voltage law in loop yields,
-160 + V₁ + V₂ + V₃ + Vₓ + 60 + V₄ = 0
-160 + 60 + V₁ + V₂ + V₃ + Vₓ + V₄ = 0
But we know that V = IR
-100 + IR₁ + IR₂ + IR₃ + IRₓ + IR₄ = 0
IR₁ + IR₂ + IR₃ + IRₓ + IR₄ = 100
I(R₁ + R₂ + R₃ + Rₓ + R₄) = 100
I = 100/(R₁ + R₂ + R₃ + Rₓ + R₄)
Substitute the given resistor values
I = 100/(18k + 20k + 45k + 100k + 20k)
I = 100/203k
I = 100/203×10³
I = 0.0004926 A
The voltage drop at element x is
Vₓ = IRₓ
Vₓ = 0.0004926*100×10³
Vₓ = 49.26 V

Answer / Explanation:
Eavesdropping attack is also sometimes refereed to as sniffing attack. It is simply the process by which an attacker or hacker tries to penetrate very suddenly into an unaware individuals network or server with the intention to steal information transmitted over the network or server through that computer.
To prevent such attack, there are several mean which include installing network monitoring software to check who else is connected to the network but the most common method of preventing such attack is to encrypt the Hypertext Transfer Protocol (http) and the way to do this is by securing it with a sort of security key.
On installing the security key, the network becomes encrypted and secured such that whatever network transmitted over the network becomes encrypted and unable to read. The protocol then converts to (https).
Answer:
(d) 2 pF
Explanation: the charge on capacitor is given by the expression
Q=CV
where Q=charge
C=capacitance
V=voltage across the plate of the capacitor
here we have given Q=500 pF, V=250 volt
using this formula C=
=500××
=2×
=2 pF
