Any integer 'i' can be written as i = i/1, which is a rational number. Clearly, 7/2,-5/4, etc... are rational numbers but they are not integers.

Hence, from the above analysis, every integer is a rational number but a rational number need not be an integer.

Therefore the given statement that 'Every rational number is an integer' is FALSE.

The push or pull on an object that causes it to move or stop or change direction is called as Force.

1 Gallon = 3.785 kgs

Gallon is a unit of measurement of liquid.

* It is a temporary memeory which cannot contain information permanently.

Example :: RAM or Random Access Memory

Non-volatile memory is computer memory that can retain the stored information even when not powered.

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.

Deleted files are not permanently removed from the hard drive or the computers memory. Before they are permanently removed from the system they are stored in Recycle Bin. Recycle Bin is a folder or directory where deleted items are temporarily stored. It is also called as trash.
