Solution

The correct option is B False
False
because,A Joule is equal $= N e w t o n \times m e t e r$ , and a Newton $= m a s s \times a c c e l e r a t i o n$ The unit for mass is kg and for acceleration is m $s^{2}$ . So if a Joule $= N e w t o n \times m e t e r$ , it equals $k g m s^{2} t i m e s m$ . The x meter makes the meter
on top squared so you get Joules $= k g m^{2}$ $s^{- 2}$ .

1 J Is equal to 1kgms−2

The correct option is B FalseFalsebecause,A Joule is equal=Newton×meter, and a Newton =mass×accelerationThe unit for mass is kg and for acceleration is ms2. So if a Joule =Newton×meter, it equals kgms2timesm. The x meter makes the meteron top squared so you get Joules =kgm2s−2.
