Question

In a new system the unit of mass is a kg, unit
of length is ß m and unit of time is y s. the
value of 1 J in this new system​

Answer 1

Explanation:

1J=N.M                                  

N=kgm/sec2

length=m

given

length=Bm

unit of time=y s

so 1j=n.m=kgm/ys^2 *Bm

kgBm^2/ys^2

so the value of 1 j in this new system is

1 J=kgBm^2/ys^2
