Question

In a new system of units, if the unit of power is1 milliwatt, the unit of force is 10-2N, and theunit of time is 1 minute then what will be theunits of mass and length ?1) 6 kg ; 6 m 2) 3 kg ; 3 m3) 2 kg ; 2 m 4) 6 kg ; 1 m​

Answer 1

Answer:

Explanation: i cant understand the value of focrce either 10.2 or 10-2force value

Sorry just now I understand the the meaning of 10-2 Power P = W/t = work/ time = Force x displacement/time

dist s = P x t/ F = (1x10^-3 x 60)/ 10^-2 = 6 m

mass m

Power P = Work w/time t = Forcex distance/ time

P = mal/t

m = Pxt/al = pxt/ l^2/t^2 (l = distance)

m = Px t^3/ l^2 = (1x10^-3 x 60x 60x 60)/ (6x 6) = 6 Kg
