QUES: where is the maximum possible exposure that does not lead to a clipped or bloomed camera output. Typically, the lower limit of the saturation speed is determined by the sensor itself, but with the gain of the amplifier between the sensor and the analog-to-digital converter, the saturation speed can be increased. The factor 78 is chosen such that exposure settings based on a standard light meter and an 18-percent reflective surface will result in an image with a grey level of 18%/2 = 12.7% of saturation. The factor 2 indicates that there is half a stop of headroom to deal with specular reflections that would appear brighter than a 100% reflecting white surface.

How can the saturation speed be increased?
What is the answer?
ANS: with the gain of the amplifier between the sensor and the analog-to-digital converter
QUES: In Mark 15:25 crucifixion takes place at the third hour (9 a.m.) and Jesus' death at the ninth hour (3 p.m.). However, in John 19:14 Jesus is still before Pilate at the sixth hour. Scholars have presented a number of arguments to deal with the issue, some suggesting a reconciliation, e.g., based on the use of Roman timekeeping in John but not in Mark, yet others have rejected the arguments. Several notable scholars have argued that the modern precision of marking the time of day should not be read back into the gospel accounts, written at a time when no standardization of timepieces, or exact recording of hours and minutes was available, and time was often approximated to the closest three-hour period.

What is another reason the times differ so much?
What is the answer?
ANS: no standardization of timepieces, or exact recording of hours and minutes was available
QUES: Roughly one quarter of all zinc output in the United States (2009), is consumed in the form of zinc compounds; a variety of which are used industrially. Zinc oxide is widely used as a white pigment in paints, and as a catalyst in the manufacture of rubber. It is also used as a heat disperser for the rubber and acts to protect its polymers from ultraviolet radiation (the same UV protection is conferred to plastics containing zinc oxide). The semiconductor properties of zinc oxide make it useful in varistors and photocopying products. The zinc zinc-oxide cycle is a two step thermochemical process based on zinc and zinc oxide for hydrogen production.

What kind of process is the zinc zinc-oxide cycle?
What is the answer?
ANS:
thermochemical
