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.

The primary sex organs for men are called testes and ovaries for the women. They produce sex cells called gametes and they secrete sex hormones.
There's multiple reasons a defense lawyer may admire Newtons 3rd Law but mainly it's because whenever for example someone is accused or did something there's a reason and also that person's going to have help.
Answer:
The speed of the electron is 1.371 x 10⁶ m/s.
Explanation:
Given;
wavelength of the ultraviolet light beam, λ = 130 nm = 130 x 10⁻⁹ m
the work function of the molybdenum surface, W₀ = 4.2 eV = 6.728 x 10⁻¹⁹ J
The energy of the incident light is given by;
E = hf
where;
h is Planck's constant = 6.626 x 10⁻³⁴ J/s
f = c / λ
Photo electric effect equation is given by;
E = W₀ + K.E
Where;
K.E is the kinetic energy of the emitted electron
K.E = E - W₀
K.E = 15.291 x 10⁻¹⁹ J - 6.728 x 10⁻¹⁹ J
K.E = 8.563 x 10⁻¹⁹ J
Kinetic energy of the emitted electron is given by;
K.E = ¹/₂mv²
where;
m is mass of the electron = 9.11 x 10⁻³¹ kg
v is the speed of the electron
Therefore, the speed of the electron is 1.371 x 10⁶ m/s.
It's (whatever number comes after 'hold') divided by 2.5 .
