Question: The USB Battery Charging Specification Revision 1.2 (released in 2010) makes clear that there are safety limits to the rated current at 5 A coming from USB 2.0. On the other hand, several changes are made and limits are increasing including allowing 1.5 A on charging downstream ports for unconfigured devices, allowing high speed communication while having a current up to 1.5 A, and allowing a maximum current of 5 A. Also, revision 1.2 removes support for USB ports type detection via resistive detection mechanisms.
Try to answer this question if possible: When was USB Battery Charging Specification Revision 1.2 released?
Answer: in 2010
Question: Today, computer security comprises mainly "preventive" measures, like firewalls or an exit procedure. A firewall can be defined as a way of filtering network data between a host or a network and another network, such as the Internet, and can be implemented as software running on the machine, hooking into the network stack (or, in the case of most UNIX-based operating systems such as Linux, built into the operating system kernel) to provide real time filtering and blocking. Another implementation is a so-called physical firewall which consists of a separate machine filtering network traffic. Firewalls are common amongst machines that are permanently connected to the Internet.

Answer: unanswerable
Question: When used with a load that has a torque curve that increases with speed, the motor will operate at the speed where the torque developed by the motor is equal to the load torque. Reducing the load will cause the motor to speed up, and increasing the load will cause the motor to slow down until the load and motor torque are equal. Operated in this manner, the slip losses are dissipated in the secondary resistors and can be very significant. The speed regulation and net efficiency is also very poor.
Try to answer this question if possible:  What will a motor do if the load is not reduced?
Answer: unanswerable
Question: During the 14th century in the northeastern part of the state nomad tribes by the name of Jornado hunted bison along the Rio Grande; they left numerous rock paintings throughout the northeastern part of the state. When the Spanish explorers reached this area they found their descendants, Suma and Manso tribes. In the southern part of the state, in a region known as Aridoamerica, Chichimeca people survived by hunting, gathering, and farming between AD 300 and 1300. The Chichimeca are the ancestors of the Tepehuan people.
Try to answer this question if possible: The Jornado painted onto what surface?
Answer:
rock
