WORK IS =F.S
TORQUE IS=r cross F

how to solve tell me please

it is option d

from essel world to merry go round to circular motion

it is represented by arhenius equation k=Ae raised to(only e)E/RT
k is rate constant
A is frequency
E IS ACTIVATION ENERGY
R IS GAS CONSTANT
T IS TEMPERATURE

want option ok
