Physics Questions

Integrated circuit (IC) is a tiny device that controls electric signals in such electronic equipments as computers and T.V sets. Many integrated circuits contain thousands of electronic parts on a paper - thin chip of silicon. These parts include capacitors, diodes, all in a very small, compact space.

Long sightedness is a common vision condition in which nearby objects are blurry.

In this situation, the person with this condition of the eye where the curvature of the cornea is flat or the axial length of the eyeball is short. When light enters the eye, it does not focus directly on the retina, but focuses beyond the retina. This causes near images to appear out of focus and blurred.

Long sightedness is also called hyperopia, and sometimes presbyopia.

Natural Gas is a Non Renewable Resource of Energy because that does not renew itself once used, unlike the other choices. 

It is a resource that will not be naturally replenished.

"Conservation of energy" refers to the fact that energy cannot be created or destroyed but can be converted from one form to another.

Pace Count is a way to measure to Ground Distance.

Pace Count is nothing but regular single natural step of about 30 inches long.

As water is cooled from 4 deg C to 0 deg C, the water reaches its freezing point and starts forming ice crystals. Then the volume of that ice cubes increases and its density decreases. Hence, it is the reason that ice will float on water as ice has less density than the water.

The easiest way would measure it through half a liter water bottle. There are approximately 16.9 ounces(oz) of water in a 500ml water bottle.

Gallon is an imperial customary volume unit for the U.S.

As we have previously mentioned, the 16.9oz bottle is also known as 500ml in the metric system. According to U.S. standard, 1 gallon stands for 128 fluid oz.

Hence, Number of bottles in 1 gallon = 128/16.9 = 7.57 =~ 8.
