If `u_(1)` and `u_(2)` are the units selected in two systems of measurement and `n_(1)` and `n_(2)` their numerical values, then

If u_(1) and u_(2) are the selected in two system of measurement and n_(1) and n_(2) their nomerical values, then

The same physical quantity is expressed in two different units x_(1) and x_(2) . The corresponding numerical values of the quantity are n_(1) and n_(2) respectively. Then

The numerical values and units of a physical quantity in two different system of units are n_(1), n_(2) and u_(1), u_(2) respectively. Then

The numerical values and units of a physical quantity in two different system of units are n_(1), n_(2) and u_(1), u_(2) respectively. Then

A physical quantity is measured and the result is expressed as nu where u is the unit and n is the numerical value. If the result is expressed in various unit then

When some object is kept at a distances u_(1) and u_(2) from the concave mirror then size of images are found to be same. If magnitude of focal length can be written as ( u_(1)+ u_(2))//n , then what will be the value of n ? |{:(0,1,2,3,4,5,6,7,8,9):}|

If u_(1), u_(2), u (3) "…..." represent the speed of n_(1), n_(2) , n_(3) ,"…..." molecules , then the root mean square speed is "____________" .
