VA and Watts
ohms and watts
VA and AMPS IS WRONG! For the A+ test it's : Ohms and WattsThe answer is. VA and wattsThanks!
1) Rated Protection of the UPS 2) Run Time. Rated protection is usually in KVA or VA (KilliVolt amps for very large UPS or Volt Amps for smaller UPS). This is because UPS typically have multiple outputs like 120V 240V and possibly 12VDC. Some only list WATTS. This assumes the UPS will have only one Voltage output so the Volts X Amps=Watts was already calculated. There is also something called a "Power Factor" that comes in to play. For computers it is ~60% which means if you are backing up a PC it will take more power than you think or the UPS will run for less time than you think because of the power factor. Runtime is usually presented in a chart since it will vary based on the load it is supporting. A battery has a rated Amp/Hour capacity. Amps per hour. You use a fraction of this over time until there is no more energy. Using Ohms Law you can determine the Amps from Watts or KVA/VA. P=IxE or Power ( watts) = Current( amps) x Electrical energy ( Volts) So I (amps) = P(watts) / E ( volts) . There are other factors like the battery charge level, ambient temperature and losses in cabling etc, that affect the run time in amp hours.
no. i did an experiment and sit ups increase the heart rate more than push ups by 13 beats/minute :)
sit-ups raise your heart beat more
break*
you send it to the pony express then shuv it in your nose
Grown ups is two words.
It would be at the discretion of the shipper. Flat rate could be either USPS, UPS, Fed-Ex or whatever method of shipping is chosen by the shipper for a "Flat Rate". Also, USPS has flat rate boxes and envelopes.
push ups, pull ups and maybe even sit ups
The most easiest way is to get yourself a little device that measures the compsumption of power by the set. When you know what it uses, take that amount and add 10%-15% to it. That will be the capacity of the ups you will need. Keep in mind though that a ups is ment to provide power for a limited amount of time during a power failure.
UPS Ground is the most cost efficient of the two but standard is significantly faster
