Question

if in a practical unit if the unit of mass becomes double and that of unit of time becomes half then it will be equal to dash unit of work​

Answer 1

8joules of work done can be expressed,as

work= 8 joules = 8kg m²/ s²

where normal units mass = kg

length= m

Time = second=s

let the new units be KG,M and S

According to question ,new mass is double that of initial value.

KG = 2kg

M= no change mentioned = so assume same = m

S= s/2

work =8 kg m/ s

=8 (KG/2)*M²/(2S)²

=8/8(KGM²/S²)

=1 Joule of work.
