A receiver requires 10nW as input power if all the system losses add up to 50dB then how much power is required from the source?
here, the power required by the receiver is the output power and that required from the source is input power. Gain in dB=10 log(output power/input power) we have, loss in dB = -gain in dB = 10 log(input power/output power) or, 50 = 10 log(input power/10nW) or, anti-log(5) = input power/10 nW so the power required from the source is antilog(5)*10nW = 1 mW
What is the effect of power factor on the cost of generation?
The effect of low (or 'poor') power factor is that a given load requires more load current than at high power factors. So, to accommodate these higher currents, a greater volume of copper is required in the supply cables, switchgear, transformers, etc. So much greater capital costs are required if low power loads are supplied.

How much power does a 300 VA UPS consume?
From the description given its output power would be 300 Volt-Amps which is almost the same as 300 Watts but may not be, depending on the power factor. If we allow, say, 10% extra for power losses, the UPS (Un-interruptable Power Supply to those who don't know what such things are) may consume about 330 Watts from your building's main electrical power supply. If you need to have a more accurate idea of the power it takes why not look at the rating plate on the UPS unit itself? Or if you had a Wattmeter you could measure the maximum power drawn when it is working at full load charging its batteries.

How much power is required to do 100 j of work on an object in a time of 5 how much power is required if the same work is done in 1 s?
Power is the rate at which work is done. To find the power required to do 100 J of work in 5 s, divide the work by the time: 100 J / 5 s = 20 watts. If the same work is done in 1 s, the power required would be 100 watts, as power is inversely proportional to time.
