### How many volts should an alternator put out?

A car alternator needs to be putting out at least 13-14 volts (ideally between 13.8 and 14.2 volts) to effectively charge a 12 volt car battery. If the alternator is putting out too much voltage (15+ volts), it is likely your battery acid will boil over out of the battery.

A sphygmomanometer is the gauge used to measure blood pressure. The sphygmomanometer reads both systolic and diastolic pressure. A doctor takes these measurements by putting on the cuff and pumping it up, which cuts off the blood flow.

Many .22 LR cartridges use bullets lighter than the standard 40 gr, fired at even higher velocities. Hyper-velocity bullets usually weigh around 30 to 32 gr (1.9 to 2.1 g) and can have a muzzle velocity of 1,400 to 1,800 feet per second (430 to 550 m/s).

The navy bean got its current popular name because it was a staple food of the United States Navy in the early 20th century. These small white beans are perfect for making baked beans.

Kangaroos hop to move around quickly, and walk on four legs while moving slowly. They can jump backwards, but only a very small distance. They can hop or jump as far as about three times their own height. They can also swim if necessary.
