This prevents poachers from killing rhinos for the money their horns would bring. The five types of rhinos are the Sumatran, Javan, black, white, and greater one-horned. Javan rhinos and greater one-horned rhinos have only one horn, while Sumatran rhinos, black rhinos, and white rhinos have two. What they all have in common are large heads, broad chests, thick legs, poor eyesight, excellent hearing, and a fondness for rolling in the mud.
HP Pavilion x360: Battery Life The Pavilionâs 29Wh power pack is small by modern standards, so itâs no surprise that battery life was mediocre â thereâs only so much an efficient processor can do. We ran our Powermark test and the HP lasted for 5hrs 57mins â almost half an hour behind the Lenovo, but less than half of the lifespan of the Asus. Itâs a decent result for a budget laptop, but it pales in comparison to that Asus hybrid, and itâs also far shorter than any decent tablet.
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh. Since voltage is pretty much fixed for a battery type due to its internal chemistry (alkaline, lithium, lead acid, etc), often only the Amps*hour measurement is printed on the side, expressed in Ah or mAh (1000mAh = 1Ah). To get Wh, multiply the Ah by the nominal voltage. For example, lets say we have a 3V nominal battery with 1Amp-hour capacity, therefore it has 3 Wh of capacity. 1 Ah means that in theory we can draw 1 Amp of current for one hour, or 0.1A for 10 hours, or 0.01A (also known as 10 mA) for 100 hours.
