Do push ups increase heart rate more than sit ups and why?

no. i did an experiment and sit ups increase the heart rate more than push ups by 13 beats/minute :)

Can a12v 10ah barttery be used in a ups that's supossed to use 12v 9ah battery?

Yes, a 12V 10Ah battery can be used in a UPS designed for a 12V 9Ah battery, as it has the same voltage and a higher capacity. This means it can provide power for a longer duration without overloading the UPS. However, ensure that the physical dimensions and connectors of the 10Ah battery fit the UPS properly. Always check the manufacturer's specifications to confirm compatibility.


Does standard flat rate shipping come from ups or in the mail?

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.


Two measuremnets to rate capacity of UPS?

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.


How does a computer's UPS work?

It is a secondary battery it stores enough power as in case of yr emergency lamps and utilise it later. UPS is for the purpose to give un-interruptible power supply. This stores the energy in the form of DC by the controlled rectifier (AC - DC converter) and discharge the energy in the form of controlled AC by inverter (DC - AC converter) so as to provide continuous power supply. Here the back up is derived based on the requirement. types: 1. Online Double convertion UPS (Normal High capacity UPS) 2. Online Delta convertion UPS (New technology offline using buck boost Transformers) 3. Offline UPS (economical UPS medium capacity UPS 3 - 30KVA also available in higher capacity) 4. Line Interactive UPS (lower capacity UPS 300VA - max5KVA output will be Squasi Sinewave). UPS are used in home, medical, IT and industrial where the critical load is used.


What materials does ups use?

Encapsulated-air plastic is used for ups.


How can you calculate the capacity of the UPS you need for your home entertainment system?

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.
