If you indicate that the mass of an object is 17.2 grams then this implies that you have measured its mass to be somewhere between 17.195 and 17.205. If, however, you indicate a mass of 17.2153 then it will be understood that you have measured the mass to be between 17.21525 and 17.21535. In short, the number of decimal points indicates the precision of the measurement (even when those digits are zeroes).
Two points 360 degrees apart. That would be wavelength.
because voltage is the 'electrical potential difference'. since a "difference" can only be evaluated between two points so is voltage :)
The direction of a vector pointing due north is measured in degrees clockwise from the north, with 0° being due north. The direction of a vector pointing due east is measured in degrees counterclockwise from the east, with 0° being due east.
It is the difference between the coordinates of two points in 2-dimensional space, measured in the horizontal direction.

Distance.
Distance in physics refers to the amount of space between two points, measured along a straight line. It is a scalar quantity, meaning it has magnitude but no direction. Distance is commonly measured in meters (m) or kilometers (km).
No, distance refers to the amount of ground covered between two points without considering direction. Direction is a separate concept that indicates the orientation of the movement between the two points.
Between two points
Direction can be measured using a compass, which points towards the Earth's magnetic poles. This instrument uses the Earth's magnetic field to determine north, south, east, and west directions.

Distance is measured using reference points therefore distance, between objects, is relative. Some of the units used can be absolute, the separation between two or more points cannot.
A weather vane is commonly used to find wind direction. It consists of a rotating arrow that points in the direction from which the wind is blowing, allowing people to easily determine wind direction.
