Probably because Egypt came under the British sphere of influence, whereas KSA came under the US sphere of influence.
50Hz
No. 5Kva is a power rating, standing for 5 kilovolt/Amps, 5,000 v/a. This is how much a generator or tranformer can handle or output. 50Hz is the frequency of an A/C waveform, power supply, generally used in the UK and influenced countries. 50 cycles per second.
Frequency is defined as the number of cycles per minute. Ex: for a sine wave from " 0 to pi " is a cycle, and this repeats periodically within a interval of time. if frequency of a signal is 50Hz, then you can say that this signal repeats 50 time's a minute..
Frequency is a function of engine speed and the number of poles in the generator end. For instance, a speed of 1500 RPM turning a four-pole generator will produce 50 hz. The formula is: Frequency = (poles/2) * (RPM/60) From the formula, you can see that the same frequency would be produced by a two-pole generator spinning at 3000 RPM.
Not unless the appliance is rated to be used with the two different power supplies. The US uses 120v, 60 Hz if it plugs into a receptacle, and possibly 240v, 60Hz if it is hard wired. The UK uses 240v, 50Hz whether it plugs in or is hard wired. These two power systems are NOT compatible. You may use a US appliance in the UK, and vice versa, only if the appliance is dual rated, i.e. the appliance says 120v/60Hz AND 240v/50Hz on the nameplate. If the appliance only specifies one power supply, it can only be used on that power supply. If this is the case, you may be able to use a travel adapter to operate the appliance.
220v 50Hz
The frequency of operation was decided by the government before they started building their power plants.
According to the Wikipedia article on mains electricity by country, the power in the UK operates at 50Hz. There is a link below to the article.
Supply Frequency in UAE is 50Hz
standard frequency in India is 50Hz
The mains supply in Scotland is 50Hz.
50Hz
at low frequency less than 50hz the voltage gain decreases with decreasing frequency and at mid frequency{50hz to 20khz} the voltage gain is uniform because resistor value are independent of frequency change and at the high frequency votage gain falls.
The mains voltage is 230 volts, and the frequency is 50Hz.

The voltages supported by a UPS power supply in the US ranges from 50Hz, 60Hg or 400Hg frequency conversions. This may not be an exact answer to the question.
Voltage has nothing to with frequency
