b) 10^2kg-m^2s^-2

hope it helps you

Answer 2

Given: The value of work done is $10^{10}gcm^{2}s^{-2}$

To find: The value of work done in SI units.

Solution:

• The conversion as follows,

         =$10^{3} X 10^{3} X (100)^{2}$ (∴1 Kg=1000g,1m=100cm)

         =$10^{10}gcm^{2}s^{-2}$

• The other way conversion can be done vice versa way.

• Genral information is $1kgm^{2}s^{-2}=10^{7}gcm^{2}s^{-2}$
• SI unit is abbreviated of as French word System International.It is a scientific method to express the magnitudes or quantities.

So, The value of work done in SI units will be d)$10^{3}kgm^{2}s^{-2}$.
