Vedclass · Answer

(C) Let the original units be $L$,$v$,and $F$. The new units are $L' = 2L$,$v' = 2v$,and $F' = 2F$.We know that velocity $v = L/T$,so the unit of time $T = L/v$. The new unit of time $T' = L'/v' = (2L)/(2v) = L/v = T$. Thus,the unit of time remains unchanged.We know that force $F = ma = m(v/T)$,so the unit of mass $m = FT/v$. The new unit of mass $m' = F'T'/v' = (2F 	imes T)/(2v) = FT/v = m$. Thus,the unit of mass remains unchanged.We know that momentum $p = mv$. The new unit of momentum $p' = m'v' = m 	imes (2v) = 2mv = 2p$. Thus,the unit of momentum is doubled.We know that energy $E = F 	imes L$. The new unit of energy $E' = F' 	imes L' = (2F) 	imes (2L) = 4FL = 4E$. Thus,the unit of energy becomes four times the original value.Therefore,the correct statement is that the unit of momentum is doubled.

The units of length,velocity,and force are doubled. Which of the following is the correct change in the other units?
