how many millimeters is equal to 0.2 arc seconds?

There is no answer to that question.\n\nMillimeters is a measure of length and arc seconds are a measure of angle. It's like asking how many mm in 30 degrees.\n\nYou need to know the distance to the object or thing that you are measuring to be 0.2 arc seconds across. Then you can use the pythogorean theorem to calculate the length in mm. (As long as the object is reasonably far away, if it is very close then you can't make the approximation of a right triangle.)\n\nadded:\nkirchwey is absolutey correct!\n\nach! its been too many years since I did this stuff!

10 mm = 1 cm, therefore\n100 mm = 10 cm\n1000 mm = 1 m (or 100 cm)\nNow do the rest.....

That is micro meter. It is 10^ -6 m.

Multiply by time...\n\nMeters per second squared is an acceleration... Which is velocity/time.\n\nMultiplying by time will get you velocity... Which is in meters/second.

a nanometer is one billionth (10- 9 ) of a meter\n\na millimeter is one thousandth (10-3) of a meter

Each centimeter (cm) has 10 millimeters (mm).  Centi represents a hundredth of something (ex. meter) and milli represents a thousandth.  So, there are 52 mm in 5.2 cm.  The answer is 5.2 cm.

Use 1 hour = 3600 seconds, and 1 km = 1000 m.\n\n(18/5) km/hour * (1 hour/ 3600 s) * (1000m/1km)=\nsome number from your calculator.\nPhysical dimension will be meters per second

Exactly 299,792,458 meters per second (m/s). I say exactly because at one point the official length of a meter was modified slightly to make c come out to a even number of meters per second, rather than having some annoying decimal places.\n\nStill, most people prefer to round up to 300,000,000 m/s.

tried this problem, but when converting 2cm disance to meters, the acceleration was way out, too large.I used the equation V2 = U2 + 2aS to arrive at the acceleration (deceleration). This might have been the wrong approach.

A micron is a micrometer where the prefix "micro-" means "one in one million.  In particular a micrometer is:\n\n10^-6 meters = .000001 meters\n10^-3 millimeters = .001 millimeters\n3.93700787 × 10^-5 inches = .0000393700787 inches

60 seconds in minute\n60 minutes in an hour\n\nTherefore, 3600 seconds in an hour

2 meters is a little over 6.5 feet. I found this out by typing 2 meters to feet on google.

200 m in 10.70\n\n= 200/1000 Km in 10.70 seconds\n\n= 0.2 Km in 10.70 second \n\n= 0.2/10.7 Km in 1 sec\n\nand since 1 hr has 3600 seconds\n\n(0.2/10.7)*3600 Km / hour = 67.29 Km / Hour or 67.29 KPH
