Physics Questions

Pace Count is a way to measure to Ground Distance.

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

A nanosecond (ns) is an SI unit of time equal to one thousand-millionth of a second or one billionth of a second.

• That is, 1/1,000,000,000 of a second, or 10^−9 seconds.

Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth.

Middle latitude cyclones are fueled by air high in the atmosphere.

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.

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.

At any given speed, momentum is directly proportional to mass of an object.
