The wires are twisted around each other in a twisted pair cable for the purpose of blocking off any external electromagnetic interference.
A twisted-pair cable is a form of cable system used for telecom services as well as most current wired networks. Twisted pairs are composed of two insulated copper wires that are been twisted together. The circuit is formed by a twisted pair of wires that may carry data. These pairs are twisted to prevent interference or noise caused by neighboring pairs.

Answer:
Explanation:
Let the required velocity of rocket be v .
We shall use the formula of time dilation to find the velocity of rocket .
t =
t = 430
t' = 38
= .0078
=.9922
= .996
v = .996 x 3 x 10⁸ m /s
= 2.988 x 10⁸ m /s
B )
Kinetic energy of rocket
= 1/2 m v²
= .5 x 20000 x (2.988 x 10⁸ )²
= 8.9 x 10²⁰ J .
C )
This energy is 8.9 times the energy requirement of United states in the year 2005 .
Answer:
E. The force on A is exactly equal to the force on B.
Explanation:
The force between two charges is given by
where
= Charge on particle 1
= Charge on particle 2
r = Distance between the charges
k = Coulomb constant =
This force will be exerted on both the charges equally.
So, The force on A is exactly equal to the force on B
