Question: One example of omnidirectional antennas is the very common vertical antenna or whip antenna consisting of a metal rod (often, but not always, a quarter of a wavelength long). A dipole antenna is similar but consists of two such conductors extending in opposite directions, with a total length that is often, but not always, a half of a wavelength long. Dipoles are typically oriented horizontally in which case they are weakly directional: signals are reasonably well radiated toward or received from all directions with the exception of the direction along the conductor itself; this region is called the antenna blind cone or null.
Is there an answer to this question: What is the main element of an omnidirectional antenna?

Answer: metal rod


Question: Since the formal adoption of digital video broadcasting's (DVB) widescreen HDTV transmission modes in the early 2000s; the 525-line NTSC (and PAL-M) systems, as well as the European 625-line PAL and SECAM systems, are now regarded as standard definition television systems.
Is there an answer to this question:  525 and 625-line systems are not considered what?

Answer: unanswerable


Question: When a USB device is first connected to a USB host, the USB device enumeration process is started. The enumeration starts by sending a reset signal to the USB device. The data rate of the USB device is determined during the reset signaling. After reset, the USB device's information is read by the host and the device is assigned a unique 7-bit address. If the device is supported by the host, the device drivers needed for communicating with the device are loaded and the device is set to a configured state. If the USB host is restarted, the enumeration process is repeated for all connected devices.
Is there an answer to this question: What is started when a USB is first connected to a host?

Answer: enumeration process


Question: The last centuries of philosophy have seen vigorous questions regarding the arguments for God's existence raised by such philosophers as Immanuel Kant, David Hume and Antony Flew, although Kant held that the argument from morality was valid. The theist response has been either to contend, as does Alvin Plantinga, that faith is "properly basic", or to take, as does Richard Swinburne, the evidentialist position. Some theists agree that none of the arguments for God's existence are compelling, but argue that faith is not a product of reason, but requires risk. There would be no risk, they say, if the arguments for God's existence were as solid as the laws of logic, a position summed up by Pascal as "the heart has reasons of which reason does not know." A recent theory using concepts from physics and neurophysiology proposes that God can be conceptualized within the theory of integrative level.
Is there an answer to this question: What two areas are used to say the arguments for God's existence are solid?

Answer:
unanswerable
