The dimension of Young's modulus is written as M^xL^yT^z. Determine the values of x, y and z respectively
- A. x=1, y=-1, z=2
- B. x=-1, y=1, z=-2Correct
- C. x=-1, y=2, z=-2
- D. x=2, y=2, z=-1
Explanation
Young's modulus has the dimensions of pressure/stress: ML^-1T^-2; presented with reduced confidence given the exact printed options did not precisely match this derivation.
